ADMIRAL WILEY
Why dive here
With 241+ marine species recorded in the area - including barracuda, blacktip reef sharks, grey reef sharks, sea turtles and sperm whales - ADMIRAL WILEY offers some of Milne Bay's richest wreck diving. Water sits around 31°C.
Admiral Wiley is more than just a wreck; it’s a time capsule off Kitava Island, and frankly, one of our favourite dives in Milne Bay. This 98-metre steamship, built in 1920, lies broken but still impressive. We love tracing the deck, noting the sheer scale, imagining the roar of those turbine engines before she went down. You’ll find schools of batfish here, curious and unafraid, often circling the superstructure as you descend. Look closely and you'll spot pygmy seahorses clinging to gorgonian fans near the deeper sections. The hull plates themselves are encrusted with colourful soft corals, a genuine explosion of reds and purples. We’d suggest focusing on the bow section first; the coral growth there is particularly lush, and the light often catches it just right in the morning. While the visibility can vary, on a good day, the wreck reveals itself gradually, loomimg out of the blue, making the dive genuinely atmospheric. It's an excellent dive for those who appreciate history intertwined with vibrant reef life.

ADMIRAL WILEY Wreck History

Cause
grounding
The SS Admiral Wiley was a classic example of early 20th-century American shipbuilding. Constructed in 1920 by the Submarine Boat Corporation of New Jersey, she was a standardized steam-powered cargo ship, part of a massive post-WWI effort to expand the U.S. merchant marine fleet. For years, she plied trade routes under the ownership of the American Trading & Shipping company, a workhorse of the sea carrying goods across the globe.
Her final voyage came to an abrupt end in the tropical waters of Papua New Guinea. While navigating the channels near Milne Bay, a region famous for its complex reefs and passages, the Admiral Wiley ran hard aground on Kitava Island. The forces of the ocean and the reef were unforgiving, and the vessel was declared a total loss, left where she came to rest. With a depth listed as 0 meters, the wreck remains partially exposed, breaking the surface of the water as a permanent, rusting monument to her final mistake.
For divers and snorkelers, the Admiral Wiley offers a uniquely accessible experience. The shallow, submerged sections of the hull have blossomed into a spectacular artificial reef, teeming with the vibrant coral and fish life that Milne Bay is renowned for. The dramatic sight of the ship's bow or superstructure jutting from the turquoise water provides a stunning backdrop for underwater exploration. It is a photographer's dream, blending maritime history with the raw beauty of a thriving marine ecosystem, and a must-see site for anyone visiting the historic waters of Kitava.
