Hi Shaun,
Isn't it amazing how these TAB agencies operate?
You can't bet on Betfair in WA, and I just opened an account on TabOnline, the Queensland TAB, but they have such a rigorous requirement for the 100 point banking proof, that I nearly didn't make it. The reason being, that you have to be known to the referee for 12 months or more.
Having just moved about 250K from my old place, where I was known to all, maybe more than I wanted? LOL, I found it hard to get someone to sign the freeking papers.
I had no such problems with Betfair, just go to a Post office and present a few docs. and it's done electronically.
Good luck
