Haven't used them but just noticed this outfit: www.btradeaustralia.com Selling commission is ok, paid into your bank a/c - might be useful to some here if they're legit
You think that is expensive, Look at this mob. I don't know if it's Aussie based but they extort 'ahem' I mean sell here. at 10% off a high spot based on GOX.. https://www.spendbitcoins.com/buy/
Yes they're one of the oldest aussie btc sites around, if not the oldest. I actually got my first coins there. 10% is of course ridiculous but for me it worked out ok.
If anyone has a NZ bank account try bittrade.co.nz 0.5% trade fee per side, so has an orderbook. Cash deposits to NZ banks then instant withdrawls to any nominated account. Basic site, huge spreads and panic dumps/buys into ask/bids.
