In a brand new episode of the electrifying series, Logie award-winning presenter Grant Denyer agreed to take on Noémie in a thrilling whitewater challenge.

TopKnotz airs Thursdays at 8.30pm on Channel 9 and 9Now.

But first a crash course in kayaking, a decision Grant would come to regret.

"As the only one here who has a genuine fear of drowning, this is like my worst nightmare," Grant confessed.
