There is much ‘talk’ about the number of koalas currently surviving in the wild throughout Australia. So many ‘experts’ have differing opinions: from less than 40,000 to over 300,000. This site will report the claims made my reputable sources. What is certain is that koala numbers have declined hugely in recent times to an alarmingly low level that extinction in the wild now seems inevitable unless meaningful human action happens. Now,


100,000-500,000 (300,000)  number of mature individuals | population decreasing (9.6.23)

“A recent expert-based elicitation process provided an aggregated mean estimate of 330,000 individuals across the Koala’s current range (McAlpine et al. 2012), suggesting the number of mature individuals is c. 300,000” (2012)  [from website 28.4.20, and 9.6.23 – no change ) link to article [last assessed May 2014 [bush fires and drought have surely taken it’s toll]


32,065 – 57,920 (9.6.23)

Koalas are in serious decline suffering from the effects of habitat destruction, domestic dog attacks, bushfires and road accidents. The Australian Koala Foundation estimates that there are less than 57,920 Koalas left in the wild, possibly as few as 32,065. You can see how we determined those figures here. (from website 9.6.23)

80,000 (9.6.23)

Sadly, our Aussie icon is experiencing a rapid population decline.  Millions of koalas once roamed our land, but today, there is estimated to be fewer than 80,000 left in the wild.  They are threatened by habitat destruction, car strikes, dog attacks, disease and drought.  They are considered a vulnerable species and are truly in need of our support.  Let’s keep these true-blue Aussies around for years to come! read info 28.4.20 [not updated as of 9.6.23]



36,000 in NSW (June 2020)

That following the 2019-2020 bushfires and the general trend of population decline, the current estimated number of 36,000 koalas in New South Wales is outdated and unreliable. Koala Populations in NSW report (June 2020)

no numbers  on website as of 9.6.23  [15,000 to 28,000 in NSW  |  5,000 – 20,000 South East Qld 28.4.20]

There is no widely accepted estimate of the total population size for Eastern Australia’s vulnerable koala population. Official information on this is poor, notwithstanding the efforts over decades of an army of passionate people from community, government, Indigenous, research and consulting sectors who
have studied this endearing species. There is a genuine need for better estimates of population sizes and trends. A compilation of the latest survey and estimate data presented here shows there are currently 37 to 38 metapopulations in NSW with a likely total population size of 15-28,000 animals. Southeast Queensland has a likely population size of 5,000 to 20,000 animals. read the article  

The World Wildlife Fund states that more than 480 million animals have been killed in the bushfires since September 2019. The WWF is concerned that the catastrophic fires are worsening the current “extinction crisis”. Its website highlights the Koala Triangle – from Noosa in Queensland to southwest Sydney and Gunnedah in the west of New South Wales – and expresses fears that in this region, the species could be extinct in as little as 30 years. read Coastbeat article (17.1.20) Nb as of 9.6.23 it still lists the Koala as ‘vulnerable’ in NSW, QLD, ACT


(329.000  estimate in 2016)

In 2016, experts estimated that there are about 329,000 koalas in Australia, which represents an average of a 24 percent decline in populations over the past three generations. “It’s very difficult to estimate koala populations, even at the best of times,” Adams-Hosking says, because they have a very wide range across eastern Australia, and are human-shy and found very high up in trees. “Some populations are becoming locally extinct and others are doing just fine.”  read article published 25.12.2019

50,000 – 100,000

“Australia’s total koala population has decreased from “millions” early last century to about 50,000 to 100,000, according to conservation groups. The decline was blamed on widespread hunting for the marsupial’s pelt, as well as introduction of diseases and the impact of development on natural habitats.” (posted 4.3.2015) Link to article



“Use of expert knowledge to elicit population trends for the koala (Phascolarctos cinereus): On the basis of estimates of mean population sizes for each bioregion and state, we estimated that the total number of koalas for Australia is 329,000 (range 144,000–605,000) with an estimated average decline of 24% over the past three generations and the next three generations. Estimated percentage of loss in Queensland, New South Wales, Victoria and South Australia was 53%, 26%, 14% and 3%, respectively.” (first published 5.1.2016) Link to article

“In addition to bushfires, habitat clearing, dog attacks and road accidents, between 2.5 and 3 million koalas were shot to supply the fur trade in America and Europe from the late 1800s to the early 1900s. In contrast to these astounding numbers, the current koala population is believed to be between 40,000 to 100,000 animals. (from website 1.7.17) Link to article

329,000 throughout Australia | 36,000 in NSW

“…all koala populations, bar a few in eastern Australia, are in decline. Some sharply so. So whether or not you find, as we do, the most recent estimate of 329,000 in Australia (36,000 koalas in NSW) to be optimistic one thing is clear: koala numbers are a fraction of what they once were and the species is slipping away….The best way to protect koalas is a tried and tested one. The scientists that identified the crisis ecoregion problem also identified the solution: large, well-connected protected areas. Only by protecting and connecting remaining koala habitat can the government enact meaningful conservation. Everything else is tinkering round the edges….” (posted 16.1.2017) Link to article
