Aviation experts are working to determine what caused a seaplane to crash into a river north of Sydney, killing all six people on board, after it was recovered from the water following a complex operation.
The DHC-2 Beaver, which crashed into Jerusalem Bay on New Years Eve, was pulled from almost 15 metres of water on Thursday afternoon, revealing significant damage to the aircraft.
Police said the visible damage gave some insight into how hard it hit the water.
"From the time the wreckage was brought on the barge, we saw that there was severe damage to the plane, and it appeared there'd been quite an impact on hitting the water," Detective Superintendent Mark Hutchings told reporters on Thursday afternoon.
The wreckage of the plane was recovered on Thursday evening and placed on trucks before being driven to a secure facility, according to police.
They'll "carefully assess all aspects related to the aircraft's airworthiness", a spokeswoman said in a statement, adding the Australian Transport Safety Bureau would "examine in detail the history of this aircraft".
The ATSB is working to determine why the seaplane went down. One possibility is the plane stalled.
The Civil Aviation Safety Authority has confirmed the Beaver didn't have a stall warning system but also notes they aren't required in Australia.
The Beaver is a Canadian-built aircraft and the ATSB says its Canadian counterpart will assist during the 12-month investigation into Sunday's crash.
Experienced Canadian pilot Gareth Morgan died along with high-profile UK businessman Richard Cousins, his two adult sons Edward and William, his fiancee Emma Bowden and her 11-year-old daughter Heather when the plane plunged into the Hawkesbury River.
The brothers of Mr Cousins, Simon and Andrew, have arrived in Sydney and thanked both emergency services workers and the general public for their help.
"We are fortunate and thankful for the outpouring of love and support we've received from across the world," the brothers said in a statement to Ten News.
