The Big Adventure is an Australian reality television series that premiered on the Seven Network on 19 October 2014,[1] and is hosted by Jason Dundas.

True Colours: The players were asked to traverse a course offshore and match the flags, as seen from a far distance, on the structure.

As the winning team from the previous challenge, each player from the Orange team, except for Paula who injured her ankle shortly after the first challenge the previous day, was to run across a bridge, grab a telescope, view the six flags from the far distance, return to the platform, jump into the water, find the six flags then try to memorise the pattern that they had seen through the telescope.

Whichever player was first to win the challenge (that is, correctly reprising the pattern that they saw through the telescope) would then have the right to dig through the treasured grid at the end of the episode.

Next, the blindfolded player had to navigate through a higher part of the course, retrieve a second wooden handle, and then play a maze where they had to roll the balls through to the holes at certain dead ends.
