Probably Perameles nasuta, not Isoodon obesulus, the only other bandicoot species recorded locally only in 2002 and 2003. Identification as Perameles due to white upper parts of hind feet. Longer ears of Perameles are not apparent - maybe torn off? Fur colour and tail colour also not diagnostic for Perameles - maybe due to wet and dirty condition? Ear measurement and various teeth and skull measurements can be used to distinguish these genera.
Yes please, if it is still there we can confirm the ID with confidence and maybe donate it to the ANWC collection. I am in O'Connor but can come out to wherever to collect it except I have a lunchtime meeting tomorrow. and a couple of things on Thursday.
