Thanks Andy,
I don't wish to sell an investment just to avoid paying tax on it, obviously the point of the investment is to make profit.... I guess the real question is "should i sell the shares, convert to cash, move to Australia and reinvest" so I can pay tax here on the profit and not in the UK and here... Interesting you say as a non-resident I wouldn't need to pay CGT, this obviously buys me some time to decide. I have yet to employ an accountant but am looking at $40,000 of profit on the shares.
