Indonesian authorities said the helicopter was collecting water using a suspended bucket when it lost control and plunged into the river.

The aircraft was carrying three crew members, believed to be an Australian, a New Zealander and an Indonesian national.

The Australian and New Zealander were rescued, while the Indonesian crew member died.
