Australia's address ecosystem, led by Australia Post and supported by authoritative datasets like G-NAF, ensures accurate geolocation and delivery across vast urban and remote regions. It's a critical enabler for logistics, government services, and data-driven business operations.

Standard address format

A simple business address might look like the below example.

"address": {
    "address_line_1": "Experian",       // Lines 1-3 contain flexible delivery information
    "address_line_2": "1 Main St",      // like organization, street, PO Box, etc
    "address_line_3": "",
    "locality": "HOBART",               // Suburb or town
    "region": "TAS",                    // State abbreviation
    "postal_code": "7000",              // Postal code
    "country": "AUSTRALIA"              // Country
}

Address datasets

Australia Post's Postal Address File (PAF) is the official and authoritative source of postal addresses in Australia, maintained by Australia Post. It contains validated and standardized address data for all deliverable locations across the country, including residential, business, and PO Box addresses.

The dataset is updated regularly to reflect new developments, address changes, and removals, ensuring high accuracy for mail delivery and customer data management.

The Australian dataset is essential for organizations that rely on accurate address data for logistics, customer onboarding, and regulatory compliance. Industries such as e-commerce, financial services, utilities, and government use it to reduce failed deliveries, improve customer experience, and support operational efficiency. Its reliability and national coverage make it a cornerstone for address validation and data quality in Australia.

Include au-address in the datasets array within your /Search, /Validate or /Lookup request. See an example of a partial /Search request and response structure below.

G-NAF is Australia's national geocoded address index, maintained by Geoscape Australia. It consolidates validated address data from government sources across all states and territories into a single, deduplicated record for each unique address. G-NAF is widely recognized for its accuracy and consistency in representing physical address locations across the country.

The Australian DataFusion address dataset is a comprehensive and high-accuracy solution built on two authoritative sources: Australia Post's Postal Address File (PAF) and PSMA Australia's Geocoded National Address File (G-NAF). Together, these datasets provide validated, geocoded, and standardized address data for every state and territory in Australia. G-NAF includes contributions from state and territory governments, the Australian Electoral Commission, and Australia Post, offering a single, deduplicated record for each unique address.

Enrichment datasets

Regional Location Insights provide a robust foundation for location intelligence across Australia. It returns latitude and longitude for individual addresses. This enables precise geotagging of addresses, which is essential for applications like delivery optimization, customer location analysis, and spatial risk assessment.

Dataset identifier aus_regional_geocodes
Data source G-NAF: © PSMA Australia Limited: Spatial Data
Update frequency Quarterly

The Enrichment set includes a rich set of geospatial attributes such as mesh block codes, local government area identifiers, electoral boundaries, and statistical regions. It also provides multiple levels of geocode reliability and planimetric accuracy, allowing users to assess the precision of each coordinate.

The dataset supports hierarchical geocoding, offering address-level, street-level, locality-level, and highest-level coordinates, each with associated metadata describing reliability, elevation, and boundary extent.

Each Enrichment dataset is divided into one or more items. Experian Address Validation can be configured to return these items via the Enrichment section. Find detailed information about the available elements for the aus_regional_geocodes Enrichment set below.
