Leave it to The Washington Post to uncover the identities of the 16 contestants for CBS’s “Survivor: The Australian Outback,” the sequel to last summer’s TV phenomenon. The Post after all, was the paper that uncovered the Watergate scandal, thanks to its unnamed source Deep Throat. Now it turns to Peter Lance, author of “The Sting Ray: Lethal Tactics of the Sole Survivor” and webmaster Tim Gillman, of Survivornews.net, who say that a source dubbed “Deep Kangaroo” has named Amber Brkich, 22, a student from Pennsylvania; Nick Brown, 25, of Washington; Alicia Calaway of Connecticut; Colby Donaldson of Texas; Debb Eaton of New Hampshire; Keith Famie, a Michigan chef; softball player Elisabeth Filarski, 23; Kel Gleason; Jeff Varner; Tina Wesson; Rodger Bingham; Maralyn Hershey; TV production freelancer Kimmi Kappenberg, from Long Island, N.Y.; Los Angeles actress Jerri Manthey, 30 (she appeared in Showtime’s “That Championship Season”); musician-writer Mitchell Olson, 23, who now lives in New Jersey; and Michael Skupin, a family man from Michigan. CBS would not comment on the show or on the purported findings. “Survivor: The Australian Outback” is set to premiere Jan. 28 after Super Bowl XXXV.
