The one from WWG won't work for you, I would think with a little research you could find one more local to you along the lines of the UBA suggested above. We have several members "in your area" of the world and it may just take a little time. In the meantime, maybe get a couple hundred in American money or add coin handling if it doesn't already have it. An issue with the BV you could run into, and I'm not sure if UBA's are susceptible to this, is that if Australian money is a different size than American money and you buy an American UBA with Aussie software then the money may not fit into the BV anyway. Definately something to ask whatever supplier about before purchasing the equipment.
One other thing about World Wide Gamings WBA setup, $289? Holy Crap! Sorry, but that's just ridiculous in my opinion. And I don't mean a ridiculously good deal. Besides that, I've never seen an S2000 where the BV needed it's own power supply. Looks like a earlier generation DBV-200 power supply
