Water buffalo were imported to Australia in the 19th century to supply meat to remote northern settlements. The settlements and their buffalo were abandoned in 1949 and, despite harvesting for meat, hides and as hunters' trophies, feral buffalo spread across the northern floodplains. The Brucellosis and Tuberculosis Eradication Campaign reduced feral buffalo numbers significantly in the 1980s and 1990s but numbers are again very high right across northern Australia causing significant damage to wetlands. The buffalo like a wet habitat and graze early mornings and late evenings but spend the majority of their day times in the shade of a river bed wallow or flood plane wetlands
