Here's my top 15 (couldn't get it down to 10, and can't order them) "new" films that were first shown in Oz in 2005. I realise the list could potentially look a bit odd to people from countries who are a little ahead of the Aussie's in terms of release dates.

2046 - Wong Kar-Wai (HK)
10e chambre: Instants d'audience - Raymond Depardon (FRA)
All Tomorrow's Parties - Yu Lik-Wai (CHI)
Cach - Michael Haneke (FRA)
Chats perchs - Chris Marker (FRA)
Darwin's Nightmare - Hubert Sauper (NET)
L'Enfant - Dardenne Brothers (BEL)
L'Intrus - Clare Denis (FRA)
Melancholian 3 huonetta - Pirjo Honkasalo (FIN) 
Last Days - Gus van Sant (USA)
Los Muertos - Lisandro Alonso (ARG)
Promised Land - Amos Gitai (ISR)
Shijie - Jia Zhang-Ke (CHI)
Sud pralad - Apichatpong Weerasethakul (THA)
The White Diamond - Werner Herzog (USA)
