Beauty and the Geek Australia

In tonight's season finale, the Beauties and Geeks test their relationships mentally, physically and emotionally. In three extreme challenges, the final four couples must rack up as many points as they can by swimming above a frenzy of feeding sharks, locking lips with their partners and competing blindfolded in a jungle obstacle course. Then, the three remaining couples will battle it out in a disco dance-off. Judged by a live audience, the two teams with the most votes will go on to the very last challenge of the series - the final elimination quiz.
