The fourth season of The Great Australian Bake Off premiered on 18 January 2018, and saw 12 home bakers take part in a bake-off to test their baking skills as they battled to be crowned The Great Australian Bake Off's best amateur baker. Unlike the third season, season 4 moved from LifeStyle Food to the main LifeStyle channel. The season consisted of 10 episodes. Each episode saw bakers put through three challenges, with each episode having its own theme or discipline. The season aired from 18 January 2018 until 22 March 2018, and saw Claudia Anton win. The season was hosted by Claire Hooper and Mel Buttle, and was judged by Maggie Beer and Matt Moran.
