You can offset your losses against income if the number of trades you do are over a certain threshold per year (but I don't remember the exact figure), you can then claim them as trading loss instead of capital loss. I did that in 2008 and 2009.
Can't recommend you my accountant though because she just does personal tax returns as a side job and for her personal friends only. I do know of an accountant in Melbourne who does tax returns for a couple of professional traders if you're interested, but I don't want to post details here. I was told he's expensive though.
