John, 78, died in late February of pneumonia after he was left paralysed from the neck down after a serious fall in 2016. The couple had been blissfully married for 35 years.
On Thursday, Feb 28, Kerri-Anne Kennerley, who famously accepted her Logie Hall of Fame award with her husband, took to Instagram to share the tragic news.
"It's with a heavy heart and awful sadness that I let you know that my beautiful husband John passed away last night," she wrote alongside a wedding photo.
"As you all know, John has faced some tremendous challenges over the past few years and with each he has been extraordinarily brave and determined to overcome those hurdles and live a normal life."
She then addressed all those who helped him during his trialling time.
"I want to thank everyone at St Vincent's Hospital for the beautiful care they have provided to John in his last days."
"John passed away peacefully with his son Simon and me by his side."
Kerri-Anne ended her tribute, saying, "John, you were the love of my life. Xxx"
