Identification of small mammals from photos is uncertain. It helps to have multiple photos, preferably with a scale in all images, showing: the ratio of tail-length to body-length; the nature of the ears, including how far the ear lobe will reach, in relation to the eye, when the ear lobe is folded forward; the pads under the hind feet; the fur above and below the body, any markings on the head or face; and the scales and fur on the tail.

Thank you. Yes it is climbing the fence. I posted it for amusement value. I know I shouldn't do that.

The photo by itself would be insufficient to distinguish between a large number of species of rodents in Australia. However, if these are fence palings about 1 cm thick, the animal is too big for Mus musculus (House Mouse); and in this location, i.e. an urban area in Canberra; and position, i.e. climbing a fence; we can discount all the alternative species other than Rattus rattus, therefore I will confirm.
