<P> This is a challenge where some celebrities have to take part without alerting the other celebrities - if they are successful in their' missions', they are rewarded . </P> <P> A mystery box sees a box delivered to the campsite, each time containing a different gift for the contestants . </P> <P> The show is broadcast Monday to Thursday at 7.30 pm and on Sunday nights at 6: 30 pm (for the weekly eviction show). All shows are presented by Julia Morris & Chris Brown from a nearby studio . The program is live to AEDT States (New South Wales, Victoria, Tasmania and the Australian Capital Territory), in other states the program is delayed to accommodate local time zones . </P> <P> In addition to the television broadcast, for the first season a live feed from the camp site aired for an hour after the AEDT airing of the show on Ten's website and mobile app, titled The Fallout Zone but more commonly referred to as FOZ . The content of feed was available on the website after the fact so viewers in other states could watch the show after their airing of the main show . The feed was hosted by comedian Sam Mac and producer Ciaran "The Butcher" Flannery, also known as "The C - Word". On 8 and 12 March 2015, producer Dominic "The Domin8or" Sullivan filled in during Flannery's absence . The duo interact with viewers through Twitter, using the hashtag #FOZ . Mac and Flannery have no control over the shots used in the stream which has resulted in one episode featuring a 20 - minute shot of a waterfall and, on 16 February 2015, a 15 - minute conversation featuring a sound technician looking for Bob being picked up . On 5 March 2015 the show famously featured audio problems during which Mac and Flannery's voices fluctuated between chipmunk and Darth Vader filters for the first thirty minutes . The show's theme song is Highway to the Fallout Zone sung by Sam Mac . The show did not return for the second season . </P>
