GAY families will intensify their campaign for marriage equality by taking their stories to Canberra next month.

Advocates from across Australia will launch the inaugural real families, real stories initiative today by posting their personal stories - about how not being able to marry has affected their family - on mymarriagestory.com.au

The Australian Marriage Equality campaign will be launched in Sydney this morning before families head to Canberra from October 12.

The organisation's national convener, Alex Greenwich, said the meetings with federal MPs would make them aware the issue did not just affect couples who could not marry, but also their friends and families.

"Friends will ask why their friend's lifelong partner is not and cannot be acknowledged the same way their husband or wife is," he said.

"Weddings are about love and commitment. They are beautiful events that in between our busy lifestyles bring family and friends together to celebrate an expression of love between two people."

Kim Burman, 27, and Jess Woolley, 25, will head to Canberra and speak to their local MP, Nick Champion, about their story living as a gay couple.

Ms Burman, of Munno Para West, said it was another step in educating people about how important marriage was for families and children.

"Every time we can get ourselves out there and start being seen as individual people instead of 'gay people', it's another step towards being more accepted in the community," she said.

"I have friends who have a three-year-old daughter and she has already piped up and asked why her two mums aren't married. She said all her friends' parents were married and asked why they weren't."

Ms Burman said children with gay parents were learning their parents could not be married because the Government said they "were not good enough".

"Kids as young as three have an understanding of what marriage is and how important it is," she said. "They learn their parents marry because they love each other and their children."
