Grant Denyer has announced his latest career move.
The longtime television host will be fronting a new adventure series called TopKnotz on Channel 9.
Gold medallist Noemie Fox is also taking part in the series, which is based on the car-based TV series Top Gear.
Grant, 47, said that fans can expect a thrilling ride ‘on the water, over and through the water for a whole world of aquatic adventure’.
The series has been shot by award-winning marine cinematographers and a fleet of drones for a slick and exhilarating look.
Grant has been spotted filming the series at Penrith Whitewater Stadium – and he was not sitting by the sidelines, taking active part in the show’s high octane challenges.

Last year, the Channel 10 star revealed he’s ready for a major career change.
The Deal or No Deal host confirmed at the time that he had pitched a new show to the Nine network.
However, the Gold Logie winner said he could be waiting years for an answer from the station’s bosses before he gets the go-ahead for the project.
The popular Dancing with the Stars winner made the admission during an interview with TV Tonight.
In a surprising revelation, Grant also said that he had a series of programs with ‘other networks’ and producers besides Nine.
‘I’m keen to get some of my own projects up,’ he said.
‘I’ve still got something sitting with Channel Nine at the moment, so hopefully something happens there that’s in partnership with a production company and just building some ideas.’
Grant said he has messaged Nine’s Head Of Content, Production & Development Adrian Swift for updates on his project.

‘I keep texting him [Swift] every now and then he goes, ‘”Yeah, it’s still on the boil. We still love it,”‘ but getting them to commit it’s a slow game, this kind of s***.’
‘I’ve been told sometimes a network can have an idea in the drawer for five years before they bring it out. So I think patience is the game.’
Grant also revealed he has a few more ‘ideas up his sleeve’ and has also approached different networks.
It comes after Grant opened up about his health struggles, claiming that he was pushing himself so much to the point where a doctor told him he ‘was going to die’.
Appearing on the Mental As Anyone podcast, Grant said: ‘I was skinny as a rake and unhealthy as hell and the doctor said my organs were running at about seven per cent.’
‘He goes, ‘If you don’t do something about this in the next four weeks, you’re going to die’.’
‘It took two lessons for me to realise that I had to change my mindset and how I was approaching life and what I prioritised as important until I learned the lesson and I feel like if I hadn’t learned it the second time, it would have been fatal the third.’
The previous two lessons for the Gold Logie winner were breaking his back in a car accident, and his chronic fatigue diagnosis.

‘I broke my back, which I firmly now believe was not as a result of jumping seven cars in a monster truck but as a result of ignoring all my bodily signs, ignoring all the signals my body was trying to give me to slow the hell down,’ Grant continued.
‘You can’t sustain this pace and this grind and this aggressive chase for the next rung of the ladder, because you will die.
‘As my body was deteriorating and my mental health was deteriorating, the monster truck crash came along to sit me on my a**,’ he added.
Grant is currently hosting Deal or No Deal for Channel 10.
