Find Australian Postcodes Inside a Radius

Map of Australia where you can specify a point and a radius to search within and return all the post codes found inside that radius.

Radius Search Map


Step 1 : Radius km (maximum = 500km) OR miles (maximum = 310 miles)

Step 2 : Click on map OR Place radius by location name or post code :

Step 3 : Remove duplicate postcodes? :

Post Code,Suburbs,Distance()


Input a radius to search within in KM or miles. Click on the map or type in an address or Australian post code on the center of your search. After a delay, the results will appear in the text box. If there is a reasonable number of points, they will also be shown on the map. If you hover over a marker, you will see it's post code.

You can find a comma separated list of the post codes and suburbs in the large text box below the map.

There is a limit to the radius because excessive results can take a long time to load and some web browsers struggle to load them all.

Future Improvements

  • Display distance between centre point and marker when you hover of the marker

The way the data is presented is really nice. Better than some other tools available.

Hi Lyn, that's good to here! Thanks for the positive feedback!

I used 'List USA ZIP Codes Within a Drive Time Radius' in the blog to create a saved area based on a defined drive time. Then Aus postcodes within a defined area to extract the postcodes. Worked like a dream! Many thanks

Thanks for a solution, will try it and let you know how I go.

Hi Lyn, if you refer to List USA ZIP Codes Within a Drive Time Radius and swap ZIP codes for AUS postcodes, this should do the trick.

Hi 2281 should be sorted now
By Free Map Tools on 18th October 2017

Great tool thanks!! Note: Post Code 2281 is misplaced

I know this is probably out of scope but postcodes within a driving distance radius would be really useful.

Wonderful help. Thankyou.
By Don Edwards on 25th September 2017

Great help thankyou.

Booyah. This tool things your tool is the business. Great work. BTW, can anyone explain the relevance of an AU postcode? Back in the UK, you can address a letter with only the postcode and it will almost always get to the recipient as a UK postcode narrows an address down to a few properties. An AU postcode narrows an address down to a few thousand. Almost as pointless as the accolade of making the Australian AFL team! Booyah

Hi Bill, sorry, we don't understand. In what context do you see these two terms?
By Free Map Tools on 3rd August 2017

Is it possible to define urban v rural? would save a lot of time thanks

Ditto Vicki

Hi, have been getting the same error message as Vicki for a couple of weeks now. When I open the console I get a "You have exceeded your daily request quota for this API" message, but since this is the first time I have opened up this site this week I don't think that's the problem (well at least not on my end).
By Nicole on 17th July 2017

Sorry! Something went wrong. This page didn't load Google Maps correctly. See the JavaScript console for technical details. These words are showing in the radius search map box...can you help
By vicki on 10th July 2017

The combined output is now sorted by distance from centre of the radius.
