Photo initially looks to be a Kreft's Glider (Petaurus notatus) but known Squirrel Gliders (Petaurus norfolcensis) are present on the site. Kept at Petaurus sp. just in case it's a juvenile Squirrel Glider
Hard to be sure from this description and photo. But it is not a Bandicoot, Potoroid (not known from that area anyway), Hare, Rabbit, Broad toothed rat, Rattus species, Brush-tailed Possum, any kind of glider nor a juvenile of any kind of ungulate found in Australia. Only two species in the region have part of their tails white and it is not a Rakali. So I agree with David Cunningham that it is a RTPoss.
Unlikely to be a Rakali at that location and the long rear legs don’t match Rakali. Ringtail Possums can have white tips on their tails, which are not brushy, so that is a possible ID.
