The seaplane that plunged into a river north of Sydney on Monday, killing all six people on board, was involved in another deadly crash 22 years ago.
Police have now retrieved the wreckage of the plane, four days after it crashed.
The plane pieces could hold the clues as to what caused the crash, which killed all six people onboard - pilot Gareth Morgan and five UK tourists.
The plane was being used as a crop duster in 1996 when it cartwheeled and crashed, killing the pilot.
The wreckage of the latest crash is now being sent to Canberra for analysis.
Police say they are also looking into the pilot's background. An autopsy has been carried out looking for a cause of death, and whether a medical event or drugs or alcohol caused him to lose control.
