As mentioned, the topics are koala sightings, numbers, habitat and encounters; perceptions of, and attitudes towards, koalas; threats to koalas; koalas and fire; management issues; past and future translocations; and other key issues. Each topic is analysed with the findings in turn.
3.1. Koala Sightings, Numbers, Habitat and Encounters
Interview data, especially oral history from landholders and community members as well as local histories, bring to light an imagined past of significant koala populations living in many parts of CQ during the late 1800s/early 1900s. Then came the fur harvest, peaking in the late 1920s, and being responsible for the largest single cause of decline in koala numbers. Then followed, and often interwoven by, disease, significant land clearing for six decades at least, and consequently koalas disappeared to a large extent.
Participants commonly mentioned that koalas are very difficult to see to the untrained eye, more so because koalas in CQ mostly occur in low densities [
15]. The landholders do not usually search for koalas. Koalas are generally sighted only when they are easily visible by landowners while working or when they are seen moving along the ground, hence, their numbers could be higher than what people are reporting. Koalas are seen in all kinds of places (Photograph 1). Sometimes koalas are heard, or even smelt rather than seen, especially at night. Most of the interviewees mentioned having sighted only a few koalas on their properties, thus indicating that the frequency of sightings is generally low. However, most sighted koalas were said to be healthy looking. Some interviewees said they are more aware of looking for koalas now because of their increased interest. However, they acknowledge that it can be challenging to spot them as koalas move around a lot and are often not in the same place where they were once sighted. Koalas are most likely seen in eucalypts such as blue gums along creeks or in ironbark areas on higher ground. Other tree species where koalas have been observed in CQ were spotted gum, bloodwood, blackbutt poplar box and lancewood. They are rarely seen in dry areas or around cane farms.

This analysis shows mixed reports about occurrence of koala sightings in CQ. Some people said they have not seen so many koalas in recent times compared to years gone by. Most of the interviewees however said they see more koalas now than they did in the past (but only in certain areas). For example, a landholder along the Peak Downs Highway (PDH) at the bottom of the Eaton Range has noticed koalas on their property only in the last 4-5 years. Likewise, a landholder 15 km to the west of St Lawrence and running into the bottom of the Clarke-Connors Range (CCR), observes koalas but more so in the last 10-15 years compared to earlier times; he hears them at night too. He added that they look healthy, and the numbers might be increasing because of reduced land clearing. Another landholder with a property close to St Lawrence said he has observed up to 24 koalas on his property in recent times. There are examples of stories attesting that significant revegetation by landholders, especially in riparian zones, has seen koala numbers come back and flourish. Where once they saw no koalas for twenty years on a property about seven km south of Sarina, they are now sighting them since 2021. The current sightings are in the revegetated areas along the creek where the trees are mature. These koalas look healthy as well.
The increased sightings could also be partly due to an increased awareness and to improved spotting skills. The general view is that there are more koalas in the northern parts of CQ now compared to 10-30 years ago, indicating that in many areas their numbers appear to be recovering. For example, it was said that koala numbers are once again on the increase in the St Lawrence area, which might be due to drought further west forcing koalas to move eastwards. Typically, koalas move towards wetter areas during drought [
16]. One interviewee from St Lawrence said she thought
Cyclone Debbie in March 2017 severely diminished strong colonies of koala in that area by excessive flooding. But
the koala activity is slowly increasing since then. Some interviewees from in and around Nebo said that
there used to be many koalas around about 50 years ago, then they almost disappeared, and now they are coming back. Other property owners near Nebo have made similar comments, for example, koalas are always on their property
because of the many ironbarks and blue gums along the creek. Another mentioned that she sees a lot of
male koalas passing through forests near Nebo.
The previous owner of a property near Nebo, who has been a local grazier all his life, said that in the past, they have never seen the large number of koalas that we see now. He said that they never used to see them very much at all and now he sees them along the PDH regularly. He thought that their numbers must be increasing to be so noticeable. Even our daughter saw two in two trees beside a spot with road works a week ago on the way from Nebo to Mackay. My wife counted five in the trees on our way to town recently. We certainly believe there is more koala activity today than we saw here in Nebo eight years ago when we moved here. I am not sure that development is impacting their environment, there is not a lot of development happening along the highway that I am aware of. However, it seems that as they are increasing in numbers and we are seeing more, unfortunately also there are more road kills due to the high traffic volume on the PDH. We have heard that they are quite common in Moranbah township so it might be that there is habitat between Nebo and Moranbah and even beyond that may also be significant and perhaps not so well documented. A grazier near Nebo said that koalas are seen in backyards of houses in the Moranbah township.
Creek environments around Nebo have a lot of koalas according to several interviewees. This also relates to the large number of koalas killed by vehicles along the section of PDH that runs between Nebo and Mackay [
15,
17,
18]. A Nebo resident also added that people were finding them dead on the ground with no apparent cause of death. A property owner near Koumala, said he
has seen more koalas than ever in the last five years. This trend fits with other reports from CCR’s landholders. One landholder said
there are plenty of koalas on their property in the greater CCR. Seeing more koalas increases people’s ability to spot them. Several koalas were reported along Clarke Creek, west of St Lawrence. Some areas, for example around Nebo and Clarke Creek, have seen a change in vegetation patterns with more ironbark dominated hillsides becoming highly utilised koala habitat in addition to the blue gum dominated riparian areas. Issues are found in landscapes that are absent of the ironbark and may only have the blue gum riparian habitats. Not all farmers appreciate the benefits of trees in their paddocks, however.
The owner of Clairview Island has observed five healthy koalas on the island at one time in recent years and said that there are also dingoes and feral pigs on the island [
19]. He has recently stopped grazing cattle on the island and has expressed an interest in planting more
Eucalyptus trees, as well as gifting the island to appropriate management authorities as a koala sanctuary [
19]. Reef catchment staff have also spotted koalas on the island and have found signs of koala scats in other locations throughout the central areas of the island [
20]. The island contains a high diversity of koala food trees (about a third is covered in
Eucalyptus woodlands) as well as dams that can be used as watering points for koalas during extreme drought [
20]. Further south, but still north of Rockhampton around Canoona, a few koalas have been sighted during dry times. These koalas were reported as being unwell and often found on the ground at the base of trees.
Koala sightings were reported to us by a few interviewees in areas between Gladstone and Bundaberg and around Miriam Vale and Gin Gin. It was reported that some local koalas were admitted into care at Gladstone Wildlife after being struck by vehicles. It was also mentioned that a koala was sighted in Bulburin National Park west of Gladstone in 2022. The same interviewee also saw one at Anakie Caravan Park, but none around Rockhampton where she lives. One of the interviewees said he recalled seeing healthy koalas in trees beside the Yandaran Creek in the Rosedale/Avondale area north of Bundaberg in the 1980s. Koalas were still found there 10-12 years later, so he thinks the population is persisting. He said a colleague saw some koalas in trees along the Capricorn Highway between Blackwater and Comet. The owner of a large high-value conservation property on the Bucca Range near Gin Gin has seen koalas there. She and her family regularly heard and saw koalas on the property when they first bought it 30 years ago. Then a lot of land clearing occurred in the area before tighter vegetation management laws came in, which resulted in seeing far fewer koalas, and they moved into restricted pockets. She has not seen any koalas on her property for two years now but believes there are still koalas in the nearby Watalgan National Park and state forests. Land clearing and fires were said to be the biggest threats to koalas in these areas.
Koalas are ‘thin on the ground’ in other parts of CQ where once they were common, for example, around Springsure, Tambo, Taroom and Emerald due to large-scale historical land clearing after the large-scale hunting of koalas in the early 1900s. Some long-term residents of these districts say they haven’t seen a koala for decades and blame drought and predation by dingoes. One of two rangers we interviewed, who has been engaged with bush heritage at Carnarvon Station, has never seen a koala in those parts and thinks they have not returned there because of
land clearing and predation. The other ranger saw a koala in that area in 2021 and added that
others have seen a couple too. One landholder reported regularly seeing healthy koalas on his property, midway between Emerald and Springsure, especially along creeks where the vegetation has not been cleared. His neighbours say the same. His property is almost 50% remnant, and he is doing more selective clearing
. This is also valuable to cattle, as it provides them with more shade, and cattle actually browse on brigalow as part of their diet. A First Nations elder of Country at Springsure has been witnessing the decline of the koala in that area since he was a child. He added that there were
heaps of koalas at Minerva Creek but over the last 30 years they’ve declined to almost nothing; just see a couple along the creek these days. He says
fires and tree clearing are the major threats. Dryer and hotter periods as a result of climate change are also linked to declines in these areas. Interestingly, in 2014 a property near Theodore was advertised for the enjoyment of seeing koalas; “Cattle creek frontage with gliders and koalas present” [
21]. An interviewee told us he often saw koalas between Biloela and Monto before he moved from the district in 1991. These koalas were mostly in ironbark, spotted gum and blue gum.
A property owner near Duaringa said koala numbers do drop after very dry spells and droughts, then they pick up slowly when it gets wetter. He has seen a few on his property along roadsides and fence lines, and where water is, when it gets very dry. His grandparents used to see a lot of koalas in this area many years ago, but said their numbers were decimated because of Chlamydia. They noticed lots of sick koalas at the bottom of trees. Chlamydia is still affecting koalas in this area, he said. One interviewee said he saw his first koala in the wild near Duaringa in the late 1980s (wintertime). He assumed the koala had been displaced because of significant tree clearing going on in the area. Koalas have also been sighted near Woorabinda. It was reported that when tree clearing was being carried out near Bauhinia about 30-40 years ago koalas were relocated to nearby bush and apparently the population persists.
Koalas are probably locally extinct close to Rockhampton and Yeppoon because of the combined results of hunting, drought, fires, habitat clearing and disease over many decades. However, several interviewees have indicated that the greater Rockhampton region, as well as in and around Rockhampton, was home to many koalas in the past. Historical documents suggest the same. A passage in
Scarlet Pillows, tales from a nurse from 1893 to 1898 [
22] (p. 17) says: “There were plenty of koalas about in the bush (next to the children’s hospital in Agnes Street on the Range) and some were curled up in our gate posts. These dear little animals chatter in a lamenting way, not like monkeys or opossums, but more like little children crying. When I first heard this, I thought that some of the children in the ward were whimpering but found them all quietly sleeping
”. Koalas were shot for enjoyment during excursions from Rockhampton to Yeppoon in the late 1800s as reported in the local newspaper. Near Jim Crow Mountain (now Baga) “a hapless koala is shot dead one evening” [
23] (p. 5).
A person who has lived at Cawarral, between Rockhampton and Yeppoon, for 45 years has never seen a koala despite a lot of searching. He did say that when he moved there, there were no trees whereas now it is lush with eucalypts. This tree clearing might have caused the decline of the koala there. Nearly all the interviewees resident in Rockhampton and Yeppoon say they have never seen a koala in the wild in those areas. However, one Rockhampton resident claims she once saw a koala in a tree in the suburb of Koongal about twenty years ago. She thinks it might have come down from the Berserker Ranges to the creek looking for better leaves during a dry spell. There have been some koala sightings since 2004, as well as evidence of scats and claw marks on trees, in the hills west of Mt Morgan. However, one interviewee said there were plenty of koalas in this area in the distant past. The landholder in this vicinity who we interviewed, and other interviewees, are concerned that wind farms are going in the wrong places and are destroying koala habitat through tree clearing in higher country.

In summary, the analysis has confirmed small koala populations persisting across some of CQ with generally good quality habitat, a message that must be clearly communicated to governments so that these populations are not neglected, and better conservation practices are put in place to ensure their protection and survival. Northeast CQ around Nebo, CCR, Sarina and St Lawrence are the areas with the largest koala populations according to the interview data, where they were described as plentiful and on the rise. The analysis also shows that after natural disasters koalas do return to areas (interviewees tell us this), but only if there is sufficient habitat, revegetation and the risk of threats are reduced. In western areas of CQ koala numbers appear to be on the decline. Some landholders are passionate conservationists who are actively bringing habitat back for the koalas. It was mentioned that koalas could be on land that will be developed, noting the need for better protection measures, caveats and honest consultants.
3.2. Perceptions of, and Attitudes Towards, Koalas
The landholders we interviewed predominately indicated that they
love their koalas and are
protective of them through leaving their habitat undisturbed. They like to know they have koalas and take pride in this knowledge. This fits with the idea that the koala is a flagship species for conservation [
24,
25]. Many landholders said they are concerned for the well-being of koalas on their properties and added that they
would not willingly destroy koala habitat. For example, a landholder who encountered koalas on his property near Duaringa during clearing operations purposely left those trees with koalas in them and a small number of other trees around them. A grazier from Mt Spencer said his dozer operator leaves different varieties and ages of trees for koalas. Another dozer operator, who cleared vegetation around Westwood (west of Rockhampton), always carried two hessian bags for translocating koalas to nearby properties. Apparently 40-50 koalas were translocated in this manner. This positive view of koalas can help their conservation on such properties and is evidence of landholders, in isolated cases admittedly, taking ownership of koala conservation. However, koalas in CQ have large home ranges and if other trees are destroyed then koalas still suffer. There seems to be more selective tree clearing going on now rather than wholesale clearing, although indiscriminate clearing was reported to still be taking place.
The graziers also perceive koalas as
no threat to their farm operations.
Koalas are not perceived as a pest nor an objectionable animal. Generally, koalas are not considered as competition to the operations of cattle grazing however, needing to retain habitat may be an issue for some. In contrast, other animals (native and introduced) like dogs, foxes, pigs and kangaroos are often hunted because they are perceived to ‘compete’ with farm operations. However, it is known that cattle have trampled koalas that are moving along the ground because the cattle see the koala as a threat [
26,
27,
28,
29].
Some graziers who are self-confessed conservationists said they have turned parts of their properties into nature refuges and graze cattle in a regenerative way in the hope more wildlife, including koalas, return. Often community members say that when they encounter a koala in the wild, it excites them and appeals to their sense of curiosity. Some landholders like to show ‘their’ koalas to children. One interviewee said that international students and tourists to CQ want to see koalas. Other perceptions exist that are less glowing, such as koalas can lash out with their sharp claws, are smelly and are not as cute and cuddly like the wombat.
In summary, the interviewees predominantly perceive koalas as loveable animals which they say they want to see protected. People are also sorry/saddened about the shooting of koalas in the past, which suggests they are glad those days have passed us and should never happen again. While they acknowledge the economic reasons for the fur trade, many view it as a national shame because of the alarming number of koala deaths that it caused, and the fact that populations have never recovered to even near those levels.
3.3. Threats to Koalas
A variety of threats to koalas were mentioned, most of which are well-documented in the literature. Firstly, road traffic is a significant threat to koalas in some areas as reported by interviewees, for example, along the PDH [
8,
17,
18] and around Nebo, Marlborough and St Lawrence. There were many reported cases of road traffic hitting koalas in these areas. A resident from Nebo is
shocked and surprised at the number of koalas killed by road traffic every day/night. The road kills also imply a relatively large number of koalas live in this area. The need for better protective roadside barriers is urgent [
30], but such fauna sensitive infrastructure is not always straightforward in saving koalas from vehicle strikes [
8,
18].
One landholder said fencing would be the only practical solution to allow koalas and human traffic to co-exist. However, the koala fencing bridge projects were too expensive to further contemplate fencing the entire PDH. The landholder wondered if corrugated iron has been suggested for fencing. Koalas cannot climb it and it is durable and used for fencing Australia-wide. She suggested that if you could engage the numerous local coal mining companies and enlist their moral and financial support, maybe you could encourage a donation program whereby the koala fencing project could be utilised as an 'offset' against their vegetation habitat obligations and/or emissions trading schemes. She added that no one who uses the PDH wants to endanger koalas. We simply must learn to co-habitat and be committed to make it work. This landholder would be happy to affix less expensive and less complex fencing to their already existing farm fences. This highlights a willingness of some landholders to contribute to koala conservation through fencing.
Literature suggests that fencing must be at least 5 km in length on either side of a wildlife under or over-pass [
31]. With koala habitat along the PDH being homogeneous and koalas basically getting killed or injured anywhere along that road [
18] and current fencing along the few existing underpasses being only a few 100m long [
25], a large financial investment is needed to extend these fences, or other innovative solutions need to be found.
Coal trains were mentioned as a significant threat by a property owner near Sarina. The mines themselves have also been major threats to koalas over the years as trees are cleared for mine infrastructure. As part of these operations, koalas were sometimes rescued and relocated to bush elsewhere. Dogs (wild and domestic) are a major threat but not considered a threat to koalas where there are ample habitat linkages (meaning koalas rarely must move along the ground for long durations) and/or where regular baiting is performed. Otherwise, wild dogs are said to be a major threat, and their numbers have got out of hand. It was said by one interviewee that a feral cat will take a young koala.
Native animals too were mentioned as threats to koalas such as dingoes, particularly in open country, and native birds. In the late 1800s landholders in the Duaringa district noted “we have seen them (wedge-tailed eagles) kill native bears
” [
32] (p. 257). This reference also notes a similarity between the Powerful Owl and First Nations people; “they both hunted Native Bear at night” [
32] (p. 258). However, research suggests that the impact on koala populations as a result of hunting by Indigenous people would, at best, have been minimal as their hunting practices were sustainable, the extent to which koalas were used varied across regions and between language groups and was subject to certain rules, and that the koala held great spiritual significance which can be traced directly to epic creation stories [
11,
33,
34]. Another example of wedge-tailed eagles taking koalas at Stanwell near Rockhampton is mentioned later in the section on translocations. One interviewee from a property at Clarke Creek recalls the first time he saw a koala there.
A mob of cockatoos was attacking a koala in a tree, that drew his attention. This was in the 1990s and he has seen several koalas along the creek since then. Another interviewee mentioned white cockatoos harassing a koala in a tree.
Wildfires were commonly said to be a threat to koalas. Even fuel reduction burns that are not done properly can be a major threat. A veterinarian raised the point that controlled burns sometimes cause deaths of koalas or severe injuries if the intensity of the fire is not properly controlled [
35]. This is a contentious issue which has important implications for fire management practices. Several landowners stressed the importance of fuel reduction burns, saying they undertake them, but also added that cattle help to keep fuel loads down. It is the country where the cattle do not graze (in the rangelands and thick forest) that can pose the greatest risk of wildfire. One elderly grazier noted there was too much paperwork to complete before you can get a permit to back burn on your property. Also, droughts and floods were mentioned as threats to koalas.
Chlamydia is said to be ever present and common amongst koalas in many areas, but not prevalent in the areas west of Rockhampton. A landholder with koalas on his property close to St Lawrence said he has seen evidence of
Chlamydia there since he was a child (in the 1950s). During an interview, Melzer [
26] stated that when koalas are stressed,
Chlamydia becomes more overt, and koalas can die as a result. While there is no direct established link between stress and
Chlamydia, it is known that chronic stress negatively affects the immune system and increases the likelihood of disease occurrence [
36] with the loss and fragmentation of habitat identified as a major stressor for koalas making them prone to outbreaks of
Chlamydia [
37]. However,
Chlamydia and injuries have shown to increase levels of stress in koalas [
38].
As anthropogenic climate change continues, areas in CQ are showing trends of becoming hotter and dryer. Consequently, koala populations are contracting eastwards and southwards. This has been more evident from the millennium drought of the early 2000s [
13]. A koala ecologist spoke about the dramatic decline in koalas around Springsure because of climate consequences like more severe droughts, heat waves and fires [
26]. Aquifers ran dry, then fodder trees would die [
39]. So, ground-water dependent trees are especially susceptible to climate change. Melzer [
26] said all the koalas at his Tambo study site died out due to the long drought that started in about 2011/2012 and lasted over a decade. Likewise, an interviewee from Tambo said
koalas used to be seen more frequently [when she was young]
but clearing of vegetation and especially drought have taken a toll. You might find the odd one along the river/creeks, especially during breeding time and possibly there might be a population out in the scrub off the Dawson Developmental Road.
Tree clearing is a serious threat to CQ koalas, but was more prevalent in the past, with more recent legislation helping to protect native vegetation. However, habitat reduction/fragmentation causes koalas to move further and more frequently, and they can face dangers such as vehicles and dogs when they do. The owner of a property at Nankin between Rockhampton and Emu Park mentions habitat fragmentation in the Yeppoon area where most blue gums are now gone from the creeks. Koalas have not been sighted in this district for many generations. When the linkages and complex layering in vegetation assemblages are removed, koalas are forced to the ground and become more exposed to predatory threats such as dogs. Likewise, fatal injuries sometimes emerge from fights between koalas when one moves into other’s territory. The frequency of such interaction is likely to increase as a result of a reduction in available habitat. An interviewee who lives in Yeppoon said we need more covenants to protect habitats and wildlife corridors. It was also reported that some graziers do not consider ironbark as eucalypts (and therefore koala fodder) and clear them.
Interestingly, some interviewees referred to the koala harvests (for the international fur trade) of 1906-1927 in Queensland [
40] and acknowledge that the loss of more than a million koalas during these years from both permitted and illegal harvesting would have decimated the population in their general area and that such numbers have never come back (
Figure 1). At the Rockhampton wharves bales of marsupial skins (possums and koalas) between the early 1900s and the 1930s fluctuated less than the more valuable bales of wool from the west or cotton from the Dawson Valley in later years [
41]. The fur trade was not only about the supply of fur for an export industry, but also a way for many people to survive in harsh economic times. Seasonal hunts would supplement a meagre income for the fathers or grandfathers of some of the people we interviewed. Even the Rewan Station
1 police employees, who were responsible for protecting the Carnarvon Gorge nature reserve, engaged in the hunting frenzy in the 1920s and justified their participation by citing low police salaries [
42].
Some landholders acknowledge historical wrongs in the treatment of koalas and, in parts, their habitat. In particular, several stories from interviewees mentioned their father or grandfather shooting koalas during the open seasons and feeling ‘bad’ or distraught about what they did, including suffering from nightmares after hearing the baby-like cries of the koala. For example, one interviewee told us that his grandfather had one day shot a female and unbeknown to him she had a joey. The joey started to cry, and his grandfather told him it sounded just like a human baby crying and that was the last koala he shot. Orphan bears crying like babies was mentioned by another interviewee. Even koalas that were shot cried like babies, and the experience left a lasting sad feeling for those that shot the animal. A 77-year-old man we interviewed explained how his father shot koalas between Yeppoon and Kunwarara during the Depression as an income. His father always had nightmares later about shooting them because they make a crying noise when shot. His father said there were koala bears everywhere in Yeppoon and surrounds at that time. We know there were a lot of koalas in the Yeppoon area in the first half of the twentieth century, but their numbers have not come back, yet koalas are present in low-density numbers in many other places in CQ. One interviewee said his grandfather shot koalas near Finch Hatton in the 1920s where the area was thick with koalas.
An older interviewee with a property 20 km south of St Lawrence recalled that his parents used to hunt koalas during the infamous open seasons. Another story passed down and told to us was about a man referred to as Silent Ted. It was said
he shot koalas out of season and then hid the illegal pelts in his tree house near Limestone Creek between Rockhampton and Yeppoon.
When police came out Ted would pull up the rope ladder and hide in the tree house atop a tall blue gum and stay there until they disappeared. The infamous tree house (
Figure 2) survived until 1947 at least [
44]. Another participant informed us that koala pelts were hidden in caves around Carnarvon Gorge in anticipation of the season reopening. It was also reported in the
Brisbane Courier [
45] (p. 15) “that the slaughter of the koala had been going on in the Carnarvon Ranges for some time, in anticipation of the opening of the season, and a heavy toll had already been taken”.
Many of the interviewees said after the hunting was finally banned koala numbers came back, but not to the same extent. Then disease went through populations about 50 years ago, decimating populations. Then about 15 years ago, populations increased. A similar observation came from a landholder with a property on the shores of Teemburra Dam near Nebo. She said soon after (the fur trade ended) Chlamydia went through and wiped them out because the population was still high, and their fodder was limited causing stress. Then they have slowly recovered.
Despite the pervasiveness of the fur trade in Queensland, there were groups at the time petitioning the government to protect the koala. In 1929 the Chairman of the Nature Lovers League wrote to the Minister for Agriculture with a summary of data surveyed from several CQ Shire Councils, Dingo Boards and Municipal Councils in 1928 about the impacts of the fur trade on koala numbers [
46]. The survey results largely indicated that “bears were practically exterminated or very scarce, and bears should be protected
” [
46]. The only local body not in favour of the protection of the bear was the Belyando Shire Council (Clermont) [
46]. Even earlier in 1908, according to one prominent landholder, comments from members of Shire Councils and Marsupial Boards in CQ, as well as from other landowners, were made suggesting the “government should protect the Native Bears for all time
” [
47] (p. 216).
In summary, according to the interviewees, the main threats impacting the survival of koalas across CQ are climate change, collisions with vehicles, tree clearing, disease, wild dogs, drought and fire (discussed below). CQ does not appear to be atypical regarding these ongoing and serious threats.
3.6. Translocations and Future Translocations
Some interviewees from Queensland islands spoke about the subject of potential koala translocations there as a survival strategy, which is a sensitive topic having both pros and cons. Two interviewees, who own large properties on Curtis Island, said they would like to see koalas reintroduced to the island if conditions were right. Such places might be able to become refugia for koalas. One of the landholders said his property has
plenty of ironbark, spotted gum and blue gum, species preferred by koalas. The Principal Ranger for the Southern Great Barrier Reef also agrees that there is potential for translocating koalas to Curtis Island with caveats about pest control programs being put in place. Koalas were once native to Curtis Island [
52] and were hunted there in the hundreds during the open seasons as well as illegally during closed seasons [
47]. On the other hand, an environmental officer who we interviewed does not think Curtis Island is suitable for koala reintroductions because it does not have sufficient habitat to sustain populations. He also advised that specific management programs are needed on the island to prevent large-scale fires, as well as saying that dog and other pest control programs would have to be adapted to accommodate the koala.
One of the traditional owners of Woppa, formerly Great Keppel Island, is in favour of koalas being translocated there again. However, he also said translocations should only be considered on the proviso that
sufficient quality habitat exists and that the koalas would have a very good chance of survival. Moreover, he stated that
better land and pest management would need to occur first. For example, rid Woppa of possums and goats before koalas could be reintroduced. Additionally, pet dogs should no longer be allowed on the island, and proper Indigenous burns should be carried out to prevent wildfires. While there is some speculation about whether koalas were native to Woppa, they were officially introduced there in 1928 as part of the restocking scheme [
52]. The Woppa traditional owner mentioned he has been told stories by both First Nations and non-Indigenous people about koalas once existing on the island. He thinks
they might have disappeared after possums were introduced and the competition for leaves wiped them out.
Historic koala translocations were undertaken in CQ, though it was rare for any of these koala populations to survive long-term [
52]. For example, in 1928, additional koalas (the exact numbers unknown, but typically these numbers were around 10-20) were translocated to “Keppel Island Sanctuary” (now Woppa) by Crown land rangers for the restocking of populations following the end of the koala fur harvest [
40]. Sanctuaries were proclaimed in an effort to protect populations of possums and koalas, especially in the 1920s [
40]. In October 1927, the Minister for Agriculture and Stock in Queensland announced that a scheme had begun for restocking districts denuded of their native fauna with fauna from districts where it was still plentiful [
40], explaining why these koalas were translocated to Woppa in 1928, possibly the first island in Queensland to receive koalas as part of the scheme. This did little for the koala population on Woppa though, because the last documented sightings of koalas there were said to have occurred in the 1960s during land clearing activities for resort style accommodation, then “the koala bears disappeared” [
53] (p. 24).
This observation corroborates another recollection by an interviewee who used to stay on the island in the early 1960s. At night we stay outside and quite often we see koalas run across the ground to get to another tree. Koalas used to be just there, don’t know how they got there. You only used to see one scarper across. Never seen a koala with a baby, we went there several times a year. Koalas looked healthy not sick; they were running around. It is a fairly big island, not a lot of trees. Much was cleared for cattle. We just saw them but didn’t know from where they originated. In our day koalas were reasonably common as were a lot of the birds that have all disappeared today.
Another example of a failed koala translocation came to light involving the Stanwell Power Corporation, just west of Rockhampton. In 2001 four koalas were released on a nature reserve near Stanwell Power Station as part of a trial. The nature refuge was in part established for the reestablishment of koalas (koalas were once abundant in this area and to recognise that fact Stanwell State School introduced Stanley the Koala as their mascot in 1998). The koalas were brought in from care and placed in an enclosure for at least two weeks. They were cared for by the volunteers, with supervision from a koala expert. After the initial holding period the gate was opened allowing the koalas to leave if they so wished. Daily feeding continued until such time as the animal stopped returning. Each animal was fitted with ear tags and a radio transmitter. Once the koala had departed the compound it was radio-located to ascertain its dispersal pattern. Four koalas were put through the system. Three were adults, one was a juvenile raised in captivity as an orphan. The three adults dispersed after a short period of residency around the compound. They left the local area and were lost to the study. The juvenile set up a small home range around the compound, slowly expanding the range over time. The animal was taken from the canopy by a wedge-tailed eagle during radio tracking and the volunteers tracked the signal to the eagle's feeding perch. The project was discontinued after that as the volunteers were disheartened [
54].
Koala distribution in Queensland is predicted to dramatically contract southward and to the coast over the next 50 years under a high global emissions scenario due to droughts and heatwaves [
55]. The National Recovery Plan for the Koala does mention conservation translocations as part of their strategic thinking [
55]. We acknowledge that
koala translocations to other places either as insurance populations, or as breeding populations for future return can be a contentious topic. Future translocations of koalas to certain areas such as Queensland islands as a strategy to ensure they survive is topical, but opinion is divided amongst participants. Some favour translocations but only if conditions are right such as enough food trees being present, while others are not in favour. Translocating koalas is a complex issue and requires research to see if it can be viable and sustainable. As we have seen in this paper, some past translocations of koalas have failed.
3.7. Other Key Issues
Some landholders say they feel threatened if knowledge of koalas on their properties gets back to government authorities because the presence of koalas might add to the restrictions on land clearing. As one landholder put it: most people are very wary of having people on their places to investigate koalas. They worry about the implications. Whether this is a fear based on fact or just a perception is unclear. A North Rockhampton resident with an interest in nature shared her perception:
I think farmers would be very secretive about letting the government know they have koalas. They would be very careful in what they said was going on because they wouldn’t want more restrictions happening on their properties. Which is quite sad because I think that is an educational thing. I think that they just perceive that the government will come in and try and control what they do. I don’t know whether it is a thing that would really happen. I just don’t know how you would ever change that mindset.
Another landholder who is concerned about potential controls on tree clearing said koalas may threaten their livelihood. He added there is limited trust amongst some landholders with the Department of Environment possibly becoming too heavy-handed. Therefore, several interviewees were secretive about koalas on their properties. Some landholders even declined to be interviewed because of this fear. A few interviewees do not like the idea that people can come onto their properties to check koalas out and then potentially introduce weeds. One interviewee said he had a bad experience when researchers came onto his property in the 1970s to catch and weigh koalas. He claimed, these activities stressed the koalas and as a result some died.
In short, some landholders do not want to admit to having koalas on their land even though we know that they are present. As mentioned, this is because they are afraid that governmental authorities may interfere with their land management, restrict what they can do on their land, take land off them or otherwise tell them what to do. Others are reluctant to talk about certain aspects of koala presence on their property or to go on record, and some opt to stay anonymous. Interestingly, more landholders who we approached for an interview declined the interview than gave an interview. However, some landholders are more proactive and openly koala conservation minded. These sentiments generally point to limited trust between landholder and government. Historically, farmers were forced to clear the land by government legislation, but now they are prohibited from clearing some types of vegetation, and they are looking for compensation. Some compensation is obtained by accepting off-setting funds from industry for the vegetation they do not touch on their land or from payments received to host alternative energy infrastructure on their land. Often this involves clearing of koala habitat, which can be problematic in addition to the land-use classification potentially changing from agricultural to industrial. There may also be in an issue with tenure of freehold land versus leasehold and what landholders are permitted to do with vegetation.
A few interviewees said watering points such as dams or troughs are used by koalas during extreme hot weather and droughts. They have encountered koalas going to drink or have seen them on the ground looking for water during very dry spells. One interviewee told us that a koala came to his camp site near St Lawrence every night to drink from a bowl of water that he left out. This was during a drought in the summer of 2005/2006. Confirmation of these encounters helps to build up a more accurate picture of koalas at times drinking free water. One interesting side note is that it is a popular theory that koalas do not drink water, but another interviewee said that his stepfather, whilst working on a property in the Dingo region during the 1990s, photographed a koala drinking from a puddle of water on a boundary fire break. Other interviewees also mentioned seeing koalas drinking water from different sources during droughts. One interviewee for example has seen a koala drinking from a dam. Koalas do not generally depend on free surface water, however, in areas of low rainfall koalas may be exposed to some water stress when their fodder trees are deprived of water [
56]. It is in such situations that individuals have been observed supplementing their water intake from other sources and it is suggested that in hot weather koalas need regular access to free water [
57,
58].

Large properties appear to have plenty of quality koala habitat, according to interviewees. This implies they are critical sanctuaries for koalas if fire and other threats can be managed, and tree clearing is minimised. Some of the landholders we interviewed across CQ actively plant eucalypts as part of revegetation goals. These people are passionate about trying to bring back koala habitat after decades of clearing. One of these landholders, with a property about 30 km west of Rockhampton (that had koalas in the 1930s) said that the younger families on the land tend to be passionate about saving koalas. He is also worried that wind farms will destroy valuable koala habitat (e.g. the proposed Boulder Creek and Moah Creek wind farms on land west of Rockhampton where koalas have been sighted up to fifteen years ago). A Nankin resident said, landholders with good intent are the regenerative farming people who have embraced the idea that putting trees and habitat back in the landscape is actually good for productivity. Koala populations have come back around the PDH, and this is because of good habitat that is being fostered and maintained by landowners.
In terms of the other key issues raised by the interviewees the main one is that some landholders are concerned about potential government interference/restrictions if they admit there are koalas on their property. Consequently, there is a need for an education program to allay these fears. Since most of CQ’s koala populations are on privately-owned landholdings, it is important that there are good relationships with those landholders in order to encourage conservation efforts that also do not jeopardise their ability to make a living. In many ways, the future of koalas lies with these landholders. Conservation action depends on positive partnerships, not on antagonism or alienation. As a society, we also need to ask landowners how we can help them to conserve koalas.
