Are you asking how much tax you have to pay? If you have held the shares for over 12 months you are subject to capital gains tax (CGT). Basically your total sales proceeds (e.g. 1.75*# of shares) minus your cost base. Take that number divide it by two and add to your assessable income.

If you held for under 12 months then the entire profit is subject to tax and is added to your assessable income.

There is no distinction for holding for 8 years or just over one year.
