Brisbane storms do not mess around. Sunny one minute. Hail and blackouts twenty minutes later.
South-east Queensland is a thunderstorm hotspot. October to March brings lightning, hail, rain, and wind to the Energex network. That is 1.5 million customers across Brisbane, Gold Coast, Sunshine Coast, Ipswich, and beyond. A bad storm can knock out power for hours or days – take Christmas 2023 as an example, which left over 200,000 Energex customers in the dark.
When the power goes out, the countdown begins for all the food you store inside. What you do in the first hour without power -- and when the lights come back -- decides how much you lose.
National Appliance Repairs gets a flood of fridge calls after every major Brisbane storm. Some for food safety. More for appliances fried by power surges when the grid comes back. The good news is that if you’re prepared, both can be avoided.
The Countdown Starts the Moment the Power Goes Off
The most important thing you can do during a blackout is also the simplest: keep the fridge and freezer doors closed.
According to the Northern Territory Government's food safety guidance -- consistent with Australia-wide standards -- a closed refrigerator should keep food cool for four to six hours, while a full freezer should keep food frozen for up to 48 hours, and a half-full freezer for up to 24 hours.
The moment you open the door, cold air escapes and warm air enters. In Brisbane's summer ambient temperatures -- often 28--32°C or higher -- that exchange happens fast. Every unnecessary door opening shortens the safe window significantly.
Write down the time the power went off. It sounds obvious, but in the disruption of a storm -- moving kids away from windows, checking on neighbours, finding torches -- it's easy to lose track. The time the power went off is the number you need to make food safety decisions later.
The 2-Hour / 4-Hour Rule
Here is the rule for hazardous foods, according to Food Standards Australia New Zealand: meat, chicken, fish, dairy, leftovers, anything ready-to-eat. If it sits between 5°C and 60°C (the danger zone):
- Under 2 hours? Fridge it or eat it now
- 2 to 4 hours – eat it immediately, do not put it back in the fridge
- Over 4 hours – Bin it
The clock counts total time above 5°C. So if your fridge hit 5°C two hours into the outage and stayed there for three more hours, throw that stuff out.
The catch? You usually do not know when the fridge crossed 5°C. A fridge that was 3°C and never opened might stay safe for over an hour. A fridge that was warm already or got opened a bunch of times? That crosses the line fast.
Only a fridge thermometer tells you for sure. No thermometer? When in doubt, throw it out.
What to Do During a Long Outage
If the power has been off for more than an hour and restoration looks unlikely soon, there are practical steps worth taking:
- Move perishables from the fridge to the freezer -- if you have space. The freezer's insulation is better and its safe window is much longer. Health Victoria recommends putting bagged ice under food packages and trays in freezers and fridges if the power failure lasts more than an hour.
- Use an esky (cooler) with ice bricks -- transfer meat, dairy, and other high-risk fridge contents into a well-sealed esky if alternative cold storage isn't available within 2 hours.
- Check with neighbours or family -- if the outage is localised to your street or suburb and a nearby relative has power, transporting perishables to their fridge is a legitimate option.
- Group fridge items together -- food packed together retains cold better than items spread out with air gaps between them.
- Don't put hot food into the freezer -- it raises the internal temperature and puts already-stored frozen food at risk.
What to Do When the Power Comes Back
Check food temps. Do not assume.
When the power comes back on, never assume everything is fine. Grab your thermometer and double check that:
- Freezer is really at 0°C or below? If so, refreeze or use. But if it’s above 0°C? Bin it.
- If you find the temperature of the fridge above 5°C:
- It’s fine to eat or keep if it’s been less than 2 hours since power went out
- Eat it now if it’s been 2 to 4 hours
- If it’s been more than 4 hours, then bin it
Do not plug the fridge back in straight away
Compressors do not like restarting under load. Most modern fridges have a delay relay, but older ones may not. You’ll want to wait for two to five minutes after power returns before switching the fridge on to save the compressor from a hard start, which can damage the compressor’s inner parts.
Look for surge damage
Grid restoration often comes with a voltage spike, and high voltage can fry the control board, the compressor, and the ice maker. See if you can spot any of these symptoms:
- Fridge runs but does not cool
- Weird or constant compressor noise
- Display dead or throwing errors
- Burning smell from the back
- Light works but compressor does not start
If you check off even one issue on this list, unplug the refrigerator and give National Appliance Repairs a call Running a damaged fridge can worsen the damage and make repair all the more complicated (and expensive).
What Is and Isn't Safe to Keep
Not all fridge contents are equally vulnerable. Use this as a guide when assessing what to keep after a long blackout:
| Category | Safe After 4+ Hour Outage? |
|---|---|
| Raw meat, poultry, seafood | No -- discard |
| Cooked meat, leftovers | No -- discard |
| Dairy (milk, soft cheese, yoghurt) | No -- discard |
| Hard cheese (Parmesan, aged cheddar) | Generally yes |
| Eggs in shell | Generally yes if still cool |
| Butter and margarine | Yes |
| Fruit juices, opened | Discard if above 5°C for 4+ hours |
| Fresh whole fruit and vegetables | Generally yes |
| Bread, peanut butter, jam | Yes |
| Frozen food with ice crystals still present | Can be refrozen |
| Frozen food fully thawed | Do not refreeze; use immediately or discard |
The principle throughout is: when in doubt, throw it out. Food poisoning in Brisbane's summer heat is a serious risk, and contaminated food often looks, smells, and tastes normal. There is no reliable sensory test.
Insurance: What's Covered
Food spoilage insurance covers loss of or spoilage to frozen or refrigerated food caused by an insured event. That could be a freezer breaking down, a power outage, or in some cases electrical motor damage. It is generally included in the contents section of a home and contents policy.
If you have lost significant food after a Brisbane blackout, check your policy's Product Disclosure Statement (PDS). Coverage limits for food spoilage commonly sit around $500 in standard policies, though this varies. Document what you have discarded with photos and a written list before throwing anything away. Then contact your insurer promptly.
If the fridge or freezer itself was damaged by a surge, that may be covered separately under home contents insurance or under a specific electrical surge or equipment breakdown provision. A technician's report documenting the nature and likely cause of the fault will support any claim.
How to Protect Your Fridge Before the Next Storm
Brisbane storm season runs from about October through March. And here is the thing. If you have been through one major outage, you will probably go through another. A few simple steps make a big difference next time.
Get a real surge protector. Not a cheap power board. A surge protector rated for large appliances. It plugs in between the wall outlet and your fridge. Its job is to protect against voltage spikes when the power comes back on. Standard power boards are not designed for a fridge's draw. You need one rated for large appliances with a joule protection rating of 1,000 or above.
- Buy a fridge thermometer: They cost a few dollars at any kitchenware store. Stick it inside. When the power goes out and comes back on, you will know exactly what temperature your food reached.
- Keep your freezer reasonably full: A full freezer stays frozen way longer than a half-empty one. If your freezer is usually pretty empty, throw a few containers of water in there. They freeze and add thermal mass and can buy you a few extra hours.
- Bookmark the Energex's outage map: Do it now before the next storm. It updates in near real time and gives estimated restoration times by suburb. When the power goes out, you will know whether it is a quick fix or a multi-day disaster. That helps you decide how seriously to treat the outage.
FAQ
How long does a fridge keep food safe in a Brisbane blackout?
Four to six hours. Brisbane heat means the four-hour window is the safer bet in summer. Keep the door shut. Note when the power went off. Use a thermometer if you have one.
Can I refreeze thawed food?
Only if you still see ice crystals or a thermometer says 0°C or below. Fully thawed? Do not refreeze. Cook and eat now or bin it. Refreezing food that sat in the danger zone is risky.
Fridge runs but does not cool after power came back. Why?
Classic post-surge damage. Likely the control board or compressor. Unplug it. Call a technician. Do not let it keep running as it’ll make the damage worse.
Does QLD insurance cover food lost in a blackout?
Many policies do and usually have a $500 cap – you can check your PDS for more details. Take photos and list what you threw out and call your insurer promptly. Storm blackouts are generally covered.
Food looks and smells fine. Is it safe after a long outage?
Not necessarily. Salmonella and listeria do not smell or look different. The time-and-temperature rule is the only thing you can trust: if it’s been exposed to temperatures above 5°C for more than four hours, bin it, no matter what it looks like.
Conclusion
A Brisbane blackout during storm season is not an unusual event -- it's a routine risk for most households in south-east Queensland. The practical response is straightforward: keep the doors closed, note the time, act on the 2-hour and 4-hour rules for perishables, and check carefully for surge damage once power is restored.
If your fridge or freezer isn't cooling properly after a blackout, or if you're hearing unusual noises from the compressor, that's a job for a qualified technician.
