Finally know exactly
why you're at risk —not just that you are.
Every other emergency app tells you there's a fire nearby. AlertAU tells you why that fire is dangerous to you specifically — your distance, the wind direction, your evacuation route — in plain English, right now.
Every other app tells you there's an emergency.
We tell you why it affects you.
Generic alerts cause panic and confusion. Location-specific, reason-based alerts cause action. That's the entire idea.
The same fire. Three different people.
Three different WHY messages.
Because the fire doesn't affect everyone equally — and your alert shouldn't pretend it does.
How we calculate your risk
Four layers working together — from raw satellite data to a plain-English explanation on your phone in under 30 seconds.
Live Data Ingestion
NASA FIRMS satellite fire hotspots, Bureau of Meteorology severe weather feeds — pulled automatically every 5 minutes, 24 hours a day.
Your-Location Risk Score
Every incident is scored against your GPS coordinates — not a suburb or postcode. Wind direction, proximity, fire spread rate, flood zone, and your exact distance all factor in.
The WHY Engine
This is the core. GPT-4o takes the localised risk data and generates a specific, personal explanation of why your address is affected and what the threat timeline is.
Personalised Push Alert
Notifications include the WHY, not just the what. Only alerts relevant to your location reach you — so you're never overwhelmed, and you always know it's real.
NASA FIRMS
VIIRS satellite thermal hotspot detection — updated every 3 hours globally. Provides fire location, intensity, and spread direction used to calculate your personal risk.
Free APIBureau of Meteorology
Official Australian severe weather warnings, flood watches, heatwave alerts, and storm forecasts — used to calculate wind direction relative to your address.
Open DataGDACS + Copernicus
Global disaster alerting and EU satellite emergency mapping — enabling expansion to Europe with the same personalised WHY architecture already built.
EU ReadyClick any incident. See exactly why it affects you.
Notice the red "Why you are at risk" box on every incident — your distance, the wind direction, your flood zone. This is what makes AlertAU different from every other app.
The WHY — right on your lock screen.
When a life-threatening emergency is approaching your home, you shouldn't have to open an app to understand it. The reason you're at risk is in the notification itself.
The WHY is in the notification
Wind direction, your distance, estimated threat time — right on the locked screen. Not just "fire nearby."
Your location is the centre
The map is built around you. Every marker shows your distance from the incident, not a generic regional label.
WHY visible in every card
Each incident shows the specific reason it's relevant to your location — at a glance, before you even tap.
Full WHY + plain-English brief
Tap any incident for your complete personalised risk explanation and step-by-step safety instructions in plain English.
Plain English, always
No fire behaviour indices. No jargon. Just "the wind is blowing toward your house and here's what you need to do right now."
Nearest resource, every time
Not just "go to a shelter." Your nearest cooling centre, evacuation route, SES office — calculated from your exact GPS location.
Only alerts that matter to you
No broadcast spam. If a fire is 400km away with no wind toward you, you won't hear about it. Your phone is only interrupted when it genuinely matters.
The people who need this most are often the hardest to reach.
Elderly Australians, CALD communities, and people with disabilities are disproportionately affected by emergencies — and disproportionately underserved by existing alert systems.
Designed for elderly users
Large text, plain English, high contrast, and single-tap actions. The "why" explanation is written to be understood by someone under stress, at any age. No technical knowledge required.
Multilingual — instantly
The AI safety brief can be generated in any language in seconds. CALD communities who don't receive emergency alerts in their first language are often the most vulnerable — this closes that gap.
Accessible by design
Screen reader support, keyboard navigation, WCAG AA contrast ratios, and reduced-motion options. Accessibility is baked in from the start — not patched on at the end.
