MV Iron Baron (previously known as MV Ocean Express and MV Irrawaddy) was a 37,557 dwt bulk carrier constructed in 1985 and subsequently chartered by BHP Shipping in 1990.
On 10 July 1995, nearing the conclusion of a journey carrying 24,000 tonnes of manganese ore from Groote Eylandt through Port Kembla to Bell Bay, the ship ran aground on Hebe Reef located at the entrance to the Tamar River in northern Tasmania. The weather at the time featured north-westerly winds ranging between 37 and 46 km/h (20–25 knots) accompanied by two-metre waves. The grounding incident resulted in a leak of bunker fuel oil; however, the crew was evacuated without injury.
Salvage efforts commenced immediately, and by 13 July, casualties included one penguin and three cormorants, while approximately 200 penguins were rescued and placed under care.
After being refloated on 16 July and moved offshore, inspections revealed significant structural damage with ongoing degradation. Anticipating adverse weather conditions ahead, BHP opted to dispose of the vessel. It was subsequently towed to a designated site roughly 85 km east of Flinders Island and deliberately sunk on 30 July.
Environmental impact
Approximately 325 tonnes of heavy bunker fuel oil were released during the grounding, refloating, and towing phases. This spill affected multiple beaches and islands along north-eastern Tasmania, triggering an extensive cleanup operation alongside wildlife rescue initiatives.
Little penguins suffered considerable harm; a total of 1,894 oiled birds were treated and rehabilitated. At Ninth Island alone, fatalities ranged from 2,000 to 6,000 penguins. Initial estimates in 2001 suggested total penguin mortality between 10,000 and 20,000 individuals; this figure was later updated to approximately 25,000 based on a decade-long post-incident evaluation.
