The name of the third person missing in a helicopter in dense forest in Papua New Guinea's Highlands has been released.
He is Emmett Fynn, a 36-year-old aircraft maintenance engineer from Australia.
The names of the pilots - New Zealander Anthony Annan, 49, and 42-year-old Russell Aitken from Australia - were released on Sunday night.
At the time Mr Fynn's family asked his name not be released, but have since changed their minds.
A third day of searching failed to find any sign of the men on Monday.
Searchers say they will use a helicopter fitted with a magnetometer on Tuesday. They hope its sensor, used to detect large mineral deposits, will pick up metal from the missing aircraft.
