While oak traditionally marks an 80-year milestone, it was steel, concrete and ingenuity that took centre stage at Fleet Base East as the Captain Cook Graving Dock celebrated its 80th anniversary.
On March 24, Defence and industry members united to honour an engineering marvel that has been the cornerstone of Australia’s naval capability since entering service in 1945 at the height of World War 2.
Director General Major Surface Ships Commodore Jason Sears highlighted the dock’s enduring importance.
“Even after 80 years, the Captain Cook Graving Dock remains a vital component of Australia’s sovereign defence capabilities,” he said.
“It is the largest graving dock in Australia and the only facility capable of accommodating all Royal Australian Navy vessels, as well as most commercial ships visiting our shores. Ensuring its continued success requires a strong partnership with industry.”
A symbol of Australia’s commitment to self-reliance, the dock’s construction was a feat of engineering.
More than 4000 workers at peak construction dredged 150,000 cubic yards of silt – enough to fill 60 Olympic-sized swimming pools – to create the facility.
Built as part of Australia’s wartime infrastructure expansion, it was one of the largest graving docks in the southern hemisphere at the time and played a crucial role in supporting allied naval operations in the Pacific.

Commanding Officer HMAS Kuttabul Captain Rebecca Levitt acknowledged the dock’s ongoing significance.
“It remains one of Australia’s most critical assets, particularly as our fleet expands,” she said.
“Sharing the facility with civilian industry strengthens our broader partnerships and ensures the dock continues to support Defence and commercial needs.”
The dock’s historical and engineering significance was formally recognised in 2021 when Engineers Australia designated it a National Engineering Landmark.
As part of the anniversary celebrations, the youngest dock worker, Kyle Creighton, cut the birthday cake.
“Working here has been an eye-opening experience,” he said.
“I’ve learned invaluable skills, met incredible people, and the location – right near the Sydney Harbour Bridge – makes it even more special.”
Commemorating this milestone was not only about reflecting on history, but also recognising the dock’s ongoing role in safeguarding Australia’s national interests.
In an increasingly complex strategic environment, the facility remains essential to maintaining the readiness and resilience of Navy.
