Selected transformation

Method: NTv2

Grid Files: National 84 (02.07.01).gsb

Remarks: Parameter values from AGD84 to GDA94 (5) (code 1804). Approximation assuming WGS 84 is equivalent to GDA94; ignores the low accuracy of the WGS 84 ensemble and the inconsistent application of tectonic plate motion to WGS 84 data.
