Air Asia are currently doing this promo:

Travel Period : 1 August 2011 - 31 October 2011
- Advanced booking required.
- Fares are not available during embargo period.
I was looking around the net and there aren't any cheaper fares to Australia. I have searched for flights in October and got for £451.
There are also good deals to other destinations such as Singapore or Bangkok all around £350.
Hope you guys can make use of this deal. 3 days remaining until it closes so be quick.
Best wishes and Happy Easter.
