Master Chef Australia is a Logie Award-winning Australian competitive cooking game show based on the original British Master Chef.
It is produced by Shine Australia and screens on Network Ten.

The second series aired through the week at 7.30 pm, half an hour later than the original timeslot of the first series.
The winner of the 2010 series of Master Chef was Adam Liaw, who won by a seven-point margin over his opponent Callum Hann.
The eighth series premiered on , and was won by Elena Duggan who defeated Matt Sinclair in the series finale.
The series has also spawned four spin-off series: Celebrity Master Chef Australia, which featured celebrity contestants, Master Chef Australia has a different format to that of the original British Master Chef and Master Chef Goes Large formats.
Initial rounds consist of a large number of hopeful contestants from across Australia individually "auditioning" by presenting a food dish before the three judges in order to gain one of 50 semi-final places.
Entrants must be over 18 years old whose main source of income cannot come from preparing and cooking fresh food in a professional environment.
The semi-finalists then compete in several challenges which test their food knowledge and preparation skills.
In Season 1, the top 50 competed until 20 were left, with the final 20 progressing to the main stage of the show. The contestants will then be whittled down through a number of individual and team-based cooking challenges and weekly elimination rounds until a winning Master Chef is crowned.
