BREAKING NEWS: Tiny NSW Rally Against 'Sick' Gay Agenda

The group that organised the VOTE NO skywriting campaign have foreshadowed another event at a fiery rally against gay marriage in Sydney.

A stone's throw from where thousands watch Sydney's famous Mardi Gras floats go by each March, about 20 same-sex marriage opponents have rallied.

Police and counter-protesters easily outnumbered attendees of the Straight Lives Matter rally at Green Park in Sydney's Darlinghurst on Saturday.

"My grade 3, one-man production of 'Sophie's Choice' drew a bigger crowd," comedian Joel Creasy posted on Facebook.
But one of the rally's speakers appeared unperturbed and promised similar stunts to the controversial "VOTE NO" skywriting above Sydney last week.

Cat Clayton was introduced to the crowd as the woman who had helped organised last Saturday's sky message.

"We do have something happening, so keep your eyes on the skies," she said.

"Any day in the next few, I hope."

The rally was organised through social media in connection with the far-right nationalist Party For Freedom.

PFF member Toby Cooke urged his supporters 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," he said.

A police line separated the opposing groups who levelled verbal abuse at each other.

Counter-protesters led gay pride chants and waves rainbow flags on the other side of Green Park.

Some counter-protesters said PFF chose the park because of its proximity to the Gay and Lesbian Holocaust Memorial and St Vincent's Hospital, which led the fight against AIDS in Australia.

Equality Campaign co-leader Alex Greenwich, who spent the day doorknocking homes to talk about the postal survey, said he wouldn't "be distracted by the actions of 20 people".

"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 told AAP.

The ABS advises any person who has not received a postal survey by Monday to contact them.

Responses are due back by November 7.
