Sydney: Australia officially listed koalas across a swathe of its eastern coast as “endangered” on Friday, with the marsupials fighting to survive the impact of bushfires, land-clearing, drought and disease. Conservationists said koala populations had crashed in much of eastern Australia over the past two decades, warning that they were now sliding towards extinction. Environment Minister Sussan Ley said she had designated koala populations as “endangered” to offer them a higher level of protection in New South Wales, the Australian Capital Territory and Queensland. The koala, a globally recognised symbol of Australia’s unique wildlife, had been listed as “vulnerable” on the eastern coast just a decade earlier. “We are taking unprecedented action to protect the koala,” the minister said, highlighting a recent government promise of Aus$50 million (US$36 million) to protect and recover koala habitats. Environmentalists welcomed the koalas’ new status but condemned Australia’s failure to protect the species so far. “Koalas have gone from no-listing to vulnerable to endangered within a decade. That is a shockingly fast decline,” said WWF-Australia conservation scientist Stuart Blanch. “Today’s decision is welcome but it won’t stop koalas from sliding towards extinction unless it’s accompanied by stronger laws and landholder incentives to protect their forest homes.” Conservationists said it was hard to give precise figures on koala populations in the affected eastern states. But estimates by an independent government advisory body — the Threatened Species Scientific Committee — indicated that koala numbers had slumped from 185,000 in 2001 to just 92,000 in 2021.
