Sporting bodies across Australia back gay marriage, with cricket the latest to support same-sex unions as a postal vote on the issue began.
Fifteen organizations to have signed an open letter urging marriage equality include Football Federation Australia, Basketball Australia and the National Rugby League. Those yet to show their hand include Tennis Australia and the Australian Rugby Union.
Cricket Australia chief executive James Sutherland said: "Cricket must be a welcoming environment for [everyone] regardless of gender, cultural heritage and - importantly in the current environment - sexuality."
The vote closes on November 7, with a result on November 15.
Despite solid support for marriage equality and homosexual rights, few Australian athletes have come out as gay. Those who have include tennis star Casey Dellacqua, rugby league's Ian Roberts and five-time Olympic gold medal swimmer Ian Thorpe.
