It is unknown what form of cancer Granger had.
The initial statement from the celebrity chef’s family did not disclose a cause of death.
It simply stated that the father-of-three died “peacefully” in hospital in London, surrounded by his wife Natalie Elliott and daughters Edie, Inès and Bunny.
“He will be remembered as the ‘King of Breakfast’, for making unpretentious food into something special filled with sunshine and for spurring the growth of Australian informal and communal eating around the world,” the Instagram post read.
“He will be deeply missed by all, with his loss most profoundly felt by his adored family, who are grateful for all the love and support that has been given.”
Granger’s wildly successful restaurant bills, which he opened in 1993 in Sydney’s Darlinghurst, brought him to fame as a chef.
In 2008, he launched the business globally, opening his first international bills in Japan and, later, in the UK and Korea.
He also wrote 12 cookbooks, which sold more than one million copies.
His most recent, Australian Food, was released in 2020.
The self-taught chef, who was born in Melbourne, dropped out of art school in 1993.
In October that year, he opened his first bills, in Darlinghurst.
Granger was also the star of several culinary TV series, including Bill’s Tasty Weekends and two seasons of Bill’s Food, both of which aired in the UK.
In January 2023, he was honoured with the Medal of the Order of Australia for service to the tourism and hospitality sector.
