Australians must ensure they are enrolled to vote in the federal election before 8pm on Thursday 18 April.
Electoral Commissioner Tom Rogers said all Australian citizens aged 18 years and over were required by law to enrol and vote in the 18 May poll.
“Australians must also update their address details on the electoral roll if they have moved, or changed their name,” he said.
Anyone unsure of their status can check online via the AEC website or call 13 23 26.
“A record 96.5 per cent of eligible Australians are currently enrolled, which is an extraordinary achievement,” Mr Rogers said.
“At the same time, there are still people who remain unenrolled who need to take action before the deadline.”
The best and quickest way to enrol or update details is to visit www.aec.gov.au.
Australians unable to go online can pick up a paper enrolment form at any AEC office or Australia Post.
Australians turning 18 years of age on or before 18 May should also enrol and vote in the federal election.
