My guess is that these are images, captured over different days, of a long-nosed bandicoot? I regularly see the conical diggings of them around this area, including recently. However - I could also be very wrong, and it could be a rakali (as near water)? Also - apologies for the image quality - I'm just playing around with wildlife cameras at the moment.
Asked Renee Brawata about this one who said "Im pretty confident that’s a Perameles nasuta, long nosed bandicoot, given the nose in the second pic and the paler underbelly"
