I just purchased this LED projector from Amazon and it does ship straight to Australia. It is only $50 cheaper than other US sites, but it is the cheapest I can find delivered to Australia. There are a few other models of this PB60G (base model), PB62G (wifi), PB63K (wifi/tv Korea Model) on ebay but all sell for over $600+.
You will need a US to AU Adapter to use this (or cord like this: http://bit.ly/19cty1Y). The voltage is fine as dual voltage from manual: 19.5 V , 4.62 A (Adaptor Input 100 ~ 240 @ 50 Hz/60 Hz)
UPDATE: TV tuner wont work in AU according to comment "the PB63U manual says that the tuner uses DVB-ATSC/TV-NTSC, which is incompatible with the DVB-T standard used for digital TV in Australia."

I received an email the other day from Amazon for $10 gift card when purchasing $50 gift card, so i purchased gift card then did my order (this will only work if you received the email directly from Amazon).
