The Great Australian Bake Off features ten or twelve passionate home bakers competing in a grueling elimination series, crafting a mouth-watering selection of cakes, pies, tarts, pastries, bread, biscuits, and desserts, all in the hope of being crowned Australia's Best Home Baker. 

In each episode, contestants are challenged with a signature bake, a technical bake, and a showstopper, with judges critiquing their creations and ultimately selecting a "Star Baker" and eliminating one contestant each week. The show tests their baking skills, creativity, and prowess under pressure.
