A same-sex marriage supporter has been caught hurling racial abuse at a 'no' voter as he filmed her pulling down “It’s OK to say no” signs from a Sydney roadside.

Video shows the young woman picking up signs at King Georges Road in Sydney's west and then telling the man filming her to "go back to la la la la la Arabland".

The footage posted on Sydney radio host Ray Hadley's Facebook page shows the woman swearing and demanding the remaining signs from the "no" campaigner as the pair argue on the edge of the busy intersection.

"Give me those signs," the woman demands as she moves on the man and grabs at the signs.

But the man, known only as Alan, refuses and replies: "You've done well, that will do.”

The woman repeatedly asks for the man to give her the signs and says she is not "threatening him" and she only wants the signs.

"You're double the size of me," she says.

Another "no" supporter arrives. The woman moves on while yelling racial abuse at the two men, telling him to "go back to la la la la la Arabland".

"You want to change our country, go change your own f***** up country, get the f*** out of ours.”
