Despite viewers labelling the pair as 'villains' the brothers seem to be taking the criticism in their stride and doing nothing to quell it.
Posting on their MKR official Instagram story, the brothers Instagrammed a shot of themselves with the words:
"Everyone at the table:...
"Josh and Austin: Can I just say Romel looks like Randal from monsters inc."
The Instagram story is following on from a somewhat mean-spirited post made last week, that compared fellow contestant Romel to a cartoon monster.
MKR's Christian brothers have been known for stirring the pot, but last night the contestants seemed fed up with Josh and Austin's antics, with one contestant suggesting that the two brothers aren't mature enough for the competition.
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."
