It's state versus state, plate against plate, as 12 teams of two from around Australia attempt to out-dine and out-wine each other to see whose kitchen rules.
Taking turns to transform an ordinary home into an "instant restaurant" for one pressure-cooker night, the teams serve up a three-course menu designed to impress not only their fellow contestants but also judges Pete Evans and Manu Feildel.
In this week's episode, the teams travel to New South Wales to see sisters Sammy and Bella Jakubiak devise and prepare their menu.
For the Sydney siblings, cooking is a family affair.
Their grandmother Ursula was a chef in Poland who cooked for many high-profile politicians while she worked as a caterer to the embassies.
"She cooked for a lot of influential people, including Bill Clinton, which was the highlight of her career.
"Cooking is definitely in our blood. It's been passed on from one generation to the next in our family."
Not only have the sisters paired up for the competition but they used to work together in fashion; Sammy (22) as a buyer and Bella (27) in marketing.
But they both quit their jobs to take part in the My Kitchen Rules TV programme and contest.
"We've lived together and worked together for nearly five years and we always cook together," Sammy says.
"We do almost everything together."
Bella adds: "We complement each other. We give each other feedback and support. We're not worried about offending each other. That helps us to grow and get better."
Their favourite dishes are simple, rustic and European, and they think their chicken schnitzel is hard to beat.
"We've grown up eating it," Sammy says.
"It was the first thing we ate after milk. I like to think I make the best."
While cooking might be a breeze for them now, that hasn't always been the case.
They've each burnt down their kitchen on separate occasions in their teens.
"I left hot oil alone while I was on the phone," Sammy remembers.
"The fire brigade came. The entire kitchen was black and the range-hood was melted to smithereens. I spent two weeks scrubbing the walls with sugar soap.
"That was my punishment."
Bella adds: "Mine was a similar situation. It was a pot of oil with chips and the oil caught fire. You have to make mistakes to learn."
In the future, the sisters hope to form their own catering company.
Sammy says: "We would be happy creating a business for ourselves. Cooking brings us joy. We love cooking for large amounts of people; food brings people together."
