The Yes campaign for the Voice to parliament referendum garnered over $60 million in donations, eclipsing the No campaign's funds.

Australians for Indigenous Constitutional Recognition was the largest benefactor receiving $47.5 million, followed by Uluru Dialogues and Australians for Unity with over $11 million each.

Unidentified sources accounted for 21% of the total donations, totaling $79.6 million, sparking concerns over transparency and 'dark funding'.

High-profile donors included the Paul Ramsay Foundation, MYOB founder Craig Winkler, and ex-prime minister Malcolm Turnbull.

The Liberal Party's spending on the referendum was triple that of the Labor Party's, although both were outdone by the campaign's major groups.

Clive Palmer invested close to $2 million on a campaign opposing the Voice in the concluding weeks of the referendum.
