 Hunter and his partner of 20 years, Leith Semmens chose to travel to Spain to marry as Australian law did not recognise same-sex marriage at the time.In June 2008 Hunter introduced a number of amendments to the Statutes Amendment (Surrogacy) Bill, including removing the term "marriage-like relationship" in order to remove discrimination against same-sex couples.The amendment would effectively give same-sex couples the legal right to access gestational surrogacy.
