As every poster in this thread seems to have no idea of what’s gone on in Australia in a regulatory sense (even those that live and work there!!!), I hope I can shed some light on the situation for you.
Given that Australia was almost the first country in the world to ban online gambling over 5 years ago, operators in Oz (and indeed their employees) SHOULD be concerned about this very issue.
Let me walk you through it. The law passed in 2001 and is called the Interactive Gambling Act 2001. Basically it’s illegal for Australian companies to take bets from Australians, apart from lotteries and sports betting (sound kinda familiar?) The full act is here:

and a press release from 2001 summarizes it:
http://www.agimo.gov.au/media/2001/03/17430.html
So at the moment it’s enough to not take bets from Australians but there is a SPECIFIC part in the law that allows a country (such as the US) to request that the law include the taking of bets of people in the US (assuming the US has similar laws).
Here is that part:

Basically if/when the US bans online gambling it’s also the end of the road for Australian operators taking US bets. It’s MUCH easier than asking the Aus Government to enact legislation Professor – IT’S ALREADY THERE AS LAW!!!
Edit: I should also say that if the US asked really nicely right now for them to be included in this law (based on the wire act), the Aussies would probably say ok.
