"I will miss him beyond words and with the support of our gorgeous children, Oscar and Emily, and their partners, we will continue to live in the manner he wanted.
"When I asked Jono recently how he wanted to be remembered, he said, 'For doing a good deed every day."' Such was the generosity and caring nature of the love of my life."
Jonathan's devastated son Oscar also paid tribute to his late father in a touching Instagram post.
Sharing a snap of himself wrapping his arm round his dad, he simply wrote: "Love you dad. Rest in peace @jonocoleman."
Tributes from various celebrities have poured in following the news of Jonathan's passing.
His former Studio 10 co-star Jessica Rowe took to social media and penned: "'My heart breaks today remembering the joyful Jono Coleman,' she wrote on Instagram.
"He spread love & laughter wherever he went. The most I’ve ever laughed was when he covered himself in sausages to lead a dachshund race on Melbourne Cup day. I’m sending all my love to Margot & Oscar & Emily. Vale Jono."
Coleman had an hugely successful career in both Australia and the UK on TV and radio.
He started off his career as a presenter on the afternoon children's program Simon Townsend's Wonder World in 1979.
Coleman then had stints at Triple J and Triple M, before heading over to the UK to continue building his radio career.
Most recently, he's been a firm fixture on Australia's Channel 10's morning show, Studio 10.
