Geocoded National Address File is Australia’s authoritative, geocoded address file. This repo has a few tools / scripts to create derived datasets

Prerequisites

Working PostgreSQL instalation

Import data

• Create source directory

mkdir source

• Unzip FEB16_GNAF+EULA_PipeSeparatedValue_20160222170142.zip into source directory

• Import *.psv

./gnaf2pgsql | psql

• Merge state data and create flat table

psql -f g-naf.sql

Last step creates address_detail_flat table in public schema and staging schema has all merged tables and authority code tables

Address Flat Table

This table has all addreses (as in address_detail table) and contains addtional information. Appendix B in G-NAF documentation decribes G-NAF data model in detail.
