The Defence Force has suspended three sailors over allegations of unacceptable behaviour on the Navy ship HMAS Ballarat.

Defence investigators say they have a “reasonable suspicion” that the three members have committed serious offences.

Chief of Navy, Vice-Admiral Ray Griggs, says there will be an inquiry into the allegations.

“I am very keen to remain as open and transparent as possible without compromising the investigative process,” he said in a statement.

“Due to the serious nature of these allegations, maintaining the integrity of the investigative process remains my principal concern.

“Navy does not tolerate unacceptable behaviour.

“It is inconsistent with its values and the behaviours.

“Unacceptable behaviour by individuals damages our people and our effectiveness to conduct operations and achieve our mission.”
