Voting 101: what is preferential voting and how does it work in Australian elections?

Australian citizens vote for their local member of parliament to sit in the House of Representatives via a preferential voting system. How does that work and how is it different to the US and UK 'first past the post' systems? In Guardian Australia's Voting 101 series, Matilda Boseley explains everything you need to know about the 2022 federal election. Watch out for the next episode, where Boseley explains how proportional representation works in the Senate. • This video was amended on 24 April 2022 to make clear that in order for voting papers to be valid, all candidates need to be numbered.
