Yes, no problem. I am actually looking to trade mine for some of my wanted items. I would probably not sell for less than $400, but I have no idea what the going rate in Australia is.
You can check out US eBay sales the last 6 months and see a few have sold.
If you do have a trade or purchase in mind, I do not mind bringing it with my to Sydney and mailing it within Australia, which I would assume would be cheaper, but have no idea really!
