A search is under way for five people, including a child, missing in the Torres Strait.
Queensland police are yet to determine whether a child's body found in Papua New Guinea belongs to one of five people missing from an empty boat found floating in the Torres Strait.
The nine-year-old, two men and two women set off from Badu Island for Dauan Island on July 31, but never arrived.
Their empty boat, a seven-metre vessel, was found on Friday afternoon about 4.5km west of Dauan Island.
Papua New Guinea authorities have located a child's body on the coast near Old Mawatta Village on the mainland.
Queensland Police are determining if the body is that of the missing boy, but said it was found outside the search area.
A rescue helicopter on Saturday also located a bag containing life jackets, which will now be tested to determine if they came from the boat in question.
Water police and the helicopter will concentrate their search on the coastlines of the islands within the Torres Strait.
