Free the G-NAF Address Dataset

"G-NAF is the authoritative index of geocoded Australian addresses. This award-winning dataset contains more than 13 million physical addresses that are sourced from the address custodians from each state and territory, the Australian Electoral Commission and Australia Post."

Compiled and maintained using data from a wide range Government agencies, it's only available at a cost, which means address geo-coding, a basic location service isn't freely available to foster innovation.

    Why limit it to the G-NAF? PSMA also hold other authoritive datasets that should be more freely available (such as transportation)

    Do they sell data collected using tax payers money?

    >> PSMA Australia Limited is a company owned by state, territory and Australian governments.

    Another awesome business idea created by politicians.

      The problem with opening the PSMA datasets is that the Australian government supplies very little of the content, hence it has limited influence over the PSMA right now. It's mostly aggregated state government data, and the states don't want to fund the PSMA as a national duty, they want a return for their data.

      The Office of Spatial Policy is on the record as wanting to make G-NAF free for all users by getting the Federal Govt to fund the PSMA themselves, but I don't know what the mood is in Canberra for this since the change of Govt.

    Hello All, thank you for continued interest in this dataset. We've received the following response from Office of Spatial Policy.


    The G-NAF, DCDB Cadastre, postcode and postal address datasets are all part of the ANZLIC – The Spatial Information Council’s multi-jurisdictional program the Foundation Spatial Data Framework. Under the Framework it is the goal of the Council to deliver these and other foundational spatial datasets as open and at no- or as low-cost as possible to the end user. The initial phase of the framework will be completed by April 2014, which will identify and deliver the datasets under the ten foundation themes in their current format. The second phase, seeks to work with all stakeholders to evolve the datasets to meet the stated goals of open and at no- or as low-cost as possible in addition to increasing quality and accessibility. Due to the considerable costs incurred throughout the supply chain for the requested datasets, especially for the G-NAF, the process of delivering these will be ongoing and a specific date cannot be provided at this point.


    Kind Regards,

      Hi Allan,

      Thanks for your comments on this. Since your message, have there been any updates to the status of the Framework with regard to G-NAF, etc.?

    While freeing the GNAF dataset entirely may be a non trivial exercise, it would be extremely interesting to look at the tools & processes used to create and work with the resulting dataset.

    I know through work for example, we take an improved version of the GNAF and perform a number of tasks to make it searchable. The efforts in loading it are non trivial, and the delivery mechanism is heavily manual.

    I imagine we are not alone in this, and the only things stopping us from publishing our home made tool chain (a few helpful ruby rake tasks to load into postgres) or metadata on github is the lack of demand; and the idea that our version of the GNAF payload may be different to other deliverables.

    Also, as a property valuation company we regularly deal with new property and physically survey sites. If we had an open API to allow us to contribute back changes (property X is being subdivided/is inaccurate/is related to parcels X, Y, Z ), we would absolutely do so - it would benefit us, other consumers of GNAF/Cadlite; and probably encourage other contributors - a net win.

    There is now some data here: ('PSMA Administrative Boundaries').

    They claim an 'open license' but The PMSA's full terms and conditions show it's nothing of the sort. It makes it impossible to use for any commercial purpose, even tangential such as income from click-through advertising or even just "brand recognition" according to the fact sheet. In fact, reading the conditions, I'm not even sure any non-profit would even want to go near it.

    Set up for a fail perhaps, or just the usual PHB madness?
