I realise that all of these details are still just rumors etc. but still only recently here in Australia there has been reports that Disney had been looking at several peices of land in Sydney, Melbourne and Brisbane.
Aparently a smaller Disney park has been on the cards for Australia for a while now.
Most recently I heard rumors that Disney had been looking here in Brisbane at a rather large area of land right near Brisbane Airport. The Brisbane Governement is keen to sell alot of land off and together with the Gold coast council (home to Movieworld, Seaworld, Wet 'N' Wild, Dreamworld and White Water World) are continuing to try and secure more theme park type attractions for the area.
