Tasman Bridge Disaster: Lake Illawarra Collision on Jan 5 1975
The bulk carrier Lake Illawarra struck a bridge over the River Derwent in Hobart, Tasmania, Australia, causing the deaths of seven of the ship's crewmen and five motorists on the bridge.
On the evening of January 5, 1975 a handysize bulk carrier named Lake Illawarra hit pylon 19 of Hobart's Tasman Bridge. The collision caused the deaths of seven crew members and five motorists, marking one of Tasmania's worst transport disasters.
The ship and the bridge
Lake Illawarra was a 7,274‑ton bulk ore carrier operated by the Australian National Line. The Tasman Bridge, a high concrete arch spanning the River Derwent, was Hobart's main crossing over the estuary.
At 9.27 pm on January 5 the vessel struck the bridge’s nineteenth pylon. The impact broke the bridge and sent debris onto the roadway below.
Human toll of the disaster
The crash killed seven of the ship’s crew and five motorists who were on the bridge at the time. In total, twelve lives were lost.
Rescue efforts focused on retrieving victims from the water and the broken bridge sections, highlighting the vulnerability of both maritime and road traffic in the narrow Derwent estuary.
