Kochie became visibly emotional when he talked about his Sunrise colleagues.

“Well, this is it,” Nat began, “Our last interview.”

“Oh Nat, don’t start me off,” Kochie said, before Nat asked him how he was feeling.

“I’m feeling good. It feels like the right time to move on and bring some flexibility into my life,” he answered.

“(Wife) Libby and I still have things to do on our bucket list that we want to do.”

He then admitted he was “a bit scared” about leaving Sunrise, worried that he might be underestimating the massive adjustment his life was about to undergo.

“I’ll miss it dearly,” he said, becoming emotional.

“I said to Libby, ‘You have to be my rock, because it’s going to be hard.

“I’ve made absolutely the right decision, but I’m scared. It’s a loss, a big part of my life.

“This has been my life, it’s not just my job.”

He added that he loved working with the rest of the Sunrise crew.

“I love working with the people I work with, and not sitting next to you every day will be a massive adjustment,” he said.

“No disrespect to Lib, because I’ll be sitting next to her,” he added jokingly.

“I’ve loved it.”

Kochie has been the longest-serving breakfast TV host in Australian history.

Making the bombshell announcement two weeks ago, he said he was “incredibly proud” of what Sunrise had achieved over the years.

“I’ve been privileged to experience so many adventures, to meet so many incredible people and to cover so many moments of history in the making. It really is the world’s best job,” he said.

“What I’ll miss most is working with the amazing Sunrise team, especially Nat, Beretts and Dave Walters, who have been with me for virtually the entire time on the show.

“I reckon I’ve spent more time with them than my family and it has been an utter joy.

“I’ll miss the Sunrise viewers who have energised me every single day.”
