best check it out for yourself. in broad terms this is how it works out
eg $200,000 profit - but only 50% taxable - ie taxable capital gain of $100,000. normal tax on $100,000 = approx $35,000. put $100,000 into super and get $100,000 tax deduction - and pay only $15,000 in tax
the proviso is as per minerva's post. might be worthwhile taking a year of work if the sums involved are substantial
