Question: Where does the the mountain pygmy possum found which is also the mainland Australia's highest peak?
Context: The western ringtail possum or Ngwayir is a possum found in a small area of Western Australia, regarded as a subspecies (Pseudocheirus peregrinus occidentalis) of the common ringtail possum, or as a separate species.  It is a small animal with dark greyish-brown fur without any rufous tinge, pale underparts and a long prehensile tail with a pale tip.  It is nocturnal and mainly arboreal, feeding on buds, leaves, flowers and fruit.  It breeds mainly in the winter, the single juvenile emerging from the pouch after about three months.  Its population seems to be declining, probably due to habitat loss and the introduction of alien species, and the International Union for Conservation of Nature has rated it as "endangered". Kosciuszko National Park covers 6900 km2 and contains mainland Australia's highest peak, Mount Kosciuszko, for which it is named, and Cabramurra the highest town in Australia.  Its borders contain a mix of rugged mountains and wilderness, characterised by an alpine climate, which makes it popular with recreational skiers and bushwalkers. The mountain pygmy possum ("Burramys parvus") is a small, mouse-sized (weighs 45 g ) nocturnal marsupial of Australia found in dense alpine rock screes and boulder fields, mainly southern Victoria and around Mount Kosciuszko in Kosciuszko National Park in New South Wales at elevations from 1300 to .  At almost 14 cm , its prehensile tail is longer than its 11 cm combined head and body length.  Its diet consists of insects (such as the Bogong Moth), fleshy fruits, nuts, nectar and seeds. Its body is covered in a thick coat of fine grey fur except for its stomach, which is cream colored; its tail is hairless.  On the underside of the female's body is a pouch containing four teats.  This possum is the only extant species in the "Burramys" genus.  It is also the only Australian mammal restricted to alpine habitat. The cinereus ringtail possum ("Pseudochirulus cinereus"), also known as the Daintree River ringtail possum, is a species of possum found in northeastern Queensland, Australia.  It was long believed to be the same as the Herbert River ringtail possum ("P. herbertensis"), but has recently been separated.  The two species differ considerably in appearance. The western pygmy possum ("Cercartetus concinnus"), also known as the southwestern pygmy possum or the mundarda, is a small marsupial found in Australia.  Genetic studies indicate its closest relative is probably the eastern pygmy possum, from which its ancestors diverged around eight million years ago. The pygmy possums are a family of small possums that together form the marsupial family Burramyidae.  The five extant species of pygmy possum are grouped into two genera.  Four of the species are endemic to Australia, with one species also co-occurring in Papua New Guinea and Indonesia. The Herbert River ringtail possum ("Pseudochirulus herbertensis") is a species of possum found in northeastern Queensland, Australia.  It is a dark brown to black species, sometimes with a white belly.  The Herbert River ringtail possum was long considered conspecific with the cinereus ringtail possum ("P. cinereus"), despite the fact that they are very different in appearance.  They are, however, the only members of their New Guinea-centred genus found in Australia.  The Herbert River ringtail possum is restricted to tropical rainforest from Mount Lee, west of Ingham, to the Lamb Range, west of Cairns. The green ringtail possum ("Pseudochirops archeri") is a species of ringtail possum found only in northern Australia.  This makes it unique in its genus, all other members of which are found in New Guinea or nearby islands.  The green ringtail possum is found in a tiny area of northeastern Queensland, between Paluma and Mount Windsor Tableland. Banksia" 'Pygmy Possum', formerly Banksia" 'Austraflora Pygmy Possum', and also known by its extended cultivar name "Banksia serrata" 'Pygmy Possum', is a registered "Banksia" cultivar.  It is a sprawling, very low growing coastal form of "Banksia serrata" (Saw Banksia), with very small leaves and small inflorescences. The Tasmanian pygmy possum ("Cercartetus lepidus"), also known as the little pygmy possum, is the world's smallest possum.  It was first described by Oldfield Thomas in 1888, after he identified that a museum specimen labelled as an eastern pygmy possum in fact represented a species then unknown to science.  The holotype resides in the British Museum of Natural History.
