The 2009 southeast Queensland oil spill occurred off the coast of southeast Queensland, Australia on 11 March 2009, when 230 tonnes of fuel oil, 30 tonnes of other fuel and 31 shipping containers containing 620 tonnes of ammonium nitrate spilled into the Coral Sea, north of Moreton Bay during Cyclone Hamish. It happened after unsecured cargo on MV Pacific Adventurer damaged other cargo, causing the spillage.
