Frequently asked questions
How does it find my postcode?+
Your browser asks for permission to share your location. If you allow it, we compare your coordinates with the centre of every Australian postcode and show the closest one. Your location never leaves your device — the lookup happens in your browser.
Is it accurate?+
It returns the postcode whose centre is nearest to you, which is correct in most cases. Near postcode borders it can occasionally pick a neighbouring postcode; use the search to confirm.
It says location is unavailable — why?+
You may have declined the permission, or your browser/device has location turned off. You can still find your postcode by searching for your suburb.
