About 310,000 Australian Facebook users are set to find out their personal information may have been accessed by Cambridge Analytica.
The social media behemoth is expected on Wednesday (Tuesday US time) to notify the 87 million users worldwide whose data may have been unknowingly and “improperly” shared with the British political consulting agency.
About one in 50 Australian users and one in every three American users are among those affected.
Facebook users will receive one of two notifications at the top of their newsfeed.
