MUMBAI: US television network CBS has unveiled the identities of the 16 castaways participating in Survivor: Thailand. The series premiere's 19 September.

The castaways include 60-year-old land broker Jill Billingsley, real estate agent Erin Colins and professional firefighter Stephanie Dill.

The show, hosted by Jeff Probst, will strand 16 Americans on Koh Tarutao, a remote island off the southern coast of Thailand, during the region's dangerous monsoon season. Executive producer Mark Burnett is promising that the show will include brand new challenges, new rules and new twists like nothing ever seen in previous installments. As the castaways are faced with harsh weather and the uncertainty of what's coming next, each person must attempt to outwit, outplay and outlast the others in order to become the ultimate survivor.

In the US last season both Survivor: Africa and Survivor: Marquesas finished in the top 5 in viewers and placed fifth and sixth in adults 18-49. The latter averaged 20.8 million viewers (#4) while the former averaged 20.7 million viewers (#5). In adults 18-49 the former ranked #5 for the season with an 8.4 rating, followed by the latter at #6 with an 8.3 rating.
