This glider's behaviour was unusual - it was out in the daytime, initially appeared to be eating small stones on fire trail and slightly dazed. It wasn't afraid when I slowly approached it. Currawongs were keeping a close eye on it. Could it have been plucked from a hollow by a currawong then dropped? Could it be an escaped pet? It then appeared to recover from its dazed state and scampered up a tree, only to be severely harassed by many currawongs. Although it escaped to a bushier tree I'm unsure it would have survived after that.
Upon seeing the Extra pics on Facebook I’m inclined to agree that this is a Kreffts vs a Squirrel. Lizette would you mind incorporating the extra photos here.
