Sydney, Dec 20 (IANS): The final pictures taken on-board a seaplane which plunged into a river in 2017, killing six people, have been released.

The DHC-2 Beaver was on a sightseeing flight when it nose-dived into the Hawkesbury River at Jerusalem Bay, about 50 km from the city centre, the BBC reported.

Five members of a British family and a Canadian pilot died in the incident north of Sydney on December 31.

On Wednesday, the Australian Transport Safety Bureau (ATSB) released photos that had been recovered from a camera and a phone on-board.

Australian investigators said photos and witness accounts helped them reconstruct the flight's final moments.

They were able to use images taken by the front seat passenger to recreate the flight path, the ATSB said.

Most of the wreckage was recovered in January but it was still not clear as to what caused the crash.

The ATSB will release its final findings and recommendations sometime in the next six months.
