His replacement will be Tim Shaw, dubbed Australia's most successful television salesman, who will take over the microphone in early January.

Shaw may be a veteran journalist and radio host but he rose to prominence selling Demtel steak knives on Australian television in the 1990s, becoming synonymous with the catchphrase "but wait, there's more".

The presenter and producer will replace veteran broadcaster Parton, whose final breakfast show will be on December 18.

The father of three has spent the last three years living in Thailand, where he was a senior journalist with the Seven Network's South East Asia bureau.

2CC program manager Peter Davidson said it would be a "smooth transition" between radio hosts.

"Tim's got a very similar personality and style on air [to Mark]. He's going to embrace Canberra," Mr Davidson said.

"It'll be a climate change [moving from Thailand] but a good change. It'll be a big year, we have two elections next year locally and federally and he's very excited and can't wait to get here and talk to the listeners and have a crack at shaking things up in Canberra radio next year."

It won't be the first time Shaw has been broadcast on the Canberra radio station.

His radio show Legal Matters was syndicated on talkback stations across Australia, including 2CC.

In a statement, Shaw said he was delighted to be joining the 2CC team.

"After 20 years in talk radio, the 2CC Breakfast program affords me an exciting opportunity to live in our nation's capital and share the news and views that affect the local Canberra community," he said.

Shaw is no stranger to Canberra either.

He was once mobbed by shrieking fans outside Parliament House, he told James Cockington of the Sydney Morning Herald in 1994.

"Three or four hundred schoolchildren were lined up for the Parliament House tour. Children watch television. I suddenly heard the shriek, 'Oh, look, it's the Demtel Man'. They all broke ranks, ran up to me and started reciting 'but wait, there's more'. They even knew the Demtel phone number," he said.

Former host Mark Parton announced he was leaving the station last month after seven years with 2CC and 16 years on Canberra radio.

Parton will turn his attention to growing his own Canberra-based marketing and social media company, Parton Me, and hasn't ruled out standing for the Legislative Assembly in 2020.

2CC Breakfast with Tim Shaw at the helm kicks off on January 11.

It is unclear whether 2CC listeners will receive free steak knives.
