I would suggest that you keep in mind these ‘framework’ things about tax deductions:

Key Conditions:

You can claim a $120 million donation to charity as a tax deduction in Australia, provided the recipient is a Deductible Gift Recipient (DGR) and you meet specific eligibility criteria.

DGR Status: The charity must be endorsed by the Australian Taxation Office (ATO) as a DGR. General charity registration (ACNC) is not sufficient.
Minimum Amount: The donation must be $2 or more.

Genuine Gift: You must not receive any material benefit in return (e.g., goods, services, or event entry). Token items with no material value are acceptable.
Receipts: You must keep valid receipts or records for the donation.

Important Limitation: While there is no upper cap on the amount you can claim, your total deductions cannot create a tax loss. This means the deduction will only reduce your taxable income to zero. If your donation exceeds your taxable income, you cannot carry the excess forward as a loss to future years; the deduction is limited to the amount that reduces your taxable income to zero.

But, what would i know?
