Hugh Jackman and Olivia Newton-John are among the famous Australians who on Monday endorsed gay marriage, The Sydney Morning Herald reported.

“With respect to marriage equality, I believe that no-one has the right to judge and deny couples who love each other the ability to make a marriage commitment,” Newton-John said in a statement.

“Love is love as much to same-sex couples as to other Australians,” she added.

Also signing on to the endorsement are Wallaby's captain David Pocock, film critics David Stratton and Margaret Pomeranz and costume designer Lizzy Gardiner.

The effort to legalize marriage for gay and lesbian couples in Australia got a large boost late last year when Australia's dominant party, the Australian Labor Party (ALP), agreed to alter its long-standing party platform opposing such unions. At its annual conference in Sydney, party leaders also adopted Prime Minister Julia Gillard's motion to allow lawmakers to make a “conscience vote” on bills related to gay marriage, which allows lawmakers to vote as they please rather than the party line, a move widely seen as diminishing the effect of the ALP's endorsement.
