No; possums are arboreal, and there are not enough trees in the desert. Possums are most common closer to the coasts and in the mountainous regions, where there is plenty of bushland.
No. Koalas are found only in bushland along the eastern and southern coasts of Australia. They cannot live in the desert, as deserts do not support enough of the type of eucalyptus tree that koalas need.
