The northern brown bandicoot, a marsupial species, is a bandicoot found only on the northern and eastern coasts of Australia and nearby islands, mainly Papua New Guinea. It is not, however, found far inland.

The northern glider is a species of marsupial in the family Petauridae. It is endemic to Papua New Guinea, becoming known to science in 1981 after being discovered in the Torricelli Mountains. This species has been found in primary, mid-montane tropical moist forests. It is also known from rural gardens close to forest. The northern glider is Critically Endangered because its occurrence is less than 100 km2, all individuals are located within a single area, and a continuing decline of its habitat quality due to deforestation and human encroachment. They also face a major threat from hunting.

The striped possum or common striped possum is a member of the marsupial family Petauridae. The species is black with three white stripes running head to tail, and its head has white stripes that form a 'Y' shape. It is closely related to the sugar glider, and is similar in appearance.

The sugar glider is a small, omnivorous, arboreal, and nocturnal gliding possum belonging to the marsupial infraclass. The common name refers to its predilection for sugary foods such as sap and nectar and its ability to glide through the air, much like a flying squirrel. They have very similar habits and appearance to the flying squirrel, despite not being closely related—an example of convergent evolution. The scientific name, Petaurus breviceps, translates from Latin as "short-headed rope-dancer", a reference to their canopy acrobatics.

The Tasmanian devil is a carnivorous marsupial of the family Dasyuridae. It was once native to mainland Australia and was only found in the wild on the island state of Tasmania. It has now been reintroduced to New South Wales with a small breeding population. The size of a small dog, the Tasmanian devil became the largest carnivorous marsupial in the world, following the extinction of the thylacine in 1936. It is related to quolls, and distantly related to the thylacine. It is characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screech, keen sense of smell, and ferocity when feeding. The Tasmanian devil's large head and neck allow it to generate among the strongest bites per unit body mass of any extant predatory land mammal. It hunts prey and scavenges carrion, as well as eating household products if humans are living nearby.

The tenkile, also known as Scott's tree-kangaroo, is a species of tree-kangaroo in the family Macropodidae. It is endemic to a very small area of the Torricelli Mountains of Papua New Guinea. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss and by hunting. The tenkile is listed as endangered due to hunting and logging activities in Papua New Guinea. The tenkile is hunted for its meat, and is the main protein source for the residents of Papua New Guinea. The population of Papua New Guinea has increased in recent years due to improvements in healthcare; therefore increasing need in tenkile meat which means that more tenkiles are being hunted. Additionally, tenkiles are poached for their fur and are captured and sold as a part of the illegal pet trade. Domesticated dogs also hunt tenkiles. Deforestation in Papua New Guinea affects all tree-Kangaroos, however industrial logging that occurs in the Torricelli Mountain Range decreases the species' already restricted habitat. The Torricelli Mountain Range faces additional deforestation due to the timber industry, and the production of coffee, rice and wheat.

Tree-kangaroos are marsupials of the genus Dendrolagus, adapted for arboreal locomotion. They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, along with some of the islands in the region. Most tree-kangaroos are considered threatened due to hunting and habitat destruction. They are the only true arboreal macropods.

Goodfellow's tree-kangaroo also called the ornate tree-kangaroo, belongs to the family Macropodidae, which includes kangaroos, wallabies and their relatives, and the genus Dendrolagus, with eleven other species. The species is native to the rainforests of New Guinea, and the border of central Irian Jaya in Indonesia. Under the IUCN classification, the species is listed as Endangered, which is a result of overhunting and human encroachment on their habitat. It is named after British zoological collector Walter Goodfellow.

Other common names for this species include the black tree-kangaroo, the Vogelkop tree-kangaroo and the white-throated tree-kangaroo. It is threatened by habitat destruction and is listed as "vulnerable" by the International Union for Conservation of Nature.

The Wondiwoi tree-kangaroo is a mammal species in the genus Dendrolagus. It was known until recently from a single specimen which was collected in 1928. The only known specimen is a male weighing 9.25 kilograms (20.4 lb). D. mayri was located in the Wondiwoi Peninsula of West Papua at an elevation of 1,600 metres (5,200 ft) within montane forest. It is thought that the Wondiwoi tree-kangaroo could occupy an area of 300 square kilometres (120 sq mi). Global Wildlife Conservation, the wildlife conservation charity, lists the Wondiwoi Tree Kangaroo as one of their "25 Most Wanted Lost Species".
