Castaway: Fundraiser for Survivor UK

 was the eighteenth season of Castaway and was produced on TBC, 2022.

The season borrowed elements from the CBS reality television competition Survivor. Hosted by Robert, the game consisted of x competitors.

A spin-off of Castaway the season was created to raise funds for the Live Reality Game Survivor UK. The two tribes, Joshua and Robert, were named after the hosts of Survivor UK.

Development and Casting
On conclusion of the previous season, Rob announced the end of Castaway to focus on other projects. In April 2022 Robert and host of Amnesty Joshua (who previously competed in & ) began work on a Live Reality Game in the United Kingdom.

The decision was made to host games based on Robert and Joshua's most well-known series and raise funds from those competing. In lieu of a cash prize, the winners of both games will be gifted an exclusive set Survivor UK buffs each. Casting was open to all, with no restrictions imposed on alumni to Castaway.

Unlike previous seasons of Castaway where the season employs twists, tribes and the general aesthetic, Fundraiser for Survivor UK features a wholly unique aesthetic.
