We hear from the first Wallabies player to come out as gay, Dan Palmer. Last year he wrote a powerful column in the Sydney Herald saying that his ‘own death felt preferable to anyone finding out that I was gay’. Since this he has had hundreds of people messaging from around the world to say they have encountered similar problems with their sexuality. A few months on he speaks to Caroline about his decision to come out, his battle with his own sexuality and being a gay sportsman. We also speak to the first woman to officiate at the Super Bowl. Sarah Thomas made history as a down judge when the Tampa Bay Bucaneers beat the Kansas City Chiefs and began her officiating career in 1996. Sarah will tell us what it is like to be a history maker, how it feels to be at the pinnacle of her career and how she is blazing a trail for many more women to come.
