Quick answer
To prepare for a natural disaster in Australia, work through four steps: know which hazards apply where you live, make a plan with a trigger for leaving, pack a kit you can carry, and learn the three warning levels. The decision that matters most is deciding in advance what will make you go — because the moment itself is when people hesitate.
Australia gets bushfires, floods, cyclones, severe storms and heatwaves, and most of us live somewhere exposed to at least one. Preparation is not about expecting the worst. It is about not having to make good decisions quickly while frightened.
What we actually get here
- Bushfire — most of southern and eastern Australia, with a season that varies by region.
- Flood — the most widespread hazard, including flash flooding well away from rivers.
- Cyclone — northern Australia, roughly November to April.
- Severe storm — anywhere: hail, damaging wind, lightning, blackouts.
- Heatwave — the one people underrate. Heatwaves cause more deaths in Australia than other natural hazards, and they do it quietly, without a visible emergency.
Step 1: Know your risk, specifically
“Somewhere in the suburbs” is not a risk assessment. Find out what applies to your street:
- Is your property in a bushfire-prone area, and where would fire come from?
- Has your street ever flooded? Ask a long-term neighbour, not just a map.
- Do you rely on power for anything medical — oxygen, a pump, refrigerated medication?
- How many ways are there out of your suburb? Some have one.
Your state emergency service publishes local hazard information — for example NSW RFS, NSW SES and CFA in Victoria.
Step 2: Make a plan, with a trigger
Most plans fail on one point: they say what to do but not when. Decide the trigger now, while it is abstract.
Settle these in advance
- What makes us leave? A warning level, a forecast, a smell of smoke — name it.
- Where do we go, and what is the second option if that road is closed?
- Who collects whom, including school pick-up?
- How do we contact each other if the mobile network fails?
- What happens to the pets and livestock? Plans that ignore animals are the ones people abandon.
- Who needs help — an elderly neighbour, someone with limited mobility?
For bushfire specifically, leaving early is consistently the safest option. Deciding to stay and defend requires preparation, equipment and physical capacity that most households do not have.
Step 3: Pack a kit you can actually carry
| Category | Contents |
|---|---|
| Water and food | Drinking water and non-perishable food for several days |
| Medical | First aid kit, at least a week of medications, scripts, a written medication list |
| Power and light | Torch, spare batteries, power bank, battery radio |
| Documents | ID, insurance, Medicare, copies stored separately or online |
| Protection | Sturdy shoes, long cotton clothing, gloves, P2 mask, hat |
| Comfort | Blanket, cash, phone charger, something for the kids |
Two details people miss: a battery radio, because when the power and the mobile network go, radio is what still works — ABC Emergency is the designated emergency broadcaster. And medication, which is the item most often left behind and hardest to replace mid-evacuation.
Step 4: Learn the three warning levels
Australia now uses one national scheme, the Australian Warning System, across bushfire, flood, storm, heatwave and severe weather. The wording is the same wherever you are.
| Level | What it means | What to do |
|---|---|---|
| Advice (yellow) | An incident has started; no immediate danger | Stay informed in case it changes |
| Watch and Act (orange) | Heightened threat; conditions are changing | Start acting now — this is the level people wait through |
| Emergency Warning (red) | The highest level | Act immediately; you may already be in danger |
Get warnings from more than one source: your state emergency service app, the Bureau of Meteorology, and ABC local radio.
If it’s flooded, forget it
Never drive, ride or walk through floodwater. You cannot see whether the road is still there, how deep it is, or how fast it is moving, and cars are swept away in surprisingly shallow water. Driving into floodwater is one of the commonest causes of flood deaths in Australia, and almost all of it is avoidable.
The medical side of an evacuation
This is where preparation quietly falls over. People remember the dog and the photo albums, and leave the medication on the kitchen bench.
- Keep a week’s medication in the kit, rotated so it does not expire.
- Carry a written medication list — an evacuation centre or unfamiliar pharmacy cannot see your records. See how to manage your medication.
- Plan for refrigerated medicines and power-dependent equipment before there is a blackout.
- If you have a chronic condition, factor it into the leave-early trigger — see staying safe in an emergency with a chronic condition.
- Keep your details on you, not only in a phone that may be flat with no way to charge it — see what to put on a medical wristband.
In an evacuation, your records will not be where you are.
A MedibandPlus profile keeps your conditions, medications and contacts readable from a membership number you wear — no app, no login, nothing to pack.

Heat deserves its own plan
Heatwaves cause more deaths in Australia than other natural hazards, and they are the easiest to dismiss because nothing appears to be happening. Older people, very young children, people with chronic conditions and outdoor workers are most at risk.
- Identify the coolest room, and plan to spend the hottest hours there.
- Check on older neighbours and relatives daily during a heatwave, not once.
- Know that some medications affect how the body handles heat — ask your pharmacist rather than guessing.
- Never leave anyone, or a pet, in a parked car.
Recognising heat illness matters as much as avoiding it — see heatstroke and heat exhaustion first aid.
Afterwards
- Do not return until told it is safe. Fallen powerlines, damaged structures and contaminated water do not look dangerous.
- Photograph damage before you clean up, for insurance.
- Assume floodwater-contacted food and water is unsafe.
- Replace what you used from the kit straight away.
- Expect the emotional part. Australian Red Cross offers recovery support, and it is normal to need it.

FAQs
How do I prepare for a natural disaster in Australia?
Work through four steps: find out which hazards apply to your specific address, make a plan that includes a named trigger for leaving, pack a kit you can carry that includes at least a week of medication, and learn the three national warning levels. The most valuable part is deciding in advance what will make you leave.
What are the three Australian warning levels?
Advice, shown in yellow, means an incident has started with no immediate danger, so stay informed. Watch and Act, in orange, means a heightened threat with conditions changing and you should start acting now. Emergency Warning, in red, is the highest level and means act immediately. The same wording is used nationally across bushfire, flood, storm, heatwave and severe weather.
What should be in an emergency kit?
Drinking water and non-perishable food for several days, a first aid kit with at least a week of your medications plus scripts and a written list, a torch with spare batteries, a power bank, a battery radio, copies of ID and insurance documents, sturdy shoes and long cotton clothing, gloves, a P2 mask, a hat, a blanket and some cash.
Why is a battery radio still recommended?
Because when mains power and the mobile network fail, radio is often what still works. ABC local radio is the designated emergency broadcaster in Australia, so a battery or wind-up radio gives you a warning channel that does not depend on your phone having charge or reception.
Can I drive through floodwater if it looks shallow?
No. You cannot see whether the road surface is still there, how deep the water is, or how fast it is moving, and vehicles are swept away in surprisingly shallow water. Driving into floodwater is one of the commonest causes of flood deaths in Australia, and nearly all of those deaths are avoidable.
How do I manage medication during an evacuation?
Keep at least a week's supply in your kit and rotate it so it does not expire, carry a written medication list because an evacuation centre or unfamiliar pharmacy cannot see your records, and plan ahead for anything refrigerated or power-dependent. Medication is the item most often left behind and the hardest to replace mid-evacuation.
Why do heatwaves need their own plan?
Because heatwaves cause more deaths in Australia than other natural hazards, and they are easy to dismiss since nothing visible appears to be happening. Identify the coolest room and use it during the hottest hours, check on older neighbours daily rather than once, and ask your pharmacist whether any of your medications affect how your body handles heat.
