Google's plans to help people participate in the Voice

"This includes information about the referendum and how to vote, and prompts to go and vote on referendum day," said Longcroft.

Google’s election ads policies apply to any advertiser running ads related to the referendum, but to give Australians more information about paid election ads they see across Google’s platforms, Google also requires that any ad which mentions a political party, candidate or current officeholder for the House of Representatives or the Senate, is included in its political advertising transparency report, and that the advertiser is verified.

"We recently expanded our Political Content policy to extend advertiser verification requirements, in-ad disclosures, and transparency report inclusion for ads that feature or refer to a referendum," Longcroft said.

"One action we’re taking is collaborating with Australian Associated Press (AAP) to provide and distribute fact-checks to the 300 Australian news publishers that subscribe to its service," said Longcroft.

"Helping to ensure Indigenous journalists’ experiences are included in reporting has also guided our partnership with AAP, which is why we’re supporting the placement of two Indigenous trainees in their newsrooms."
