How the surge in early voting will affect the election
The surge in voters casting their ballots early could mean we will have to wait longer for a result on Saturday night.
Some ballots cast early have a separate counting process, which could slow down the count.
And, like previous elections, the Australian Electoral Commission (AEC) will count a substantial number of pre-poll votes, but not all of them, says spokesperson Evan Ekin-Smyth.
"There are a range of different categories of early votes, which includes 'ordinary ballots', declaration votes cast outside an elector's home division and postal votes - all of which have separate counting processes," he told 9News.com.au.
"Ordinary ballots", which are cast within the electorate, will be counted at the same speed as ones cast on election day.

But ballots cast absentee need to be taken to the electorate, which means in a close race it could be a long wait.
Close to three million people had voted early in this election by today, nearly double the figure from 2016.
However, postal vote applications are not much different from previous years.
"As to the reason behind the number of early votes, the short answer is that we do not know," Mr Evan Ekin-Smyth said.
"We don’t ask people what specific thing is preventing them from attending on polling day.
"What we do know if that every electoral jurisdiction around the world that offers early voting is seeing a rise in the use of it."
