The Ash Wednesday fires were an Australia n Natural Disaster which occurred on February 16 , 1983 . The fires affected much of Victoria , including the Dandenong Ranges , as well as the Otway Ranges in the south west. They also affected much of South Australia , mainly the Adelaide Hills , but also the Clare Valley and the pine forests of the state's south east. The fire was so severe that Firefighter s were unable to stop it, and the fire only came to an end when it reached the ocean on Victoria's south coast. Melbourne was encircled by fires and remained covered in smoke for weeks, requiring drivers to use their headlights in the city during the day time. Outer metropolitan areas of both Melbourne and Adelaide were threatened, particularly those suburbs located towards the Dandenongs in Melbourne. The smoke reached as far north as Batemans Bay, New South Wales . Much of Mount Macedon to the north west of Melbourne was devastated. Prior to these events south eastern Australia had experienced a prolonged drought caused by the El Niño climate events. Another precipitating factor was an ongoing fire in eastern Victoria that went uncontrolled for almost a month. The human loss was 75 lives: 47 in Victoria and 28 in South Australia. In the Dandenong Ranges, 17 Firefighter s also lost their lives while they were fighting the fires, on account of an Abrupt Change In Wind Direction . The Ash Wednesday fires were unusual in other ways too—a Mattress was seen flying out of control in the Otways. 2,545 individuals and families lost their homes. At the height of the blaze there were reports that fire fronts moved faster than 100kmh-1. {Link without Title} The total land burnt was approximately 2,100km&2 (518,921 acres) in Victoria and 2,080km&2 (513,979 acres) in South Australia. The summer bushfires of 1982/1983 razed approximately 5,200 km² (1,284,000 acres). In Victoria many fires were thought to have been caused by sparks between shorting power lines and or tree branches connecting with power lines. A systematic review of fire safety was undertaken: areas were cleared under high tension pylons and local domestic lines considered to be at risk were replaced with insulated 3 phase supply lines.
