  • Australia including Lord Howe Island, Macquarie Island, Ashmore and Cartier Islands, Christmas Island, Cocos (Keeling) Islands, Norfolk Island. All onshore and offshore. , accuracy 3.0 m, code 8450 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Approximation at the 3m level assuming WGS 84 is equivalent to GDA2020. Ignores the low accuracy of the WGS 84 ensemble and the inconsistent application of tectonic plate motion to WGS 84 data.
