On Tuesday, minister for equality Martin Foley announced the legislation, which will amend the Adoption Act 1984 to include same-sex couples.

This will bring Victoria's adoption laws in line with New South Wales, Western Australia, Tasmania, and the Australian Capital Territory.

Foley described the historical discrimination in the Adoption Act as a "black mark" in Victoria's equality record.

"When this adoption bill becomes law, it will provide much-needed certainty for many children and their parents who currently live in a legal haze in terms of their relationships with the people they love," he said.
