Australian Postcodes - Search by Distance

Hi there,

I used to use the Dolphin software, and a few years ago, I purchased a module from someone that allowed searching by distance from a postcodes with Australia.

I am now using a different dating software platform, but am looking for a database to do the same thing.  Does anyone have anything?  I will then need to see if it can be integrated to the new software I am using (SKADATE).

Thanks in advance.

Thanks - but it is only for use with Dolphin apparently. 

Does anyone else have a database of Australian postcodes with longitudinal data that I can purchase?

Thanks and regards.
