maybe I am not interpreting your numbers correctly, but my understanding of ATO CG rules is that: - firstly you can use your capital losses (whether long or short term) to offset short term CG (<12 months) - then if you use residual capital loss (if any) to offset long term CG (>12 months) - then what is left is the capital gain prior to discount - then apply 50% discount rate to that to get the Discounted Capital Gain (which is then added to your other taxable income)
