Changes
In contrast to prior series, Junior MasterChef Australia is produced by Shine Australia. The series premiered on Sunday, 12 September 2010. It also added Anna Gare as fourth judge during individual challenges.

The series began with the Top 50 selected from the 5,500 applicants who auditioned for the show. The Top 50 featured five heats, with ten from the Top 50 who were best at the heat's team participating in each heat. Afterwards, the judges selected four to move forward to the Top 20. Furthermore, the Top 20 competed in two challenges to pick the Top 12. Contrast to other versions, contestants are not eliminated every week; rather, four are eliminated at every stage of the competition. Every eliminated contestant received a range of prizes, including those in the Top 50.

Contestants
The top 12 contestants were chosen throughout the first week of challenges amongst the Top 50 and the Top 20. The full group of 12 were all revealed on Sunday, 26 September 2010:

Notes:

– Isabella and Sofia Bliss are fraternal twins. – Jack Lark was 12 years old during his audition for the show, the maximum age for the cooks who auditioned. Afterwards, he turned 13 during their first week in the MasterChef Kitchen.
