Heat four called upon the contestants to cook the ultimate cake for the ultimate guest: Prime Minister Julia Gillard. Given two hours and an amazing array of ingredients, the hopefuls produced an incredible display of dessert cooking, with the guest of honour being taken aback by them all. With only four Top 20 aprons up for grabs however, Gracie, Lily, Madi and Jack were judged as the best performers, sending them through to the next stage of the competition. Heat five, the last chance for a Top 20 apron, was an Italian challenge, with the little chefs needing to prepare their finest fare to impress guest judge Alessandro Pavoni. Once again the contestants cooked with incredible maturity, but it was Aya, Hannah and Zac who excelled, winning the three remaining Top 20 aprons.
