Footy codes back marriage equality in ad

Australia's major football codes will openly declare their support for gay marriage by featuring in a national media advertisement under the hashtag #TeamEqual.

The AFL, NRL and Football Federation Australia will attach their logos to a full page ad featuring former league player and coach Paul Langmack, who represented rugby league as part of the Anti-Homophobia in Sport float at Sydney's Mardi Gras in March.

"On and off the field we support and stand by our mates," the ad reads.

"These sporting codes unanimously stand for fairness, believing all Australians should be treated fairly and equally in the eyes of the law."

The ad will appear in the Weekend Australian magazine, on sale from Saturday.
