At the bottom of page 69 of the 2020 Annual Report you can see the unrecognised tax losses - ~A$35.4m. Per the accounting standards a company is only allowed to recognise deferred tax assets (eg tax losses) to an extent that it is likely that there will be future taxable income against which these assets (losses) can be applied, or to offset any deferred tax liabilities. You'll notice in Troy's accounts they have fully offset their deferred tax liabilities with deferred tax assets.

So the tax losses should be ~A$35.4m + 2021's tax losses.
