Gay marriage supporters have come up with a hit list to win the hearts of 50 federal MPs.
A group of same-sex and heterosexual couples supporting marriage equality launched the "We're Waiting" at Parliament House in Canberra on Valentine's Day.
The aim of the campaign is to get 25 MPs to change their minds so that legislation legalising same-sex marriage can pass the lower house.
Ivan Hinton and Chris Teoh married late in 2013, before the High Court quashed the ACT gay marriage laws in January.
"It was (about) more than celebrating our relationship, it empowered people who I never thought would be empowered," a teary Ivan Hinton Teoh told reporters on Friday, adding their citizenship should not be segregated by the person they love.
"The people I grew up with, the kids who gave me a hard time at school, the kids who are now adults... have rallied behind me; these people from the small country town where I grew up, want marriage equality."
Australian Greens senator Sarah Hanson-Young said couples around the country would be popping the question today and she had one to pop to Prime Minister Tony Abbott.
"Come on; will you give your members the right to vote with their hearts?... Tony please say yes," she said.
