I haven't seen much.. but my favourite Aussie flicks are...
The Castle (classic, and I still am not sure I get all the jokes).
Crackerjack (yeah yeah, Mick was alright in this)
Hercules Returns (Great when under the influence of certain substances)
The Nugget (eh.. not bad.. but I can't think of other Aussie movies and can't be stuffed going through Ella's (huge) list
)
I've seen a movie called "something" Beach.. and it was pretty much about some chick who rooted w/ a lot of guys on the boat.. in the water.. on the beach.. wherever. I saw this on channel ten after only living here for a couple months.. really warpped my view of Aussie beaches (and I went to them more often heheh).
