Grab your backpack, throw on your runners, and leave your passport behind. The Amazing Race Australia is about to set off across Australia in the ultimate race of a lifetime.

While international travel may not be on the itinerary, this island nation filled with immense beauty and extremes, has many great landscapes to challenge even the most avid racer: from beaches to deserts, rainforests to mountain ranges, tropical hot climates to freezing snow.

So, who needs jetlag, lost luggage and flight cancellations when you can experience the trip of a lifetime, in your own backyard?

This season 14 competitive teams will race, criss-crossing the nation and taking part in the heart-stopping and stomach-churning challenges, all with their eyes on the $250,000 prize.

And with the new season comes the addition of new race rules – some considered an advantage, and some, not so much.

Rule master and cheeky host with the most, Beau Ryan returns for season two, dolling out rewards and punishment, and ultimately keeping teams in check.

Who will triumph? Who will fall? And who will ultimately win The Amazing Race Australia?
