Hi Lizzie,
Based on your description the animal sounds more likely to be a Common Ring-tail Possum, Pseudocheirus peregrinus . The best way to confirm what species the animal is would be to send an image to Search & Discover; sand@austmus.gov.au if you see it again.
Thanks,

Hi Jan,
The holes sound more like the work of Bandicoots and even Kangaroos.
Thanks,

Antechinus do hop a little more than mice and rats, however the legs do not look like a Kangaroo's. The best way to confirm what species the animal is would be to send an image to Search & Discover; sand@austmus.gov.au if you see it again.
Thanks,

Thank you for your enquiry. The faeces or 'scat' of small carnivorous marsupials such as the Brown Antechinus do look different to those of a House Mouse under magnification. Visible on the surface of the Antechinus scat should be a variety of fragmented insect parts. The scat of rodents such as mice (which feed mainly on dry and fresh vegetable matter) is less defined and more uniform in colour. Like most native mammals Antechinus are often fearful of humans, however there are exceptions to this and I have heard of occasions where people and Antechinus live very close (and very happily) together.
