The family of a young diver killed in a training exercise say the Navy has ruined their lives.
The Defence Force has been fined close to $300,000 - having admitted responsibility for the death of Zachary Yarwood.
The Devonport Naval base sat peacefully in the sunshine on Friday with no trace of the tragedy that unfolded here in March 2019.
The pain though is firmly etched into the hearts of those who miss Yarwood the most.
His mother, Elizabeth Yarwood, says she has recurring dreams of her son at the bottom of the sea.
His fiancée - Emily Parr, has lost her best friend.
"I've lost our future plans. I've lost our wedding day. I've lost the future kids we planned on having."
Through tears, they remembered an extraordinary young man - but also a trainee diver who they say was pressured by his navy superiors into operating in unsafe conditions during a week of endurance training.
He got into trouble during a late night diving exercise - there were only two supervisors present when there should have been four.
WorkSafe charged the Defence Force under the Health and Safety act for failing to ensure the safety of its employees.
In July the Defence Force pleaded guilty. This afternoon - it was fined $288,000.
David Proctor, the chief of Navy says he can't bring Zach back.
"But I can commit to making change for the future."
An apology - not accepted by Zachary's mother.
"They have simply ruined all our lives."
