If you're over 18 and a NSW resident, but think you aren't eligible to vote, you're probably wrong.
The NSW Electoral Commission said the 2017 Electoral Act prohibits people from voting on one condition - and they go to great lengths to make sure people have the chance to cast their vote.
"A person is not entitled to be enrolled to vote if convicted of an offence in NSW or elsewhere, and has been sentenced for that offence to imprisonment of 12 months or more, and is in prison serving that sentence at the time of the election," a spokesperson said.
Otherwise, regardless of circumstances, over-18 residents are entitled to vote.
"The Electoral Act 2017 doesn't prevent people from voting on the basis of unsound mind - so people are able to vote, no matter the mental disability they may have," the spokesperson said.
"We conduct visits to declared facilities - nursing homes, hospitals - so people can vote.
"We're doing about 600 mobile voting visits to declared facilities visits throughout NSW this year.
"Any prisoner serving a term of less than 12 months is eligible to vote - we send out postal vote applications for prisoners who may be eligible."
The penalty for not voting in New South Wales is a $55 fine. You must respond within 28 days of the issue date of the notice.
It's probably easier to just vote.
