There have been quite a few threads over the past few months in the legislation forum which are Australia specific, you should check those out.
There should be some good bits and pieces there to start you off.
There are links to a government funded productivity commision report (you can google and find), which supported legalisation of ipoker. It took into account studies of problem gambling in the UK and other places.
There is also the argument that playing B&M means you have to play higher stakes away from the family home, etc.
EDIT: In particular there are some good things from FSL009
here and BruceN
