Minister for Early Childhood and Childcare Kate Ellis has re-confirmed her support for marriage equality.
The South Australian MP said she would back change when same-sex marriage legislation comes to a vote later this year.
Australian Marriage Equality (AME) national convenor Alex Greenwich said he had received a message from Ellis this morning that she does support change.
Ellis also Tweeted her support in November last year.
“Minister Ellis is one of many high profile supporters of reform in the Labor party,” Greenwich said.
Ellis has the backing of conservative union the Shop, Distributive and Allied Employees Association (SDA), whose leader Joe de Bruyn is ardently opposed to a change to the Marriage Act.
“Ms Ellis’ support shows that SDA endorsed MPs can and should back this reform.”
So far AME said it has support to legalise same-sex marriage from 13 of 22 cabinet ministers including Chris Evans, Simon Crean, Stephen Smith, Anthony Albanese, Nicola Roxon, Jenny Macklin, Penny Wong, Peter Garrett, Tanya Plibersek, Bill Shorten, Mark Butler, and Brendan O’Connor.
