Address confidence

2014 marks the first decade of Australia's Geocoded National Address File (G-NAF) - a time during which this new benchmark for geocoded address accuracy has become widely accepted.

In March 2004 a selection of politicians and geospatial industry stakeholders assembled at Parliament House in Canberra to mark the birth of something new – a Geocoded National Address File for Australia, or G-NAF. The processing methodology underpinning the G-NAF dataset was a world-leading technology capable of building a quality assured national address index from ten diverse data sources. In 2014, PSMA Australia is celebrating the 10th birthday of G-NAF. Within this brief ten years, PSMA’s G-NAF has evolved from an unknown quantity utilised only by its patrons, the Australian Bureau of Statistics (ABS), the Australian Electoral Commission (AEC) and Australia Post; into a dataset utilised throughout the economy. Across government and industry, authoritative address data from G-NAF supports many policy and business systems providing important services to Australians - including emergency response, social services, insurance, telecommunications and navigation. In the 2013 strategy paper Advancing Australia as a Digital Economy, the Australian Government announced its intention to explore options for providing open access to G-NAF - making it freely available to all Australians. This was recognition of G-NAF’s fundamental place within the Australian digital economy and a sign of the growing acknowledgement that some flavours of national geospatial data are an essential digital infrastructure – an invisible and virtual parallel to our physical infrastructures such as the roads we drive on and the utilities that provide us with essential services.
