The Australian Electoral Commission (AEC) has updated its advice on referendum expenditure, which includes donations.
Charities spending $15,200 or more on referendum campaigning or donations to organisations involved with the referendum must make a financial disclosure to the AEC.
Any eligible expenditure that occurs between 11 March to 14 October 2023 must be reported.
Disclosures must be made to the AEC by 29 January 2024.
The AEC has published guidance on its website about the referendum disclosure scheme.
