Australians vent fury online after getting unsolicited same sex marriage texts

People across the country have voiced their outrage after text messages were randomly sent to phone numbers urging the recipients to "Vote Yes" in the same sex marriage postal survey.

Unsolicited messages were widely sent by "YesEquality" on Saturday, asking people to "Vote Yes for a fairer Australia".

Recipients were urged to "Help make history" and directed to the Equality Campaign's website.

Many took to Facebook and Twitter saying they felt "violated" and questioned how their phone numbers were obtained.

"Excuse me but did anyone else get a 'vote yes for marriage equality' text message?" one person asked on Facebook.

"How did they get my phone number? I feel violated," they wrote.

Another wrote that the message was a form of "Bullying" by the LGBTIQ community.

"How dare they force their opinions on me," she wrote.

"I'll be contacting the telecommunications ombudsman and the privacy commissioner to complain about this invasion of my privacy," a third said.

While admitting it was an odd message to randomly receive this morning, another woman called the tactic "Weird, but cool!"

The Marriage Equality Campaign says it was a computer generated message and no private information has been used.

In addition to the texts, both sides of the same-sex marriage debate ramped up their campaigning today with rallies and door-knockings among the other mediums used.

Thousands rallied through Brisbane for the annual pride festival while "yes" campaigners doorknocked tens of thousands of homes across the nation.

Meanwhile, a smattering of same-sex marriage opponents gathered in Sydney's gay heartland while preparations were made for the Coalition for Marriage's Victorian launch.

Melbourne campaigner Cella White - accused of falsely claiming her son was told he could wear a dress to Frankston High School - is expected to speak at the CFM event on Saturday night about the abuse she has received since appearing in the group's anti-gay marriage ad.

Equality Campaign co-leader Alex Greenwich has urged supporters not to get distracted by those who "throw red herrings".

Mr Greenwich, who is a NSW MP, urged supporters of the Yes campaign to focus on the task at hand.

"It is so important for the marriage equality campaign that we do not get distracted by the people who are always trying to throw red herrings," he said.

He said he was heartened by the feedback from same-sex marriage supporters involved in the door-knocking campaign and said there was strong support "across all demographics, all ages".

On the other side of the debate, about 20 people turned out for a rally dubbed Straight Lives Matter rally in Sydney's LGBTIQ heartland, Darlinghurst.

Organised by a group of self-described patriots, one of the speakers urged people to push back against the "sick and vile homosexual agenda" in Australian schools and universities.

"No amount of surgical mutilation by some dodgy surgeon in the Philippines can make you a woman," Toby Cooke said.

Australian Christian Lobby chief Lyle Shelton, and Keith Mills, the leader of Ireland's unsuccessful No campaign, are expected to address the Coalition for Marriage in Melbourne.

CFM has this week been holding meetings across Australia to convince voters to reject a change to the legal definition of marriage.

The result of the voluntary postal survey on same-sex marriage is due on November 15.
