Wasn't sure if this was an Antechinus (which has previously been recorded near to this location) or something else. Unfortunately these were the only 2 photo's captured.
Faint suggestion of a stripe on the face. Possibly a Dunnart, Sminthopsis sp., and if so probably S. murina. Best to wait for better photos before deciding. If you can get a white flash camera it will be a lot easier to ID small mammals, but white flash cameras are less common than the IR cameras.
