Thanks Beton, that's a very good idea.

CP you are right that it is utterly ridiculous for the ATO to tax winners they deem to be "business like". Every long-term loser need only produce a spreadsheet where they have balanced their accounts, and voila it's a tax right off. Problem is that they have taxed a few punters already. Say it's a 1% chance of happening to me - well I can handle a 3 month recovery time, but that 1% risk of being taxed is too much for me to stomach.
