How it works

NoticeRadius turns an address and a distance into the list of every letterbox you need to reach. Here is exactly what it does, and what it does not do.

Finding the site

Start typing the job address in the search box. Suggestions come from G-NAF itself, so there is no third party geocoder guessing at it. Pick the match and the map centres on that exact address point.

If the site has no street address, a paddock, a showground, a stretch of road, skip the search and tap the map where the work is happening. You can drag the pin afterwards to fine tune it.

Choosing the radius

The five presets cover most jobs. The slider and the metre box handle everything else, up to five kilometres.

RadiusTypical useRough count in a suburb
100 mSmall works, a single crane lift, a driveway pour30 to 60
250 mOut of hours trades, a street closure150 to 250
500 mA fireworks display, a water shutdown500 to 900
1 kmLarge display, major works, suburb farming2,000 to 3,500
2 kmBig events, wide campaigns8,000 plus

The count updates as you change the radius, so you can see the cost of going wider before you commit to it.

What you get

The address list

A CSV you can open in any spreadsheet. One row per letterbox, with the street address, suburb, state, postcode, the distance from your pin, the coordinates, and the G-NAF identifier so the entry can be traced back to the government dataset.

The labels

A print ready PDF laid out for Avery L7160 and J8160, twenty one labels to an A4 sheet. The addressee line defaults to THE RESIDENT and you can change it to anything you like under Fine tuning.

The job summary

One click copies the address, radius, letterbox count and date to your clipboard. Useful for pasting into a quote, a works notice, or the file you keep in case anyone asks later.

Fine tuning the list

  • Include units and apartments. On by default. Every unit in a block has its own letterbox, so leaving this on is usually right. Turn it off if you are only doing street level delivery.
  • Primary addresses only. Drops sub addresses that sit under a parent property. Useful for large sites where you want one notice to the property rather than one to every tenancy.
  • Exclude vacant land. On by default. Removes lot only entries with no street number, which are usually undeveloped blocks with nothing to deliver to.

The honest limitations

G-NAF records physical address points, not postal delivery points. Most have a letterbox. Some do not, and a handful of letterboxes exist that G-NAF has not caught up with yet, usually in brand new estates, because the dataset refreshes quarterly.

That is fine for a walk, where the person delivering can see which properties have a letterbox. It is not good enough on its own for posted mail. If you plan to put these through Australia Post rather than deliver by hand, the G-NAF licence requires you to verify each address against a second source first.

Does it cover the whole country?

Yes. All 16,091,511 addresses across every state and territory, from the August 2026 G-NAF release.

Do I need an account?

No. There is nothing to sign up for and nothing to pay.

How current is the data?

G-NAF is published quarterly by Geoscape on behalf of the Australian Government. We load each release when it comes out. A house finished last month may not be in it yet.

Can I get owner or occupier names?

No, and deliberately so. This is address data only. There are no names, no phone numbers and no personal information anywhere in the system.

Why does the count change when I move the pin a few metres?

Because the circle is measured from the pin, not from the property boundary. A few metres either way can bring a whole side of a street in or out. Put the pin where the activity actually is.

Put in an address you know and see what comes back.
