ANZLIC Announcement on GDA2020 Adoption Date

18 Mar 2019

30 June 2020 is the date by which ANZLIC member agencies in Australian states and territories will be ready to deliver and receive foundation spatial data on the GDA2020 datum.

This date applies to foundation spatial datasets managed by ANZLIC and the Intergovernmental Committee on Surveying and Mapping (ICSM) member agencies in Australia.

The setting of a date will provide greater certainty to users of foundation spatial data about when data will be available in the new datum. The date also provides a focus for implementation teams within each jurisdiction to assist central government agencies, local government, utility and industry sectors to work with the new datum.

Individual agencies may make foundation spatial datasets available on the new datum earlier than 30 June 2020, subject to internal system upgrades and the readiness of software to handle the new datum. To make transition less disruptive, any dataset or service made available on GDA2020 will continue to be made available on its original datum.

ICSM and ANZLIC welcome engagement from the user community on all aspects of the datum modernisation project. ICSM will keep the user community informed of implementation progress via the ICSM website at, at major spatial forums throughout 2019, and through ICSM and ANZLIC social media channels.

The move by ANZLIC member agencies to offering foundation spatial data on a new datum will support applications that rely on accurate satellite positioning such as in-vehicle navigation, automated mining operations, precision agriculture and surveying.

More information on the datum transformation, and products to help transform individual datasets, is available on the ICSM website at Alternatively, ICSM can be contacted at major spatial events in 2019, through the online forum or via email at
