The ice was so heavy, a newly built roof of the shopping centre collapsed. Birds were killed by hail produced from the supercell (Northbourne Avenue), and people were stranded. The following day (28 February) many homes in Canberra were subjected to flash flooding, caused either by the inability of storm water infrastructure to cope, or through mud slides from cleared land. November to February is traditionally the thunderstorm season. As reported by the Bureau of Meteorology, February 2007 had a record number of thunderstorms.

Queensland

Tropical Cyclone Sigma caused destruction from Townsville to Brisbane between 24–27 January 1896. 18 people were killed, most of whom lost their lives when a storm surge caused a breach of the Ross River on 26 January, travelling 3 miles upstream, and flooding parts of Townsville to a depth of 2 metres.

, in March 1899, resulted in the greatest death toll of any natural disaster in Australian history. Over 400 people lost their lives. The storm decimated a pearling fleet at Bathurst Bay in Queensland and deaths included the crews of around 100 vessels and an estimated 100 local aboriginals, who were swept out to sea while trying to save shipwrecked crew.

Two of the country's strongest cyclones occurred on the North Queensland coast in 1918. The Mackay Cyclone struck Mackay and surrounding regions in late January 1918, in addition to a devastating storm surge and extensive flooding. A Category 4 cyclone with barometric pressure at the eye as low as 933 hPa, Mackay and Rockhampton experienced the death of some 30 people, hundreds of injuries, and $60 million damage. Of the approximate 1400 homes in the Mackay township, 1300 were destroyed or severely damaged.

10 March 1918 saw an even stronger cyclone and storm surge cross the coast at Innisfail, with further desolation at Cairns, Babinda, and on the Atherton Tableland. Barometric pressure measured from outside the cyclone eye was recorded at 926 hPa. Estimates based on height of the storm surge suggest the 1918 Innisfail Cyclone was a "super typhoon" with pressures below 900 hpa at the eye, however recording equipment at the storm centre was badly damaged so an accurate minimum could not be obtained. 37 people perished in the township of Innisfail, with a further 40-60 Aboriginals estimated to have died in outlying areas. With a population of 3,500, Innisfail saw only 12 houses remain unscathed.

A Cyclone in Northern Queensland killed 99 people over two days in mid March 1934.

The Gold Coast Cyclone struck the Gold Coast on 20 February 1954. Four people were killed during the cyclone, while a further 22 died in the resulting floods around Lismore in Northern New South Wales.

Areas were declared disaster zones, with one of the worst hit areas being The Gap, a north-western suburb, where roofs were lifted off houses, trees were uprooted, and cars were destroyed by falling debris, destruction typical of tropical cyclones. Recovery efforts were hampered as further storms continued throughout the week.

December 2003

A severe weather event occurred over the city of Melbourne, Australia, and surrounding areas of Victoria, from 1 December to 6 December 2003. The storm formed at around midnight on the night of 2 December. The two hours from midnight to 2 am saw extremely heavy rainfall, with some areas recording more than 100mm of rain in that time. The rapid rain fall caused flash flood

ing, which resulted in extensive damage to property. At the time the Australian Bureau of Meteorology called the storm a "once in 100 year event", but similarly severe storms struck Melbourne in 2005 and 2010.

February 2005

An unusually intense low-pressure system developed over Eastern Bass Strait on 2 February 2005. After a spell of warm days with a north to north easterly airflow over much of eastern Australia, the region suffered the effects of one of the most intense summer time weather systems on record. Southern NSW, South Australia and Tasmania also received substantial rainfall during this event, however the highest rainfalls were concentrated in Victoria. The event made February 2005, Victoria's wettest February since 1973 and the 7th wettest in the last 106 years. The cold air associated with this system also assisted in the month of February in Victoria being its coolest since 1954. Many rainfall and temperature records were broken in the course of the event as the system passed across eastern Australia.

The system brought abnormally low temperatures and severe storms with gale and storm force winds to most parts of the region. However, the continuous rainfall for about 30 hours was perhaps the most significant feature produced by the low-pressure system. The rainfall resulted in widespread flooding, particularly over Central Victoria and West and South Gippsland. Unseasonable snowfalls were observed on the Australian Alps. Although low-pressure systems in February are not uncommon, the slow and westward moving nature of this particular system was extraordinary. The centre of the low developed and deepened over Melbourne with very little movement. The combination of extreme rainfall and lashing winds caused destruction.
Victoria is a high area for severe storms.

March 2010

6 March 2010 brought one of the worst hail storms to ever hit Melbourne. The storm occurred due to the collision of warm humid air moving southwards, and a cold front moving from the south-west. The resulting storms moved from north to south, wreaking havoc across Shepparton in the state's north, uprooting trees and damaging roofs. As the storms passed over central Melbourne they released large hailstones and very heavy rainfall, causing localised flash flooding and extensive property damage.
