George's mum arrives in the Masterchef Kitchen to put the contestants through their paces.

Guest chef, Vincent Gadan, is thrown a curve ball in the Immunity Challenge. A sweet treat whiz, will Vincent cope cooking a roast pork? Or will our MasterChef contestant win that illusive pin?

The contestants head to the newly-developed Westfield shopping centre food court in Sydney city to compete in another epic team challenge.

The axe falls on another contestant but not before they must serve up a '60s classic.

In the elimination challenge, the contestants are dressed in blindfolds for a taste test and then must cook only with the ingredients they guessed correctly.

The remaining 12 contestants have made it past the half way point, and what better way to celebrate than at Matt Moran's family farm in rural NSW.
