The Scottish-born chef of the Orana restaurant in South Australia joined the Channel 10 program in 2019 and starred alongside Melissa Leong and Andy Allen in the series.
Zonfrillo is survived by his third wife, Lauren Fried, and his four children, Alfie, Isla, Ava and Sophie.
The chef's family released a statement confirming his passing, saying: “With completely shattered hearts and without knowing how we can possibly move through life without him, we are devastated to share that Jock passed away yesterday.
“So many words can describe him, so many stories can be told, but at this time we’re too overwhelmed to put them into words. For those who crossed his path, became his mate, or were lucky enough to be his family, keep this proud Scot in your hearts when you have your next whisky.
“We implore you to please let us grieve privately as we find a way to navigate through this and find space on the other side to celebrate our irreplaceable husband, father, brother, son and friend.”
Channel 10 confirmed the sad news in their own statement saying: “Network 10 and Endemol Shine Australia are deeply shocked and saddened at the sudden loss of Jock Zonfrillo, a beloved member of the MasterChef Australia family. Jock passed away in Melbourne yesterday.
“Jock was known to Australians as a chef, best-selling author, philanthropist”.
“Determined and talented and with plenty of grit, Jock was born in Glasgow to an Italian father and a Scottish mother, which meant his formative years were heavily influenced by two strong cultures and it was his obsession with food and desire for a new pushbike that at just 12 years old fuelled Jock to knock on kitchen doors looking for a job.
“Jock’s love and passion for food saw him become one of the youngest culinary students to do an apprenticeship at The Turnberry Hotel at just 15 years of age. From that point onwards there was no holding him back and by 17 he was working alongside Marco Pierre White at his eponymous Restaurant Marco Pierre White.
“Throughout his career he worked with world famous chefs and in restaurants all over the world. His talent saw him shine in the world’s most formidable kitchens and he opened Bistro Blackwood and Restaurant Orana in Adelaide after moving to Australia.
“Jock’s Restaurant Orana was recognised with the coveted distinction of three hats in both 2019 and 2020 and he also received global accolades, accepting the prestigious Basque Culinary World Prize in 2018.
“In 2019, Jock was named as a judge on MasterChef Australia in which he took great pride in challenging and coaching the contestants and of course inspiring a nation of home cooks.
“Jock’s charisma, wicked sense of humour, generosity, passion and love for food and his family cannot be measured. He will be greatly missed.”
Channel 10 confirmed that the new series of MasterChef Australia, which was due to air tonight, will be postponed.
The renowned chef established himself in Australia as the head chef at Restaurant 41 in Sydney in 2000, before going on to open Restaurant Orana in 2013.
He initially worked under renowned Michelin-starred chef Marco Pierre White.
