1983 - A vast dust storm sweeps across Melbourne, Australia.

Australia is regarded as the driest continent on the Earth, and dust storms are common in its interior.

Occasionally, particularly in times of prolonged drought, dust storms will also affect coastal areas. 1982 was the driest year on record for the Mallee and northern Wimmera district in Victoria, and as vegetation was killed off by the heat and lack of water, the topsoil was exposed and loosened.

By early 1983, Victoria had reported numerous smaller dust storms in its northwest.

On 8 February 1983, a strong, dry cold front began crossing Victoria, preceded by hot, gusty northerly winds. The wind picked up the loose topsoil and, raising a dust cloud 320m deep, advanced towards Melbourne, already suffering a record February maximum temperature of 43.2°C.

The dust storm hit the city around 3pm, dropping the temperatures dramatically, whilst wind squalls uprooted trees and unroofed houses. Visibility dropped to around 100m as the storm dumped approximately 1,000 tonnes of topsoil on the city.

The total mass of the 1983 Melbourne dust storm was estimated to be about two million tonnes: at its height, it extended across the entire width of Victoria, and was several kilometres deep.

The cost of the damage of drought and dust storm combined was ultimately tens of millions of dollars.
