Data highlights

A short-cut to new datasets in

Did you know that you can view datasets that have been recently created and uploaded to Visit (note this will take some time to load) and click on the relevant tab from the menu on the left-hand side of the screen:

Openly available Geocoded National Address File (G-NAF) – tell us what you think!

The Spatial Data Policy, Public Data Branch of the Department of the Prime Minister and Cabinet is seeking feedback on the openly available Geocoded National Address File (the G-NAF) and ask that you please complete a short survey at:

The survey is being undertaken to build a more in-depth understanding of the innovation, efficiencies and productivity achieved through access to the open G-NAF.

Your feedback is important for informing the future directions of the open G-NAF initiative.

Feel free to forward this email on to other government, private, community or research sector entities as feedback from a wide range of entities is welcomed.

This survey is published and managed by the Public Data Branch of the Department of the Prime Minister and Cabinet. All information provided will be treated as confidential and will only be used as aggregated data to inform policy decisions unless you specifically agree for your organisation’s use of open G-NAF to be used as a case study.

Responses to this survey are due by 31 May 2017.

If you have any queries regarding the survey, please email

Background on the openly available G-NAF

  • On 26 February 2016, the Australian Government made PSMA’s Geocoded National Address File (G-NAF) openly available via with updates published quarterly.
  • The G-NAF is one of Australia’s most ubiquitous and powerful spatial data sets and is now available free of charge. The G-NAF contains more than 13 million records for each physical address in Australia. Making the G-NAF openly available has removed licence barriers and enabled greater use of the data and opportunities for innovation.
  • The G-NAF can be used for a wide range of business or operational purposes, such as infrastructure planning, business planning and analysis, logistics and service planning, emergency and disaster response, personal navigation and mapping, fraud prevention, address validation at the point of entry for business and government, and effective government service delivery and policy development.
  • In its first year of open release, the G-NAF was downloaded more than 2,700 times. By comparison it was only downloaded around 120 times a year when it was available under restricted licence as a proprietary PSMA product.

Thank you in advance for your participation in the survey, your feedback is appreciated.

Basemap update

Landgate is developing a new WA basemap service for SLIP in consultation with other agencies. Access to this shared basemap will significantly reduce the time and effort invested by many organisations in creating and maintaining their own versions of basemaps.

The scheduling of the work package is now complete and technical development should be completed around August 2017.

For more information on the Landgate basemap, please contact and write Landgate basemap in the subject line.

This month we address a question related to data access.

When previewing some data resources in I get prompted for a user name and password. How do I access data that is not freely available to the public?

Access to some datasets in Data WA may be secured. For example, the datasets may be part of subscription services that involves a charge to access the data or be restricted to select pre-approved users only. Note, all data downloads require a registered SLIP account for the purposes of reporting usage for custodians.

If you have access to a Landgate subscription service enter your SLIP credentials (email address and password) when prompted to view or download the resource.  

For more information about accessing subscription services, please contact Landgate's Business Sales and Service Team, or +61 (0)8 9273 7683 (direct line) Monday to Friday, 8.30am to 5pm (AWST).

How will I know if data is not freely available?

Author and maintainer contact details are included under Additional Info in If you wish to access a data resource and you do not have permission, you can contact the data author to discuss access approvals. It may be necessary for you to put forward a business case for the data.

WA’s Open Data policy

The Western Australian state government collects and uses a vast array of data in the course of its everyday operations. This data is an important strategic asset and when managed well is a source of significant value to the state.

The purpose of the Western Australian Whole of Government Open Data policy is to improve management and use of the public sector’s data assets in order to deliver value and benefits for all Western Australians. This includes greater release of appropriate and high value data to the public in ways that are easily discoverable and usable.

Across Australia and the world, the approach to open data varies to some extent.

For the purpose of this policy, data is considered ‘open’ when it is:

  • released and available for the general public (not for exclusive use)
  • easily discoverable
  • in formats that are modifiable, non-proprietary and machine-readable
  • licensed to enable reuse and redistribution
  • available at no cost to users.

The policy recognises the above situation for ‘open’ data is not always possible or appropriate.

For example, there may be instances where more restrictive licenses are used and/or a charge is applied. Read the full Open Data policy.

If you have a question that you’d like answered, please contact and write SLIP services FAQ in the subject line.
