Port Lincoln saw the HMAS Melbourne visit over the weekend for one of her final port visits before she is decommissioned later this year.
The 138-meter-long warship pulled alongside the Port Lincoln Wharf on Friday and visited for three days.
The ship travelled from Tasmania and will head towards Adelaide next.
The HMAS Melbourne was commissioned in 1992 and has sailed more than seven hundred and eighty thousand nautical miles throughout her service life.
Commanding Officer Commander Marcus Buttler said the visit would be bittersweet as it marked another step towards Melbourne’s decommissioning.
The Navy shares a common thread with Port Lincoln through the local Navy Cadet unit, and is are linked to South Australia more generally through decades of shipbuilding.
Commander Buttler said “This includes constructing and maintaining our current submarine fleet, building three new Air Warfare Destroyers, and producing Australia’s first Hunter Class frigates and Offshore Patrol Vessels in the near future.
