Gallipoli
Breaker Morant
Both deal with the loss of innocence in Aussie culture
Muriel's Wedding, Priscilla Queen of the Desert
You must see the Castle & The Dish
Eric Bana's " The Beast" if you like cars.
Anything by Peter Wier, i.e.: The Cars that Ate Paris, The LAst Wave, Picnic etc.
Babe & Babe 2, Red Dog, Young Einstein, Happy Feet if you have kids
Shine & The Sapphires are all excellent biopix
Baz Lurhman's style is a bit over the top, but I enjoyed Moulin Rouge and Australia
Have fun, there's something for you to do on cloudy nights
Cheers
Andy
