Foreign interference through fake news spread on social media will be put under the microscope by a parliamentary committee.
The long-running inquiry will look at social media use designed to undermine Australia's democracy and values, including the spread of misinformation.
Other issues under scrutiny include:
* Responses to mitigate the risk posed to Australia's democracy and values by the government and social media platforms.
* International policy responses to cyber-enabled foreign interference and misinformation.
* The extent of compliance with Australian laws.
The upper house backed Labor senator Jenny McAllister's move to establish the Select Committee on Foreign Interference through Social Media on Thursday.
The committee's final report is due in May 2022.
