$3500 USD.... would be close ? and ok if you lived in the US
but due to the aussie dollar arse, even at $2500 usd you'd never get you money back @ $3800 AUD plus shipping, customs, pissing about your in the $5k's
IF you stole it at $1500 the deal would be a worker. But that all assumes the bike is still in the US. However if its in Au give us ya number
