Good stuff MTR. Just one point though, you will be liable for Australian CGT if you sell those US assets, as an Australian tax resident. So yeah, more of a reason to hold on perhaps.
You pay 15% CGT in USA, however if I was to sell this would be credited back to me in Australia where I would then be paying Australian CGT.
If I eventually sell, this is just part of business, as a developer/trader in Australia I have to pay CGT every year at 30%, but it means I am making money and my third partner is ATO
