Kerri-Anne Kennerley's Husband John Kennerley Has Died

Kerri-Anne Kennerley's husband John Kennerley has sadly passed away after "tremendous challenges".

The Studio 10 host took to Instagram to confirm he passed away on Wednesday night, with his family by his side.

"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.

"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.

"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.

"John, you were the love of my life."

He was 78 years old.

John experienced a life-changing injury in March 2016 that left him partially paralysed.

While attending a party at a Coffs Harbour golf course, John slipped on the outdoor deck, breaking his C2 and C3 vertebrae.

Kerri-Anne and John -- married since 1984 -- transformed their home to become wheelchair accessible.

John's last Christmas with his family by his side. "A happy healthy family, the only present I need this Christmas," Kerri-Anne said.

Kerri-Anne's Studio 10 co-hosts were in tears on Thursday morning as they announced the news live on air.

"John is someone I have known with Kerri-Anne for more than two decades and he is just an extraordinary man," Angela Bishop said, wiping away tears.

"He had a beautiful, warm heart, and he and my late husband became friends because they were always the plus one together at functions. He was a beautiful, beautiful man, and this is just devastating news.

He really was just the love of Kerri-Anne's life."

Richard Reid described them as a "couple of kids in love" who suffered a "devastating blow".

"She would beam at him and he would beam at her and it was just so fabulous, so my heart is just so heavy. You are a legend, a legend and a beautiful woman and wife and a fabulous individual."

Kerri-Anne's Network 10 colleagues Sandra Sully and Lisa Wilkinson expressed their devastation at the news.

"I am devastated for her. John has been the love of her life and been with her privately and professionally every step of the way," Sully said.

"I can't imagine her loss and grief right now. I am so very sad."

Wilkinson said her thoughts were with Kerri-Anne and the family now and during the "difficult days, weeks and months ahead."

"Their love for each other was absolute," Wilkinson said.

"Never moreso than in the years since John's tragic accident. Vale."

Prime Minister Scott Morrison said John and Kerri-Anne's love story is one showing "how lucky we are to have people we love in our lives".

"I'm sure Kerri-Anne will be deeply comforted by that relationship over such a long period of time and I'm sure she will get enormous waves of comfort from the Australian people," he said at a press conference announcing Ita Buttrose as the new ABC chair.

"They shared their story openly with the Australian public and they let people into a very private part of their lives and I think the strength, determination and compassion and care that was shown in that relationship was an inspiration to all Australians.

"We love you very much, Kerry Anne and we hope that these days and weeks ahead are not too arduous, but we know they will be, and you have the love and care of the nation with you."

Buttrose also offered kind words and sympathies.

"I'm really sorry to hear it because I like him very much," she said.

"They were a great couple and she adored him."

Network 10's CEO Paul Anderson offered his deepest sympathies to Kerri-Anne and Simon on the passing of their "beloved husband and father".

"John faced some enormous challenges over the last few years and during this time, Kerri-Anne, in her usual grace and stamina, has shown enormous strength, compassion, love and commitment," Anderson said.

"Our thoughts are with Kerri-Anne, Simon and their family during this difficult time."
