I'm A Celebrity duo Swash and Flack will be the team captains, while the Aussie TV presenter and NBC's Love In The Wild star McMullen will have the hosting role.
Flack and Swash will be challenged to look after teams in a number of wacky challenges that have a 60-second time limit. Some of the tasks include stacking ten nuts using only chopsticks, throwing as many cards as possible in a halved watermelon and moving ping pong balls between cups of water by blowing.
McMullen said: "I've hosted many shows in several different countries around the world and I can honestly say that I've never had so much fun in my TV life than I had during the filming of Minute To Win It UK.
"Having Flacky and The Swashing Machine as team captains added a fantastic dynamic to the show that I'm sure will be plain for all to see on camera. I dare you to watch this show and not like it."
Shine TV's executive producer Lisa Perrin, said: "Darren is a hugely popular host of the show in Australia. Already familiar with the format and the games, he was the natural choice for the UK version and is well placed to keep Joe and Caroline in line!"
Minute To Win It will air on ITV2 in the autumn.
