Description

I was hoping this was an Australian Swamp Rat, but the white belly and pointy snout rule that out pretty well. Good climber, though.

Norway rats not known for their climbing ability, but it does look a bit that way. Long tail though.

Have you considered the Long-tailed mouse Pseudomys higginsi ?

Let's see, for native rodents, Parks Tasmania has:
Water Rat Hydromys chrysogaster
Long-tailed Mouse Pseudomys higginsi
New Holland Mouse Pseudomys novaehollandiae
Broad-toothed Mouse Mastacomys fucus
Swamp Rat Rattus lutreolus

Of those it's obviously not a Water Rat. Swamp Rat has tail 2/3 of body + head length, very small ears, and a short nose. New Holland Mouse is pink-tailed and not so large-bodied. Long-tailed Mouse: "lives mainly in Southern Beech rainforests where annual rainfall may exceed 2000mm... It is also found a little beyond the rainforest in dense, wet sclerophyll forests and deep fern gullies" which is nothing like this area of sea-level wetland surrounded by farmland. Broad-toothed Mouse has a tail shorter than head+body, dusky feet and belly, and is described with words like "tubby" and "chubby-cheeked."

So I don't think it's any of those. I've seen definite Brown Rats (they were huge) climbing around on power lines before, but I don't know how agile they are overall. I have a lot more photos of this fellow so I'll put up some better profile ones.

It was also quite unafraid-- these photos are with a small point-and-shoot with no zoom.

Found a bunch of things saying that Black Rats have tails markedly longer than their bodies, semi-prehensile tails, and narrow pointed snouts, so I'll go with that.
