Thousands of Australians were surprised to receive text messages from the 'Yes' Campaign, urging them to vote for marriage equality in the postal survey.
The message was sent from a phone user YesEquality and reminded recipients to check their mailboxes for the survey form.
"The Marriage Equality Survey forms have arrived!
"Help make history and vote YES for a fairer Australia. VoteYes.org.au.”
Many people shared the text message on social media, with some quite pleased about receiving it and urging their loved ones to vote.
Others though, were happy to vote yes but were disappointed by the SMS saying it was an invasion of privacy, as they hadn't given anyone their personal mobile number.
Alex Greenwich from the Marriage Equality campaign told News Corp Australia that they're currently using every resource possible to urge people to vote yes.
“This weekend thousands of Australians volunteered to door knock in their local area because they want everyone to have the same dignity and respect.
“The campaign is using every resource available to make sure fairness and equality are achieved for all Australians.
“The campaign has a responsibility to encourage every Australian to post their survey and we have done this through door knocking, media, advertising, social media and SMS messaging.
“It’s so important to reach as many Australians as possible and remind them this is a vote about fairness and ensuring every Australian is equal under the law."
Australians are being urged to post their postal surveys back to the Australian Bureau Of Statistics by November 7.
