PERTH, Australia — A second person missing in the Australian outback for almost two weeks was rescued on Tuesday, while the police said Wednesday they may have found the body of a third member of the group.

The Northern Territory Police said that the rescued man, Phu Tran, was found by a livestock farmer south of Alice Springs in central Australia. He was taken to a hospital to be treated for exposure.

Pauline Vicary, the police superintendent, said Mr. Phu had told the farmer he had survived after finding some water.

Mr. Phu and two other people, Tamra McBeath-Riley and Claire Hockridge, had set out from Alice Springs for an afternoon drive on Nov. 19 when their vehicle got stuck in a riverbed in the arid region.
