Oh and "How To Make Gravy" by Paul Kelly
it's rare in that
-it's a good Christmas song
-it's a good Australian song
-it's a good Paul Kelly song
Kelly's actually really well-regarded an influential in Australian music, but I can't really enjoy many of his songs.
here's a live version of it. it's poor quality and that annoying noise is not usually in it. usually sounds more energetic too, I think.
