is there a way to import a KML file instead of manually defining the outline of the area

This is unbelievably good. Thank you!

Gaetan, sorry that's not possible.

Hello Everyone, Is there a way to do the opposite? By that I mean typing a list of suburbs and having the map that draws the point according to the suburbs I typed?
By Gaetan Chapon on 25th April 2022

Brilliant. If users haven't discovered the obscure User Menu at the top. It allows you to save your defined map areas, export, then come back later and adjust the boundaries if needed. Icing-on-the-cake!!

Great website. I own a small courier company and this site made it extremly simple too work out my pricing for the post codes in the zones I was able to create Just Brilliant

Awesome!!! What I have been looking for and more. Would be great to do a save image option.

Hi Tony, returning the postcode is the main purpose of this page. Subsequent to that we try to list associated suburbs to the postcode. For that reason, this tool should not be considered a way to obtain suburbs in the area. The accuracy of the suburbs listed is not perfect.

Hello Great Site. I notice if I draw an area close around Example Goulburn it grabs every suburb with the 2580 postcode. Is there a way to just select the suburbs within my drawn radius? Cheers

How can I download all Australian Postcodes with Latitude and Longitude in a CSV file. Like the options you have for the UK Postal Codes?

i was wanting to find a map of postcode's 2019 & 2035 . i failed could not figure how to do it !

Hi, can i have source code of get-australian-postcodes-inside-polygon.php ? I'm learning about finding zipcode in polygon area. Thank you so much!
By Son on 2nd July 2019

When I included Groote Eylandt in the defined area it omitted any post codes on the island. This caused issues and inconvenience and ended up wasting time. Could you please ensure that all post codes selected are generated including on islands. It would be much appreciated. Thanks

BM, we cannot change back. We cannot afford to on this free-to-use site. An update has been made to allow the polygon to be edited.
By Free Map Tools on 15th January 2019

Should not have changed this tool, we can cannot drag the point markers into position when zoning your desired area, makes things very difficult, please change back.
By BM on 14th January 2019

Hi Miguel, thanks for the suggestion - this is an interesting one! We will look in to feasibility
By Free Map Tools on 31st October 2018

This is amazing. What about a reverse function - you add in a set of postcodes, and then it'll highlight (or drop a pin) in each area?
