Hi Sue,
We get these in Canberra also. A good place to check for species identification is Canberra Nature Map, which has a species list that includes photos you can browse.
This moth is Gastrophora henricaria, Fallen-bark Looper, Beautiful Leaf Moth -

I wonder if anyone can identify this underwing moth from Brisbane. My searches have been unsuccessful.
