i would ignore Kacy's advice and everyone else's (apart from Mistyrains)
for a share trader, the non-commercial loss rules are irrelevent, unless your non-share trading taxble income (including fringe benefits, personal super contributions & investment loss) is $250,000 per annum or more
Kacy has misunderstood the 'income test', which is sales turnover (assessable income) less than $20,000 [rather than net profit less than $20,000]
