At the table of Peruvian contestants, Andy, 31, and Ruby, 39, siblings from Perth Blake, 32, and Amanda, also 29, decided to joke about this season's villains.
"I think the whole immature palette thing only correlates to these two!" Blake said, with Amanda adding, "Their brains haven't finished developing yet."
Although the comments were made in jest, the brothers were deadpan and looked unimpressed.
While older brother Josh kept his cool at the table, in a piece-to-camera interview the devout Christian exploded into a tirade, exclaiming "shut the f**k up" before hurling a number of inaudible swear words.
This isn't the only drama to follow Josh and Austin.
The two brothers spilt the beans the New Idea about a secret My Kitchen Rules feud bubbling away behind the scenes.
Josh and Austin have made shocking allegations to New Idea, labelling “Friendly Pirate” Ash “fake” and a “full of s--t”. “Stacey and Ash were so full of s--t the entire time,” Josh, 25, spills. “He really got to Austin a lot. It got very, very serious between Austin and Ash, and Ash kept picking on him.”
Austin, 22, is outraged Ash has been portrayed positively on the show, claiming things were very different when the cameras stopped rolling. "He did horrible things," Austin states.
"He threatened me. I asked some challenging questions and it's up to them how they take it. Some of them broke and it was a thing because it means they failed, and some freaked out and Ash got really threatened. He was just a peacock trying to spread his wings. He threatened me so many times and it makes me think he started that fight [where he lost his eye].”
