Yeah, AU ebay prices are mental.
I guess you can always extend your eBay searched to include the rest of the world (and people that offer shipping to Australia). All depends on how confident you are with buying from overseas sellers (I've never had any problems).
High Australian prices isn't a problem particular to eBay though.
My local bike shop is selling the Surley Steamroller frame for AUD$800 (US$635.80). Although Harris Cyclery sells it for US$410.

I love my local bike shop, and I -do- believe in supporting local business. But for AU$800 I could get a Bob Jackson track frame delivered direct to my door from the UK (which I think is what I'll be doing).
