Now named Muggles, the small animal was discovered on a rock in the Australian outback before being taken to a vet in a four-day journey that included two flights.
The puggle was taken to Australia Zoo Wildlife Hospital in Queensland and is receiving specialised care.
It will be released back into the wild after six months.
Senior nurse and rehabilitation coordinator Vicky Toomey said: "Puggles are particularly difficult to look after, as they have different requirements to most other orphaned mammals.
"We don't keep them in the same manner as other marsupials as they naturally have quite a low body temperature, and they also feed infrequently due to long digestion times.
"Puggles of this size can take up to ten days to adjust to hand-raising and consume enough food to put on weight."
