The song became a huge world-wide hit in 2012 after the LGBTI community adopted it as their anthem.
Tony Wall, a man who played 10 games for the Western Suburbs Magpies in 1995, has started the petition.
“It will be very difficult to watch the NRL Grand Final with my wife and five young children as the event will be heavily politicised with a LGBTIQ anthem taking centre stage,” he wrote.
“My family and many other loyal NRL fans, who are No voters, will not feel comfortable watching the Grand Final when the NRL is imposing such a bold political stance on its fans while the issue is currently being voted on by the Australian people.
“Join with me in voicing your concern and demand that the NRL take a neutral position on the question of same-sex marriage.”
However, a tweet Wednesday from the NRL let the people know that he can sing whatever the hell he wants.
"He is actually singing all his biggest hits - as his fans would expect."
