This is a list of Australia-New Guinea species extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) and continues to the present day.[1]
The Australian continent is also called Australia-New Guinea or Sahul to avoid confusion with the country of Australia. The continent includes mainland Australia, Tasmania, the island of New Guinea, the Aru Islands, and other nearby islands. Australia-New Guinea is divided between three countries: Australia (mainland Australia and Tasmania), Papua New Guinea (eastern New Guinea), and Indonesia (Western New Guinea and the Aru Islands). Extinct animals from the rest of Indonesia are covered in List of Asian animals extinct in the Holocene. Species from the outlying islands of the country of Australia and the Bismarck Archipelago of Papua New Guinea are included below. The Solomon Islands archipelago, split between Papua New Guinea (Autonomous Region of Bougainville) and the country of Solomon Islands, is covered in List of Oceanian species extinct in the Holocene.
The fauna of Australia-New Guinea is very unique. Marsupials and monotremes also existed on other continents, but only in Australia-New Guinea did they out-compete the placental mammals and come to dominate. Aside from marine mammals, only two orders of placental mammals are native to Australia-New Guinea: rodents and bats. Dingoes and New Guinea singing dogs are considered feral dogs (Canis familiaris) introduced by humans.[2] The Christmas Island shrew is related to Asian shrews; no members of the order Eulipotyphla are native to Australia-New Guinea proper.
New Zealand species extinct in the Holocene are listed separately. The fauna of New Zealand is distinct from Australia-New Guinea. Birds, including numerous flightless birds, are the most important part of New Zealand's vertebrate fauna. Bats are New Zealand's only native land mammals.[3]
Numerous species have disappeared from Australia-New Guinea as part of the ongoing Holocene extinction, driven by human activity. Most Australian megafauna disappeared in the Late Pleistocene, considerably earlier than in other continental landmasses.[4] As a result, Australian Holocene extinctions generally are of modest size. Most extinctions occurred after the European settlement of Australia, which began with the First Fleet in 1788 CE.[5] [6] However, the thylacine, Tasmanian devil, and Tasmanian nativehen were extirpated from mainland Australia thousands of years before European settlement, although they survived in Tasmania.[7] The Norfolk swamphen and several New Guinea mammals also disappeared before European colonisation.

Mainland banded hare-wallaby | Lagostrophus fasciatus albipilis[29] | Western Australia | Not considered to be a valid subspecies by some sources.[30] | ||
Lake Mackay hare-wallaby | Lagorchestes asomatus | Between Mount Farewell and Lake Mackay, Northern Territory; possibly Great Sandy, Gibson, and Tanami Deserts | Also known as kuluwarri. The only known specimen was collected in 1932. Western Aboriginal Australians stated that it disappeared between 1940 and 1960. It was possibly driven to extinction by predation by feral cats and foxes, and changes to the fire regime.[31] | ||
South-western rufous hare-wallaby | Lagorchestes hirsutus hirsutus | South-west of Western Australia[32] | The south-western subspecies (L. h. hirsutus) is extinct. Two other subspecies survive: L. h. bernieri and L. h. 'central Australian subspecies'. | ||
Eastern hare-wallaby | Lagorchestes leporides | Interior southeastern Australia | Last specimen was collected in 1889.[33] The species was possibly driven to extinction by habitat loss caused by livestock grazing and increased summer wildfires after the end of native controlled fires in the winter.[34] | ||
Toolache wallaby | Notamacropus greyi | Southeastern Australia | The last confirmed records in the wild happened in 1924. Unconfirmed sightings happened in 1943 and 1950s-1970s, but extensive searching in the 1970s failed to locate any.[35] The last captive animal died in 1939.[36] | ||
Crescent nailtail wallaby | Onychogalea lunata | Western and central Australia | Last recorded individual was killed in 1956.[37] Extinction caused by predation by feral cats and foxes, and human-induced habitat degradation.[38] | ||
Christensen's pademelon | Thylogale christenseni | New Guinea | Most recent remains dated to 1738-1385 BCE. |

Desert bettong | Bettongia anhydra | Tanami Desert and Nullarbor Plain | Only known from one specimen collected in the Tanami in 1933 and subfossil material from the Nullarbor. The causes of extinction are presumed to be predation by feral cats and foxes, and changes to the fire regime.[39] | ||
South-eastern woylie | Bettongia penicillata penicillata | South-eastern Australia[40] | The woylie experienced a large reduction in population size and range due to extensive land clearing and the introduction of feral cats and red foxes. The south-eastern subspecies (B. p. penicillata) is considered extinct. The surviving south-western subspecies (B. p. ogilbyi) is critically endangered. | ||
Nullarbor dwarf bettong | Bettongia pusilla | Nullarbor Plain, Hampton and Mallee bioregions | Known only from subfossil remains but considered to have survived until European settlement.[41] | ||
Desert rat-kangaroo | Caloprymnus campestris | Channel Country and possibly southeastern Queensland | Last confirmed record in 1935 near Ooroowilanie, east of Lake Eyre, though several unconfirmed sightings were recorded in South Australia and Queensland between 1957 and 2011. It is considered to have become extinct due to predation by feral cats and foxes, though habitat degradation by herbivores could have contributed.[42] | ||
Broad-faced potoroo | Potorous platyops | From the Swan Coastal Plain to the Eyre and Yorke Peninsulas, and Kangaroo Island | Last recorded in 1875. Presumed to have become extinct due to predation by feral cats, exotic diseases, inappropriate fire regimes, habitat loss and degradation due to grazing livestock.[43] |

White-footed rabbit rat | Conilurus albipes | South-eastern South Australia, Victoria, New South Wales and eastern Queensland | Last recorded 1860-1862 in Victoria, where it was at one time common and even regarded as a pest, though a possible observational record was made near Deniliquin, New South Wales, in the early 1940s. It probably disappeared due to predation by cats, though human-induced habitat degradation could have contributed.[44] | ||
Capricorn rabbit rat | Conilurus capricornensis | Queensland | Known only from subfossil remains but considered to have survived until European settlement. Since there has not been a targeted survey for the Capricorn rabbit rat, there is a thin hope of its survival, although this is unlikely.[45] | ||
Lesser stick-nest rat | Leporillus apicalis | Arid and semiarid central Australia | The last two specimens were collected south of the Musgrave Ranges in 1933, and the last unconfirmed sighting happened in 1970 in a cave along Canning Stock Route. Considered to have become extinct due to predation by feral cats, possibly helped by habitat degradation caused by introduced grazers.[46] | ||
Bramble Cay melomys | Melomys rubicola | Bramble Cay, Queensland | Last recorded in 2009. Disappeared due to increasing storms that depleted the island of vegetation.[47] Its extinction was described as the first extinction of a mammal species due to anthropogenic climate change.[48] | ||
Short-tailed hopping mouse | Notomys amplus | From north-eastern South Australia and south-eastern Northern Territory to North West Cape | The only known specimens came from Charlotte Waters, Northern Territory in 1896. Subfossils indicate that it had a wide distribution in the central and western arid zone. Reasons for extinction are unknown, but could have been predation by feral cats and foxes.[49] | ||
Long-tailed hopping-mouse | Notomys longicaudatus | From north-western New South Wales to North West Cape | Last collected in Barrow Creek, Northern Territory in 1901-1902. Extinction attributed to predation by feral cats.[50] | ||
Big-eared hopping-mouse | Notomys macrotis | Western central wheatbelt of Western Australia | Last collected in 1843 near New Norcia. Considered to have been driven to extinction primarily by epizootic disease or predation by feral cats, with habitat degradation by sheep grazing as secondary factor.[51] | ||
Darling Downs hopping mouse | Notomys mordax | Darling Downs, Queensland | Known from a single skull purchased in 1846. Considered extinct because of predation by feral cats, with habitat destruction by agriculture and livestock farming as possible contributors.[52] | ||
Great hopping mouse | Notomys robustus | Davenport and Flinders Ranges, South Australia | Known only from skulls taken in old owl roosts.[53] | ||
Blue-gray mouse | Pseudomys glaucus | South-eastern Queensland and north-eastern New South Wales | Last collected with certainty before 1892. Extinction considered to have been due to habitat clearance, predation by feral cats and possibly red foxes.[54] | ||
Maclear's rat | Rattus macleari | Christmas Island | Last collected in 1901-1902. Became extinct after being infected by trypanosome carried by fleas hosted by black rats, which were accidentally introduced by the SS Hindustan in 1900.[55] [56] | ||
Bulldog rat | Rattus nativitatis | Christmas Island | Last recorded in 1897-1898. Became extinct after being infected by trypanosome carried by fleas hosted by black rats introduced in 1900. It was rarer than R. macleari and disappeared first. |

Norfolk thrush | Turdus poliocephalus poliocephalus | Norfolk Island | The subspecies became extinct around the late 1970s, with the last confirmed record in 1975. The cause of its extinction is attributed to a combination of clearing of native vegetation and predation by rats and feral cats. Additional factors were competition with introduced song thrushes and common blackbirds, as well as interbreeding with the latter species producing sterile offspring. | ||
Lord Howe thrush | Turdus poliocephalus vinitinctus | Lord Howe Island, New South Wales | Not recorded since c. 1924. Believed to be a result of the introduction of black rats following the grounding of the SS Makambo in June 1918. |

Plants and animals are listed as extinct and the federal level under the auspices of the Environment Protection and Biodiversity Conservation Act 1999. The Act lists all plants considered to have become extinct since the commencement of European settlement of Australia in 1788. There are 37 species currently listed as extinct under the Act.[94]
Of note, the species Pimelea spinescens subsp. pubiflora was presumed extinct after 1901, but a population was discovered in 2005.[95] The orchid Diuris bracteata was also considered extinct after its first collection in 1899, but it was thought to have been rediscovered in 1998. The later collections are now considered to be Diuris platichila.[96] [97] The spiny everlasting (Acanthocladium dockeri) was reclassified as critically endangered in 2006 after it was rediscovered in 1999.[98] Bennett's Seaweed, declared extinct under the EPBC Act in 1999; was the first protist listed as extinct by the IUCN in 2004.[99]
