"In a nation obsessed with food, we are thrilled to welcome Jock, Melissa and Andy as judges to MasterChef Australia", Ten chief content officer Beverly McGarvey says.
The replacements for Gary Mehigan, George Calombaris and Matt Preston have been revealed, with next year's season of Masterchef on Ten to be fronted by Jock Zonfrillo, Melissa Leong and Andy Allen.
In the time since, the 31-year-old has continued to ride the wave of success, launching his own restaurant Three Blue Ducks in Sydney along with creating food-based travel vlogs.
The trio of Mehigan, Calombaris and Preston was ditched earlier this year, when contract negotiations with Ten broke down.
"But now to see them back, putting their knowledge against each other in the Masterchef kitchen, sets the stage for the most exciting season yet".
There was speculation that household names including Maggie Beer, Curtis Stone or Poh Ling Yeow might be cast as the new judges, but instead Channel 10 has chosen a trio of relative unknowns. "I can't wait to get in that kitchen".
Melissa Leong is a food writer who has appeared on SBS's reality cooking show The Chefs' Line. The shake-up also came at a time that Calombaris was facing heat in the media and hospitality industries over underpaying workers.
Who are the new MasterChef judges?
Allen was the victor of the fourth season - the youngest contestant to win. "I am really looking forward to getting stuck in".
Leong is a food and travel writer and presenter while season four victor Allen is now co-owner of the Three Blue Ducks and is head chef of their Rosebery restaurant, which went on to be awarded a Chef's Hat, making him the first MasterChef contestant to achieve the feat.
"It would probably have felt worse if I was by myself, but the fact I was with one of the publicists with Ten who had no idea and who was just aghast by the situation, especially about to go and do a national radio show, it was a bit of a shock", he later said on ABC radio.
"Jock's culinary resume across Australia and the United Kingdom puts him in the very elite of contemporary chefs", Endemol Shine Australia CEO Carl Fennessy said. "To be asked to be a judge - and to come full circle back to Masterchef Australia - is really flattering and really special", he said.
The first female judge on MasterChef Australia, Leong, is a first-generation Singaporean Australian.
"I'm stoked because it means that I've done the hard work to be here".
