There seems to be a lot of confusion about this show. The US Impractical Jokers {The Tenderloins) along with the production company sell the rights to their show format all around the world. There are many different regional versions of the show and this just happens to be the Australian version.
People complaining of copyright are pretty dense. The Tenderloins make money every time the format is sold, this version included.
All in all, the show is a near copy of The US Impractical Jokers show, but skewed a bit younger. It's fun and funny, but pales in comparison to the US version.
Overall, good for a laugh, even more so than these ill informed reviews.
