You’ve downloaded some fantastic data from, say, Data.gov.au and it is by post-code and you’d like to map to Federal Electorate. I’ve found two sources for this information:
- A download from the Australian Electoral Commission (AEC) website; and
- Table 2 – Postcodes by electoral division from the Australian Parliament House (APH) website.
I think the AEC is a more up-to-date resource as it takes into account any electoral boundary changes, however if it is unavailable (as it seems to be at the time of writing), you can fall back on the one from the APH source.
If you do use AEC data please note the licensing requirements (such as here).
