Pop princess Kylie Minogue has joined marriage equality campaigners in a last minute push to make sure as many people as possible are registered to vote in Australia's same-sex marriage postal survey.
Equality Campaign members took to city streets and university campuses across the country to encourage people to make sure they are on the electoral roll before tonight's midnight deadline.
Kylie, who once campaigned with former fiance Joshua Sasse to make same-sex marriage legal in Australia, joined the chorus of encouragement.
"Aussies! #loveislove & it's for everyone. Today is the final day to make sure you're enrolled. Don't wait!," she tweeted.
Co-chair of Australian Marriage Equality Alex Greenwich was on hand at a pop-up enrolling station in Sydney's bustling Pitt Street mall on Thursday to target hundreds of early morning commuters.
Many people were unaware of tonight's deadline, he said, but were motivated to enrol once they knew about it.
While most of the commuters said they supported same-sex marriage, others made it clear they would be voting no.
"We agreed to disagree," Mr Greenwich said.
Mr Greenwich said campaigners in the yes corner were spending the final hours before the deadline targeting the country's major thoroughfares, university campuses and social media encouraging residents to enrol.
The federal government announced their $122 million same-sex marriage postal survey earlier this month, to be run by the Australian Bureau of Statistics pending a High Court hearing in September.
As of Wednesday the Australian Electoral Commission had added 54,545 names to the roll since the announcement and made 577,879 updates.
