Available transformations
to EPSG:4283
EPSG:4283 - GDA94

Selected transformation

Method: NTv2

Grid Files: wa_0400.gsb

Remarks: Withdrawn and replaced by AGD84 to GDA94 (4) (code 1593) due to binary file format error. Input expects longitudes to be positive west; EPSG GeogCRS AGD84 (code 4203) and GDA94 (code 4283) have longitudes positive east.
