THE marriage equality campaign has taken a new turn today, after many Australians received a text message calling on them to vote 'Yes' in the postal survey.
The text message that came from a phone user titled YesEquality read: "The Marriage Equality Survey forms have arrived! Help make history and vote YES for a fairer Australia. VoteYes.org.au."
Many shared the text on social media, complaining about it being an invasion of their privacy.
Others also left messages on the Marriage Equality Facebook page, asking them where they got peoples' private mobile phone numbers from.
Some social media users admitted they did not have a problem with the marriage equality campaign, and had voted yes.
But they thought that texting people and asking them to vote a particular way had crossed the line.
On the Marriage Equality Facebook page, one user wrote: "Received a text msg on my personal phone from you. I didn't give you my number. So why are you texting?"
Another wrote: "I would love to know who spammed my phone from your campaign? Especially since I am on the do not call register."
Is the 'Yes' vote SMS by marriage equality campaigners...
Others left messages saying the text message was seen as "spam" and claimed it could hurt the campaign.
Some users were more blunt, with one saying on Facebook: "Stop harassing me by text."
On Twitter, there was similar confusion among those who had received the text message.
Alex Greenwich from the Marriage Equality campaign told News Corp Australia in a statement that the marriage equality campaign is "using every resource available" in its efforts.
This also includes using SMS messaging.
"This weekend thousands of Australians volunteered to door knock in their local area because they want everyone to have the same dignity and respect," he said.
"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."
News Corp Australia has also contacted the Coalition for Marriage for comment.
