Investigators are set to examine a fishing trawler which capsized off the central Queensland coast in October, claiming six lives.
The Dianne overturned off the town of 1770 during stormy conditions, with authorities towing the vessel into the port of Bundaberg on Tuesday.
Inspector Pat Swindells said experts from Brisbane would help with the formal investigation to determine what caused the ship to capsize.
"Later on today they'll attempt to pump the Dianne out once it has been emptied of water," he said.
"Police will continue an investigation with specialist police coming from Brisbane and our detectives will continue to try and find out exactly what happened and how it sank.
"The way the actual vessel was sitting on the sea floor was very, very difficult for salvage to get it upright and bring it to the surface and they've done a magnificent job of bringing it up in one piece."
Ruben McDornan was the only person to be found alive after the boat overturned, with crewmen Adam Bidner, Zachary Feeney, Chris Sammut, Eli Tonks, Adam Hoffman and Ben Leahy killed in the tragedy.
The bodies of some of the men were not located in the aftermath of the incident.
"Police divers initially conducted a search of the Dianne, however this will be conclusive once we've emptied the water out and we've been able to conclusively say whether or not they're on board," Inspector Swindells said.
Premier Annastacia Palaszczuk the men and their families remained in the thoughts of the community.
"I pay tribute to all those involved the initial search, and those who have worked in the recovery efforts that now allow for thorough investigations into this tragedy," she said.ABC
