interesting suppositions chappy. happy for you to play with numbers.
It may be better to look at an example that compares tax paid for each year of owning a property and the year when disposed of. If you claim depreciation each year the amount claimed reduces the cost base when you sell. Unlike other costs like agents selling fees which increase the cost base.
So there is an interaction between how much tax you pay, the tax brackets at the time, your ordinary income amount and whether you can make a tax deductible contribution to super which would reduce your taxable income but the super contribution is taxed in the fund(usually 15% tax rate)
