The report of the Commission of Inquiry into the sinking of the Rabaul Queen has been presented to the Papua New Guinea caretaker Prime Minister.
The commission, which sat in April and May, is tasked with finding out what caused the tragedy, in which more than 140 people are believed to have dies.
It heard allegations of arrogance, apathy, complacency and incompetence from the company and captain of the ship.
The commission's website says the final report was presented to the Prime Minister yesterday.
It says it is the prerogative of the Prime Minister as to when the report is to be released, but it is expected that will occur soon.
