This module creates entities for Australian postcodes.
It does this by importing from a csv file that is included in the module.
The information that it includes for each postcode is:
Postcode
Suburb
State
Delivery centre
Delivery centre type
Latitude
Longitude

As the module leverages the Entity API, it has views support for all fields.
There is currently 1 custom views filter for state (select options instead of an autocomplete).

NOTE: The included csv file is quite old (2011 I think, back when it was free). A more recent version can be purchased from http://auspost.com.au/business-solutions/postcode-data.html though I have not seen the format of the newer version so can not be sure it is in the same format.

Requirements:
Entity API

Australian postcodes
