Mysteries of the sea
The ocean’s depths hold an irreplaceable repository of our maritime heritage. In Australian waters, this seafaring past comes alive through legendary vessels that continue to captivate historians and divers alike.
Among these treasures is the aircraft carrier HMAS Melbourne, famed for her dramatic peacetime collisions, and the ill-fated coastal steamer SS Coramba, which tragically vanished during a fierce 1934 gale. While many ships succumbed to the deep or the scrapyard, the beautifully preserved corvette HMAS Castlemaine stands proud in Williamstown, offering a tangible link to World War II heroism.Hmas AE2
Woven with threads of adventure, tragedy, and unmatched bravery, these ships are far more than rusted steel and weathered timbers; they are timeless subjects of national identity. By exploring their wrecks and conserving their hulls, we honor the stories of those who sailed them, ensuring these vital chapters of maritime history inspire future generations.
Commissioned in 1914, the Royal Australian Navy E-class submarine Hmas AE2 made history alongside her sister ship, AE1, by completing the longest submarine transit of its time—a grueling voyage from Britain to Australia.
Wartime Service
During World War I, AE2 patrolled the Pacific before transferring to the Mediterranean. In the Gallipoli Campaign, she became the first Allied submarine to breach the heavily defended Dardanelles strait. Entering the Sea of Marmara, she spent five days harassing Ottoman supply lines and enemy shipping, significantly boosting Allied morale during the beach landings.
Legacy and Preservation
Mechanical failures and enemy damage eventually forced the crew to scuttle the vessel; while all crew members survived to become prisoners of war, AE2 remains the only RAN vessel lost to enemy action during WWI. Discovered in 1998, the wreck is preserved in situ under a joint Australian-Turkish agreement, serving as an enduring symbol of shared history and bravery
Commissioned during World War II, the Bathurst-class corvette Hmas Castlemaine defended Australian waters. Her wartime service included convoy escorts, anti-submarine warfare, and coastal patrols.
As the conflict escalated, she deployed to the front lines. She served in the New Guinea and Timor campaigns. There, she provided critical operational support to Allied forces.
Following the war, the Castlemaine briefly served as a training vessel. She trained the Royal Australian Navy Reserve. She was decommissioned in late 1945.
Most of her sister ships were scrapped or sold. However, the Maritime Trust of Australia saved the Castlemaine. Decades of meticulous restoration successfully returned her to her authentic wartime configuration.
Today, she is permanently berthed as a museum ship. You can find her at Gem Pier in Williamstown, Victoria. HMAS Castlemaine serves as an educational time capsule.
Visitors can explore her decks, engine rooms, and living quarters. This offers a firsthand look into the lives of wartime crews. She remains a proud, enduring tribute to Australia’s brave sailors. She stands as a tangible piece of the nation’s naval heritage.
The cruiser’s wartime service spanned the Mediterranean, Indian, and Pacific Oceans, focusing on three critical mission types:
Convoy Protection: Guarding vital Allied troop and supply lines across the globe.
Surface Combat: Hunting enemy raiders and engaging hostile warships.
Amphibious Support: Delivering devastating naval gunfire during key Southwest Pacific landings.
Australia proved incredibly resilient on the front lines. She survived severe damage from multiple kamikaze strikes later in the war and endured the tragic loss of her sister ship, HMAS Canberra, at the Battle of Savo Island in 1942.
Decommissioned in 1954, the battle-scarred “Aussie” left behind a legendary heritage of courage, determination, and sacrifice that remains bedrock to Australian naval history.
The collision between HMAS Melbourne and HMAS Voyager occurred on February 10, 1964. It remains the most devastating peacetime disaster in Royal Australian Navy history.
The ships were conducting night-flying exercises off Jervis Bay. Voyager was acting as the “plane guard” destroyer. She was positioned to the rear left of Melbourne to rescue downed aircrew.
Following a series of tactical turns, Voyager ended up ahead and to the right of the carrier. To return to her proper station, standard protocol dictated a specific move. Voyager had to turn away from the carrier and loop safely behind Melbourne’s stern.
Instead, Voyager unexpectedly swung left. She cut directly across the carrier’s bow.
Melbourne’s bridge crew initially assumed the destroyer was executing a standard tactical maneuver. They thought she would let the carrier pass.
However, it was a fatal misunderstanding. Modern analyses suggest Voyager’s Officer of the Watch became spatially disoriented.
He was manually calculating the ship’s relative position in the dark. This led to the catastrophic turn that cut the destroyer in two.
