Well, I just learned that there are around 330 species of marsupials, with about one-third of those living outside Australia, many in South America. From red kangaroos to the long tailed planigale with a 3mm skull, there’s a variety of these creatures out there.
Although many do, not all marsupials have pouches.

Very rare white wallaby, Narawntapu National Park, Tasmania. They are not albinos, but have adapted to their beachside surrounds.

A joey inspects Mum's pouch, Narawntapu National Park. Really good place to see marsupials, to camp, swim. We caught a brief glimpse of a devil here too.

Like a miniature wallaby, pademelon are unique to Tasmania, and are happy to keep campers company at Narawntapu National Park.

Movement is the best sign of animal presence, making spotting koalas in the wild very difficult: they sleep all day. Furball here is at Healesville Sanctuary, Melbourne.

Kennett River, on the Great Ocean Road, is one of the best spots to see wild koalas. (I was probably snapping the cockatoo and didn't see sleepy in the trees.)

For a critter seen so commonly in the cities, I don't recall seeing many possums in the bush. This mother was in the Otways, on Victoria's Great Ocean Road.

Diprotodon, the most famous of Australia's megafauna, was a 4 metre, 2500kg wombat that went extinct 25,000 years ago.

At Simpson's Gap 18km from Alice Springs, keep your eye on the rocks for the black-footed rock wallaby.

Kangaroo and joey enjoy the shade at the campground of Nitmiluk National Park, also known as Katherine Gorge.

Not sure if that is a wallaby or a kangaroo actually. It is on the short Baruwei Loop walk from the campground in Nitmiluk National Park, NT.

At the break of dawn, a yellow-footed rock wallaby commands the high ground in the north of Ikara-Flinders Ranges National Park, South Australia.

We were told this spot near our campground was a reliable place to see these elusive critters. Previous shot also taken there.
