I think the hidden secret could a wilderness tribe living off the land in this wild Tasmanian Jungle. Maybe, if you wander far enough into the forest, you will start to find clues, that will lead you to the to the whereabouts of this obscure tribe. As you start getting closer, the tribe will send the kids to come and find you and take you to their home. The woman of the camp will cook you dinner and give you beds for the night. In the morning, they will point you in the right direction, give you some food and send you home.
