The crash on Borneo Island's South Kalimantan province was the second in days involving a firefighting helicopter, after a military chopper plunged into the waters off Borneo on Wednesday, killing three people.

Two Australian nationals had survived Sunday's incident and were "safe", said Berton Panjaitan, a spokesman for the national disaster mitigation agency, while the third member of the crew, an Indonesian, remained unaccounted for.
