Network 10 has pulled the plug on Matt Preston, Gary Mehigan and George Calombaris, confirming the trio will not return to MasterChef next year.
Chief executive officer Paul Anderson said: "Despite months of negotiation, 10 has not been able to reach a commercial agreement that was satisfactory to Matt, Gary and George."
"We would like to thank Gary, George and Matt for their contribution over the past 11 years," he said.
"MasterChef Australia has always been about ordinary Australians doing extraordinary things for the love of food and we believe it is very important to continue that ethos.
