"Celebrity MasterChef Australia" is an Australian competitive cooking game show. It is spin-off of MasterChef Australia.
In contrast to its parent show, the celebrity version is based around a heats and semi-finals format similar to MasterChef Goes Large, and is aired only once a week in an hourly format.
Celebrities are split into groups of three as they compete in a heat round featuring two challenges, with one celebrity making their way from each heat into the semi-finals. The heats consist of an Invention Test, in which they prepare a dish of their own concoction, and a Pressure Test, in which they must complete a dish from a professional chef. Due to the difficulty of these dishes contestants are given a single "lifeline" in which the chef is able to aid them for 90 seconds.
The six remaining celebrities will then face further challenges in order to secure their place in the final.
