Karl Stefanovic announces new career move outside of Channel Nine: 'I'm going to unleash the beast'

Karl Stefanovic has launched a new career path outside Channel Nine.

The Today show presenter, 51, will be hosting his own YouTube podcast.

Karl, who has appeared on the breakfast show for 20 years, announced the news on Instagram on Thursday, sharing a clip of himself hard at work in a recording studio.

'So, I have some pretty exciting news. I have this curious beast that lives inside my head, and I'm about to unleash that beast,' he said.

He reassured fans that as the project is entirely his own, he'd have full freedom over how the show is run.

'I am free and independent to talk to the people I am curious about. People who have done amazing things, people who have stories to tell,' he added.

'It's interesting, unscripted, unfiltered and uncensored. I am going to unleash the beast. Are you ready to walk on the wild side? The Karl Stefanovic Show is coming soon, it's going to be fun.'

He revealed some of the things he hoped to achieve with this podcast and the very surprising person he would be having as the show's first guest.

'A few decades on the telly has given me a very good bulls**t metre - and an an eye for a bloody great story,' he explained.

'This show will be the people I know you want to hear from too - across politics, sport, business and culture. I'll go there. Why not? No spin. Lots of fun.

'We start this Sunday with a live show at 2pm with Pauline Hanson - live on YouTube.'

Karl has been the co-host of Channel Nine's breakfast show Today since 2005.
