Some people feel comfortable with ebay, I am less so. And will deal my physical precious metals through normal channels, especially since I have a direct account with the Perth Mint and can ring them to put in a buy or sell - and thus am not subject to broker fees.

When it comes to tax and the ATO I don't play games, it aint worth it. And I would recommend to all to properly account their income on their tax returns.

And yes there is capital gains on bullion like any capital gain.

CGT (Capital Gains Tax): CGT is applicable on capital gains made from Gold and Silver. This from the ATO:
A capital gain - or capital loss - is the difference between what it cost you to get an asset and what you received when you disposed of it.

You pay tax on your capital gains. It's not a separate tax, just part of your income tax, although it is generally referred to as capital gains tax (CGT)
