Expeditie Robinson 2005 was the sixth Dutch-Belgian version of the Swedish show Expedition Robinson, or Survivor as it is referred to in some countries. The season began airing on September 5, 2005, and concluded on November 28, 2005. The major twist this season was that the tribes were initially divided up by the participants' ages. The Jong (Young) tribe was composed of the contestants age 30 and under and the Oud (Old) tribe was composed of contestants over the age of 40. Unbeknownst to the original tribes, there was a secret third tribe that consisted of two contestants, Esther Jacobs and Marnix Allegaert, who were in their 30s, who lived in an area known as "Secret Island". These two contestants were soon joined by Douwe Popma, who had been voted out immediately after a challenge. In
