The law opening civil unions to same-sex couples was legalized in 2008 before being suspended. In handing them available, this provides recognition of these relationships before getting the equal marriage.
MPs overwhelmingly voted in favor of this law with 64 votes in favor and 22 against.
"I welcome the Queensland government’s Civil Partnership law because it will provide same-sex couples with greater legal certainty," said Rodney Croome of Australian Marriage Equality.
"But civil partnerships are not a substitute for equality in marriage for same-sex couples."
Before a possible law on equal marriage, which won't take place before 2017, a plebiscite is to be held soon.
