Here's my 10 best Oz films, in alphabetical order -
The Babadook (Jennifer Kent, 2014) This was the best Australian film released last year, as far as I am concerned (and criminal that it didn't get a higher profile on its release, but let's not go there), and definitely one of the 10 best.
The Boys (Rowan Woods, 1998) David Wenham is so good in this; menacing in such a quiet way (which is why Animal Kingdom is nearly as good and is in my top 20).
Jedda (Charles Chauvel, 1955) Somewhat melodramatic but important because it was the first local film to portray Aboriginal people as people and not as stereotypes.
Mad Max 2 (George Miller, 1981)
Newsfront (Philip Noyce, 1978)
Samson and Delilah (Warwick Thornton, 2009)
The Sentimental Bloke (Raymond Longford, 1919)
Sons of Matthew (Charles Chauvel, 1949) Like Jedda, somewhat melodramatic, but the first serious look at pioneers in this country (and light years away from the Rudds and the Hayseeds).
Wake in Fright (Ted Kotcheff, 1971) Where does one draw the line on what makes a film Australian or not? This outsider's view of us is more interesting - even devastating - than a local could or would have done (which is why it was so widely disliked when first released).
The Year My Voice Broke (John Duigan, 1987)
