You can declare a loss by making an off market transfer to another person "someone you trust" then that loss will offset your your capital gain. You can also apply to have multiple financial years worth of tax returns (capital gains ans losses within 5 years) to be considered symultaniously. This way your capital loss this financial year can be used to offset your previous capital gain. You should set the sell price to just offset all your losses so the buy price is maximiumed for when trading resumes (minimizes capital gain when you/your friend selks)
