All i know is that my boss, my friends, and some of my acqaintences do it. You need to set up a self-managed trust, but otherwise it's just like normal super. You can contribute more than the minimum requirements, but same laws and tax for withdrawing early apply. I may be wrong, so check with more knowledgeable persons. Also, you need a minimum of around 40-60k to make establishing one actually worth while apparantly. Age might make a difference there.
Shouldn't be more than 1000 or 2000 to set up a trust and super retrieval / rollover, but that's an educated guess.
Most places that do it offer consultations for free.
