A historic WWII warship was abandoned in 1972: Five decades later, it’s a ‘floating forest’ off the coast of Sydney
Once a coal ship and later a U.S. military supply vessel, the SS Ayrfield is now one of Sydney’s most remarkable hidden attractions.

If you’ve ever been to Sydney, Australia, there’s a good chance you visited the city’s most famous attractions, including the Sydney Opera House, Sydney Harbour Bridge and Bondi Beach. But you may well have missed one of its more unusual sights and best-kept secrets, the SS Ayrfield shipwreck.
Built in the United Kingdom in 1911 and initially named the SS Corrimal, the vessel was transported across the world and put to work the following year as a steam-powered collier in Sydney.
Thirty years later, at the height of World War II, the Australian government repurposed the ship as a troop supply carrier for U.S. forces in the Pacific.
From coal carrier to wartime service
The SS Corrimal changed hands several times after that. In 1951, its new owners renamed it the SS Ayrfield, and it returned to its role as a coal carrier. It continued in that service until the start of the 1970s, when it was retired.
Sixty years a ship. Fifty years a forest.

Built in 1911, the SS Ayrfield served as a supply vessel during World War II before spending decades hauling coal along the coast. When it was finally retired in 1972, it was towed to a scrapping yard to be broken apart.

The ship was left in Homebush Bay, a suburb neighboring Sydney Olympic Park. Before the 1980s, the area was largely industrial, consisting mainly of mangrove wetlands and salt marshes. Redevelopment transformed the waterfront into a mix of commercial and residential areas, but visitors also make the trip to see the SS Ayrfield resting in what was once a ship-breaking yard.
A shipwreck reclaimed by nature
The vessel, which is 72.8 meters (239 feet) long and weighs about 1,034 tons, is one of several shipwrecks in Homebush Bay. What makes it stand out is the extraordinary way nature has reclaimed it.
Stationed just a few meters from shore, the abandoned ship has become entwined with mangrove trees, which thrive in shallow coastal waters across tropical and subtropical regions. Their tangled roots and dense canopy have wrapped around much of the vessel, whose engine section has long since been removed.
Now, the SS Ayrfield’s only passengers are an eclectic mix of birds, animals and plants. That said, don’t be surprised to find photographers, history buffs and ship enthusiasts nearby if you happen to be in town and decide to make the short trip from downtown Sydney.
