"Thank you so very much for supporting MasterChef Australia over the last 11 years. We have loved every single moment," Matt wrote on his Facebook page.
"It is however with a heavy heart that I can confirm that season 11 was our last.
"We were really keen to continue but we were unable to agree to all terms for the new contract.
"We have enjoyed 11 wonderful years on Masterchef Australia with Network Ten, and I want to take this opportunity to thank Ten for this amazing opportunity and for Network Ten’s backing of this very special show.
"We have met some beautiful people, discovered and guided some of the brightest up-and-comers in the Australian food scene, worked with the best chefs in the world in front of the camera, and with the TV industry’s finest professionals behind the scenes. And of course, we three judges have formed a lifelong friendship that will live on far beyond the show."
Matt continued: "I want to take this opportunity to thank you and everyone who has shared our amazing journey with us - especially all those fantastic contestants. I look forward to sharing many more adventures with you in the future.
"And finally I wish the new judges all the best with the show that we love so much.
"I don’t want to take any gloss off tonight’s well deserved winner so I will not be making any further comment."
The news came after New Idea exclusively revealed that Maggie Beer, Curtis Stone, and Poh Ling Yeow are set to take over hosting duties.
Scandal has rocked George after the Fair Work Commission fined him $200,000 for underpaying 515 staff to the tune of $7.83million between 2011 and 2017.
Staff have been repaid but the scandal lingers, with George not only out of his WA tourism gig, but now out of TV as well.
Meanwhile, MasterChef has named Larissa Takchi its 2019 winner, snatching the prize from finalists Simon Toohey and Tessa Boersma.
