Australia's first "say no to same-sex marriage" advertisement aired this week and it featured three mothers talking about the adverse effects same-sex marriage could have on their children.
The ad featured Heidi McIvor, a church pastor, Dr Pansy Lai, a GP, and Cella White, a critic of the Safe Schools programme.

"Kids in Year 7 are being asked to role-play being in a same-sex relationship," McIvor said in the ad.
She is a mother of two and, according to her LinkedIn profile, a former media adviser to Family First senator Steve Fielding, the senator who, in 2009, compared same-sex marriage to incest.
