List of Australia-New Guinea species extinct in the Holocene

[3] Numerous species have disappeared from Australia-New Guinea as part of the ongoing Holocene extinction, driven by human activity.

The study argues that the western long-beaked echidna survived as a rare species in Kimberley into the 20th century based on the circumstantial improbability of a collection label misassignment, the uniqueness of ectoparasites found on the specimen, the similarity of some Kimberley forests to known habitat in New Guinea, and the testimony of an Aboriginal elder.

[13] Additional research such as ancient DNA, stable isotopes, and trace elements may shed more light on this specimen, and targeted studies of relevant Kimberley Pleistocene and Holocene subfossil assemblages would be worthwhile.

[19] The extinction of the thylacine in mainland Australia was likely caused by competition with human hunters and dingos, while in Tasmania it was deliberately exterminated by sheep farmers.

[15] Plants and animals are listed as extinct and the federal level under the auspices of the Environment Protection and Biodiversity Conservation Act 1999.

There are 35 taxa "presumed extinct" as specified in Part 4 of Schedule 1 of the New South Wales Threatened Species Conservation Act 1995.
