Thousands of Melburnians are expected to take to the city's CBD streets to rally for marriage equality with an AFLW player leading the charge.
Collingwood Football Club's Penny Cula-Reid will join activists from Equal Love to address the crowd at the State Library on Saturday afternoon.
Cula Reid is engaged to Mia-Rae Clifford, who plays for Melbourne in the AFLW, and the pair are the AFL's first publicly-known gay player partners.
"It's very simple. Love is love," Cula-Reid said in a statement on Friday.
"We all bleed the same blood, breathe the same air, regardless of race, religion, gender, age, sexuality or education, we are all equal and we should be treated as equal".
Equal Love says the Turnbull government is trying to bury the issue, which is why activism on the streets is as important as ever.
"Turnbull is hoping people forget that he has refused to challenge the right wing and Nationals who oppose civil rights for LGBTI people. But we won't forget," Ali Hogg, Equal Love Convenor said.
"We know that marriage equality could be a reality tomorrow if Turnbull allowed a free vote."
The rally will kick off at the State Library 1pm followed by a march to the Victorian Parliament.
