I haven't seen it (don't want to) but I had to google the host & there was an article about how the ratings tanked & it was moved to another channel. Here's a portion of that article:

"Despite the show being a ratings flop in Australia, Dawson remains hopeful the show will return for a second season.

Last week, Channel 10 bumped the series to its least-viewed multichannel 10 Shake as the dud reality series continues its ratings decline."
