According to Preev.com BTC 280 = spot on $ 155,00 AUD or roughly $ 118,600 USD - in either case, given how quickly certain people are jumping in to make offers with out the usual asking to verify that the OP has the coins by asking for a signed message makes me think some PM's must have flown back and forth already?
*edit* didn't see this while I was typing...
If you prove ownership of those coins, the deal will be easier to settle.
