* No accurate census: Koalas are difficult to count due to their solitary nature, vast range, and the challenges of tracking them in dense forests.
* Population fluctuations: Koala populations are constantly changing due to factors like habitat loss, bushfires, disease, and drought.
However, here's what we *do* know:
* Estimated numbers: Estimates for the total koala population in Australia range widely, from 50,000 to 100,000.
* Declining populations: Unfortunately, koala populations have been declining in many areas.
* Endangered status: Koalas are listed as "vulnerable" under Australian law.
If you want to stay up-to-date on koala populations, I suggest checking reputable sources like the Australian government's Department of Agriculture, Water and the Environment, or the WWF Australia.
