Short description: none

This is a list of estimated global populations of Marsupials species. This list is not comprehensive, as not all Marsupials have had their numbers quantified.

Common wombat	Vombatus ursinus	7,000-8,000^[9]	LC^[9]	^[9]	It is widespread throughout the cooler and better-watered parts of southern and eastern Australia, including Tasmania, and in mountain districts as far north as the south of Queensland, but is declining in western Victoria and South Australia.^[9]
Southern hairy-nosed wombat	Lasiorhinus latifrons	70,000-130,000^[10]	LC^[10]	^[10]	It is widespread throughout Western Australia, southern South Australia, and south-western New South Wales. They live in semiarid to arid grasslands and woodlands. ^[10]
Northern hairy-nosed wombat	Lasiorhinus krefftii	230^[11]	CR^[11]	^[11]	It is one of the rarest land animals in the world and is native to the jungles of north-eastern Australia.^[11]
Koala	Phascolarctos cinereus	100,000-500,000^[12]	VU^[12]	^[12]	It is widespread throughout the eucalyptus forests of southeastern and eastern Australia.^[12]
Eastern Grey Kangaroo	Macropus giganteus	16,057,783^[13]	LC^[13]	^[13]	It is widespread throughout most of the eastern states of Australia, including Tasmania, in areas with more than 250 mm (10 in) of average annual rainfall. They are found in a variety of habitats, from semi-arid mallee scrub through woodlands to forested areas.^[13]
Western Grey Kangaroo	Macropus fuliginosus	2,790,358^[14]	LC^[14]	^[14]	It is widespread throughout the south-west Western Australia from south of Shark Bay to Laverton and the Nullarbor Plains.^[14]
Red Kangaroo	Osphranter rufus	8,542,148^[15]	LC^[15]	^[15]	It is widespread throughout the hot and dry deserts to open green-grass-lands of Australia.^[15]
Antilopine Kangaroo	Osphranter antilopinus	Unknown^{[citation needed]}	LC^{[citation needed]}	^{[citation needed]}	It is widespread across northern Australia in monsoonal tropical woodlands, and Common Wallaroos are found over most of Australia, especially around rocky outcrops.^{[citation needed]}
Tasmanian Devil	Sarcophilus harrisii	140,000^[16]	EN^[16]	^[16]	It is widespread across the island state of Tasmania. Their Tasmanian range encompasses the entire island, although they are partial to coastal scrublands and forests.^[16]
Thylacine	Thylacinus cynocephalus	0^[17]	EX^[17]	^[17]	It was once widespread throughout the dry eucalyptus forests, wetlands, and grasslands of mainland Australia. Indigenous Australian rock paintings indicate that the Tasmanian wolf once lived throughout mainland Australia and New Guinea. ^[17]
