Mammals are divided into two subclasses based on reproductive techniques: egg laying mammals (the monotremes), and live birth mammals. The second subclass is divided into two infraclasses: pouched mammals (the marsupials) and placental mammals.
Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight[1] and Van Dyck and Strahan,[2] with some input from the global list, which is derived from Gardner and Groves.[3][4]
This is a sub-list of the list of mammals of Australia.
Conservation status listed follows the IUCN Red List of Threatened Species (v. 2013.2; data current at 5 March 2014[5]):
EX - extinct
EW - extinct in the wild
CR - critically endangered
EN - endangered
VU - vulnerable
NT - near threatened
LC - least concern
DD - data deficient
NE - not evaluated
