There are a few good australian movies it's just that most of them are limited release in australia only and don't make it to the US. however, a lot of our good actors go to hollywood.
Here is a list of some good aussie films:
Gallipoli - This is an excellent war film, with a very emotional ending...one of my favourite mel gibson films.
The Devil's Playground - This is an older movie (70's I think) but it stars a young Simon Bourke.
Priscilla, Queen Of The Desert - Not my type of movie but it is quite popular.
Rabbit Proof Fence - really good movie.
The Proposition - really good, you should check it out if you liked Ned Kelly.
The Castle - I think you need an Australian sense of humour to understand this movie.
Wolf Creek - a bit scary
Others include Somersault, Shine, Kokoda, Lantana, Little Fish, Jindabyne, Looking For Alibrandi (good coming of age movie), Murielles Wedding, Strictly Ballroom...And then theres Baz Lurhmans movies like Romeo + Juliet or Moulin Rouge...I am really looking forward to his upcoming movie about the bombing of Darwin (http://www.imdb.com/title/tt0455824/). And movies shot in Australia include Babe & Mad Max.
Haha I haven't seen Kenny as yet. Ten Canoes is excellent, a very interesting film. I have definitely grown more fond of Aussie films in the last few years, I was never really into them that much.
It's a Geoffrey Rush thing, you wouldn't understand!
