The best of the best return for the Semi-Finals! Judges Shane Jacobson, Lucy Durack, Nicole Scherzinger and Manu Feildel have selected 30 acts to come back and battle for a place in the Grand Final.

It’s Top 21 week and the incredible performances just keep coming. In front of a live audience, the pressure is truly on. Who will transform into a superstar, and who will let the nerves get to them?

With a special appearance from Tate McRae, it’s the last of the Top 21 performances. Only 12 Idol hopefuls will continue to the next round and keep their dream alive, to be the next Australian Idol.
