Enrol to vote before 8pm on Monday April 18, 2022 to be ready for the May 21 federal election day

Australians will have until 8pm tonight to update their enrolments via the Australian Electoral Commission website in order to be ready for the May 21, 2022 election date.

Since the election was announced last week, the AEC has processed 450,000 enrolments, with at least 50,000 of those being new enrolments.

Speaking with ABC News Breakfast earlier today, the AEC's commissioner Tom Rogers said a 'disinformation register' has been set up to counter any false information that may be circulating ahead of the election.

"We've seen an unprecedented level of conspiracy theories and other commentaries online," Mr Rogers said.

"It's been worrying, in fact, for the first time ever we've even established a disinformation register which people can access on our website."

Mr Rogers said there had already been some claims made online that "bordered on the unhinged".

So, every three years, Australia votes for a new House of Representatives. Also known as the lower house, this is where your local members end up once they've been elected.

It also votes for half of a new Senate because half of those sitting senators have come up for re-election, while the other half remain in their seats.

In order to call an election, the Prime Minister will visit Government House in Canberra to ask the Governor-General to dissolve the parliament and issue 'the writs'.

This is the formal instruction to the AEC to hold an election.

There needs to be between 33 and 68 days between the issued writs and the day of the election.

The AEC will then carry out a draw to determine where each candidate will appear on the ballot paper. The candidate that takes the enviable top position is said to have picked up the 'donkey votes'.

What is a donkey vote? It's when a voter numbers the candidates in the order they appear on the paper. It will still be counted because they have technically followed the voting instructions.

A donkey vote is not an informal vote, which is a vote that does not count because it has not followed the voting instructions.

For example, if the voter draws a flower (or something more explicit...) over the ballot paper, instead of numbering the candidates.

This kind of vote will be discarded and won't count towards the allocation of seats in parliament. It is, essentially, a wasted vote.

Avoid making an informal or a donkey vote on election day, and arm yourself with an informed understanding of who's running for your electorate.
