Comedian, actress and marriage equality advocate Magda Szubanski has taken aim at prime minister Malcolm Turnbull for his "gloating" speech on same-sex marriage, saying the prime minister should check his demeanour.



Szubanski, who is best known for creating and starring as the character of Sharon in Kath & Kim, was one of the most prominent faces of the "yes" campaign in the national survey on same-sex marriage.

She told reporters on Tuesday that she thought the prime minister's speech, which was glowing in its assessment of the survey, was tone deaf, given the deeply negative experience many LGBTI people had during the same-sex marriage vote.



In his speech, delivered around lunchtime on Monday, Turnbull noted that he was "the first prime minister of Australia to be unequivocally and consistently in support of legalising same-sex marriage".

"It will be forever to the credit of the Coalition that this momentous social change occurred with the overwhelming mandate of the Australian people, under a Coalition government," he said.

Turnbull also lauded the postal survey on same-sex marriage, which was opposed by much of the LGBTI community, as "one of the most remarkable political events of my lifetime".
