This page provides information about changes to the system that underlies Australia’s location information.
On the 15th of December 2017 Geoscience Australia and
the Intergovernmental Committee on Surveying and Mapping (ICSM) officially
launched the GDA2020 datum, making it available to replace GDA94.
GDA2020 is the first in a series of new datums, reference frames, working surfaces and models that are being provided to support Australia's positioning and mapping requirements in the 21st century.
Moving from GDA94 to GDA2020 in Tasmania
Changing from using GDA94 to GDA2020 coordinates on spatial datasets is being implemented individually in each jurisdiction with national coordination promoted by ANZLIC and facilitated by ICSM.
In March 2020 Land Tasmania released an implementation policy which describes how Land Tasmania intends to manage GDA94, GDA2020 and web mapping during the first stage of datum modernisation.
