Investigators have since examined the wreckage, reviewed flight data, and analysed video footage, including witness recordings and CCTV.

The ATSB is expected to address media later this afternoon.

The tragic crash

The tragedy also left four others injured — the partners of the deceased tourists and a WA couple, who were all on board.

Survivors speak out

Police divers worked overnight in the 8-meter-deep waters to recover the victims, a task Police Minister Paul Papalia described as “difficult and confronting”.

The recovery process

Following the crash, an extensive ATSB investigation was launched, examining maintenance records, operational history, and potential human error.

Wreckage and flight data obtained from Cessna were carefully analysed, with key components flown to Canberra for further examination.

A final report, including findings and safety recommendations, will be released at a later date.
