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.

Sportshour's Katie Smith tells us the story of two Ironman trailblazers.

We are live at the Australian Open to see which female will win the Grand Slam.
