Here are all your questions answered.
When do polls close on election day and when does vote counting begin?
Counting of ordinary votes begins in each polling place immediately afterwards, along with the counting of House of Representative ordinary votes taken at pre-poll voting centres.
How does it work?
The AEC views election night as the “halfway mark” of the federal election, that will see approximately 20-25 million ballot papers counted in what’s called an indicative count.
The House of Representatives count
“The TCP count is a mandatory requirement and is conducted to give an early indication of who is most likely to win each seat, as this is not always clear from first preferences.”
The Senate count
After election night, Senate ballot papers are packaged and delivered to central AEC counting centres where first preferences are re-counted. They are then re-packaged and sent to the Central Senate Scrutiny (CSS) site in each state and territory.
When will we know who wins?
“That’s our declaration test — the mathematical impossibility we have to meet before we can declare a seat. That doesn’t happen on election night. In fact, it won’t happen the day after either. It typically happens in the days and weeks post election.”
What happens after election night? What about Sunday?
Postal votes must be received by the AEC by Friday 3 June to be included in the vote.
The AEC says it’s guided by the principle of “right, not rushed”.
How does the AEC ensure the integrity of vote counting?
Then, there are additional layers of scrutiny through its mandatory secondary count, verification and security checks.
How many seats does a party or coalition need to win to form government?
This means Labor would need a net gain of seven seats as the Coalition seeks to retain or increase its own haul at the upcoming poll.
