From gladiatorial combat to a different kind of battle: our latest crop of castaways will once again be at each other's throats when Australian Survivor: Titans v Rebelslands back on the beaches of Samoa.

Hosted by Jonathan LaPaglia, the Titans are both physically intimidating and utterly ruthless, but they'll need to be at their absolute best to take on the Rebels – a group of individuals who live life by a different set of rules.

Think you know the game of Survivor? Think again.

Australian Survivor has always been an individual game, but this season, it's all about to change.

For the first time ever on Australian Survivor, castaways will be playing with a member of their own family.

Siblings, couples, in-laws, parents and children will all go head-to-head in the highly anticipated new season of Australian Survivor: Blood V Water.

Battling it out for the title of Sole Survivor will be, Australian Survivor Season 2 contenders Mark Wales and Sam Gash, NRL Legend Michael Crocker and his sister in-law Chrissy Zaremba, alongside the Queen of Survivor US Sandra Diaz and her daughter Nina Twine, plus more to be announced soon.

Will blood prove to be thicker than water? Or will the deepest bonds be broken?

Think you know the game of Survivor? Think again.

For the first time in Australian Survivor history, 24 of the strongest and most strategic minds the competition has ever seen, will go head-to-head in the Australian Outback, where they'll settle the age old question: Brains or Brawn?

Over 48 days in the vast, arid outback of Cloncurry in North West Queensland, 12 of the most intelligent individuals will take on 12 of the most physically elite as they attempt to Outwit, Outplay, and Outlast the competition to take home the title of Sole Survivor and a life-changing $500,000.

The Brains Tribe aren't just about smarts. They're creative, mentally strong, charismatic, and strategic. Think political operatives, authors and doctors who have used their mindpower to get them to the top of their fields.

Forget bulging muscles and protein shakes, The Brawn Tribe not only have the physical strength, they're hard workers with a drive and competitive edge that's taken them to the top. With MMA fighters, professional surfers and models, they're used to putting their bodies on the line and pushing themselves to the limit.

Both Tribes will take part in Reward Challenges, where they will compete for luxuries including food and camping essentials. In Immunity Challenges, they will play for Immunity, saving them from being voted out of the game at the next Tribal Council. At each Tribal Council, a Tribe must vote out one of their own to keep themselves in the running for the title of Sole Survivor.
