GST It's the GST's third birthday, and it's still a winner for the Government

I think it might be an idea to celebrate the GST's birthday with a bit of an audit. The media have lost interest in it, but we all have to keep paying it and I get a steady trickle of letters from readers inquiring about its health and welfare.
Just how much money is it raising? How much of that money is going to the premiers as promised? Has it put an end to tax evasion? And, to put it bluntly, how many of the promises we were made have turned out to be "non-core"?
