BTW, taxing income from gambling is very unclear. I've done alot of searching, and can't find an answer.

All the cases were for racing, and I was under the impression that income from racing was treated differently from sports/casinos.

The ATO has tried to make pro's pay before, but from what I can tell they weren't successful in any of the cases. Not sure how a real pro would hold up (who is organized, keeps very detailed records etc). If you were creative you could probally get out of it.

This is something I keep meaning to look more into, since if it's not taxable you really should let the ATO know how you make your money (unless you want them to assume you're a dealer).

If we do end up having to pay tax, there are easily ways around it but I'm not about to say it here.
