Polls are opening, barbecues are being lit, eskies are being filled, and coffee machines are being warmed up - it's election day in Australia. As you head out to cast your ballot, Melissa Clarke and James Glenday take a look at what we've learned throughout the campaign. Australia Votes will return tomorrow to pore over the election results. You can hear more analysis on the election campaign from This Week with Linda Mottram. Tonight, the ABC's election night radio coverage begins at 6pm EST, with Sabra Lane and Rafael Epstein taking you through the results. You can hear it live on the ABC listen app. Tomorrow, Sabra Lane will return with a special edition of AM, and a Sunday episode of ABC News Daily with Sam Hawley will be analysing the outcome of the campaign. And on Monday, Patricia Karvelas and Fran Kelly will host a special episode of The Party Room.
