Stay alert to Bureau of Meteorology warnings and have an emergency plan ready, because extreme weather events in Australia are becoming more frequent and intense, with bushfires, floods and cyclones posing greater risks to communities nationwide.

What counts as an extreme weather event?

An extreme weather event is when conditions deviate sharply from the historical average, causing significant disruption or damage. Common extreme weather events examples include tropical cyclones, severe thunderstorms, heatwaves, bushfires and east coast lows. In Australia, these events are often linked to natural climate drivers such as El Niño–Southern Oscillation and the Indian Ocean Dipole.

How have extreme weather events changed recently?

Extreme weather events in the last 10 years have shown a clear upward trend in intensity and frequency. Heatwave records are being broken more often, while heavy rainfall events are becoming more severe in many regions. The Black Summer bushfires of 2019–20 and the 2022 eastern Australia floods are stark reminders of the growing impact. Climate scientists link these shifts to a warming climate, making extreme weather events around the world more common.

Annual costExtreme weather now costs Australia roughly $38 billion per year in damages and lost productivity
Cyclone averageAustralia sees about 11 tropical cyclones each season, with 4–5 making landfall
Bushfire seasonFire danger season has lengthened by 4 months in some southern regions since the 1970s
What should I do during a cyclone warning?

Secure loose outdoor items, fill your car’s fuel tank, charge devices and move to the strongest part of your home – usually a small interior room. Follow all evacuation orders from local authorities immediately.

How can I prepare for a heatwave?

Stay hydrated, avoid outdoor activity during peak heat, and check on elderly neighbours. Keep your home cool with blinds drawn and use fans or air conditioning. Know the signs of heatstroke: confusion, red dry skin, rapid pulse.

Where can I find real-time warnings?

The Bureau of Meteorology issues official warnings for severe weather, floods and cyclones. Check the weather warning page for your area, or use the weather radar to track storms as they develop.
