Severe storms in Australia refers to the storms, including cyclones, which have caused severe damage in Australia.
On 26 January 1971 a severe storm caused flash-flooding on the Woden Valley freeway when culverts became blocked with debris at either end. Several cars were swept from the road into the rushing water. Seven people were killed, 15 were injured, and 500 people were affected by the 1971 Canberra flood. Insurance damage was estimated at $9 million (1971 dollars). Significant rectification works was undertaken at Yarra Glen.
Five people were injured in the suburb of Chisholm in 1990 by a tornado which destroyed a wooden church and damaged 37 houses.
27,000 people were affected across the territory by a severe storm in November 1996.
There were heavy storms (and a possible tornado) which hit Canberra, and the surrounding New South Wales region, on 2 December 2005. The storms were the worst emergency to hit Canberra since the 2003 Canberra bushfires. The storms caused much damage to houses and property, and one man was killed by a falling tree in the suburb of Curtin. The storm hit Canberra at about 4.30 pm, and moved south-eastwards across the city. There were 51 Canberra suburbs which reported damage during the storm, the most extensive being in Fyshwick estimated to be A$3–4 million in damage. The ACT Emergency Services received about 200 calls for help during the storm, with the NSW SES getting more than 500 calls. Calvary Hospital, and thousands of houses lost power, with ACTEW saying that about 5% of the network had been affected. Calvary utilised a generator until power was restored. The storm was rated as one of the biggest ever to hit the ACT, with an estimated A$15 million in damages across the city.
On 31 December 2006 a huge thunderstorm, the third in three days, caused havoc in the southern part of Canberra – inner suburbs and Tuggeranong.
