MasterChef Australia All-Stars is an Australian cooking reality show that aired on Network Ten from 26 July 2012. It featured a number of returning contestants from the first three seasons of MasterChef Australia (including season 1 and season 3 winners Julie Goodwin and Kate Bracks), revisiting past challenges in order to raise money for charity.

The series aired for three weeks, mostly during the 2012 Summer Olympics. It was also the last iteration of the show to be shot in the MasterChef kitchen in Alexandria, Sydney, home of the series for all past seasons.David Knox, "MasterChef exits the kitchen in hunt for a new home", TV Tonight, 14 August 2012

Contestants The following contestants returned from seasons 2009 (Blue Team), 2010 (Red Team) and 2011 (Yellow Team). Notable absentees were Season 2010 winner Adam Liaw (due to shooting his new TV series) and Season 2011 runner-up Michael Weldon. The initial stages of the competition focused on the Teams raising money, but from episode 7, contestants competed separately and were eliminated in order to crown the 'best of the best' All-Star.
