G-NAF is a database of all the physical addresses in Australia. Because there is no single organisation that is responsible for assigning and collating addresses in Australia, G-NAF is built from addresses supplied by ten contributors including the land agencies in each state and territory of Australia. As each contributor collects and stores addresses differently, the G-NAF production process involves independently examining and validating every candidate address, then textual and spatial matching. Addresses from different sources found to be identical are merged into a single G-NAF record with feature level metadata capturing its linage and quality. Through this process over 30 million contributed addresses are distilled into over 13.5 million G-NAF addresses.
