Voters in the ALP-held seat of Sydney have been asked not to support the Labor Party while it refuses to allow same-sex couples to marry.
Australian Marriage Equality (AME) have begun distributing flyers to households throughout the electorate of Sydney highlighting Labor's support for the current ban on same-sex marriages.
AME National Secretary, Peter Furness, said that supporters of marriage equality are frustrated with the ALP's refusal to support full legal equality for same-sex couples.
"When it comes to marriage equality, Labor has ignored reasoned arguments, human rights' principles, overwhelming popular opinion and the heartfelt pleas of ordinary Australian families, but it can't ignore concerned voters in key seats", Mr Furness said.
"We are sending Labor a strong message that there is a price to pay for pandering to religious bigots and for opposing the equal human rights of gay and lesbian Australians."
In 2009 a national poll found 60% of Australians supported same-sex marriage while a Senate inquiry received an historic 11,000 submissions in favour of the Marriage Equality Amendment Bill.
The seat of Sydney has been held by Tanya Plibersek since 1998 and is considered to have one of the highest gay populations of any electorate in the nation.
"Given her electorate, Tanya Plibersek should be one of our strongest advocates but has chosen to rigidly toe the party line throughout her career", said Mr Furness.
"Targeting seats like Sydney is simply getting the Labor Party's attention in the only way left to us."
"Senior Labor figures have told us they will only take marriage equality seriously when they see constituents taking it seriously enough to change their vote."
"We are now following that advice."
