In 2012, Croome became the fifth National Director of Australian Marriage Equality. On 8 May 2013 Croome debated Patrick Langrell on Same Sex Marriage at the University of New South Wales. In September 2013 Rodney Croome wrote to the group Community Action Against Homophobia CAAH expressing his concerns in regards to the radical campaigning methods they use in same-sex marriage campaigns saying, "It is a double standard to demand respect for same-sex relationships without showing the same respect in return". Croome supports Australia's trans and intersex communities in their quest for marriage equality saying, "the marriage equality campaign must be inclusive of all loving committed couples regardless of sex, sexual orientation, gender identity or intersex status".
