Five years jail and/or a $110,000 fine. He's very, very lucky to have been caught in Australia and not in Thailand! If caught over there he'd be looking at the Death Penalty or even a lifelong stay at the Bankok Hilton.
Reminds me of gangsters in the UK in the late seventies who realised the opportunity available when drug smugglers were sentenced to 3-5 years for importing millions of pounds worth of Hashish while local hardmen were doing 20 to life for robbing 10 grand from a bank.
