-Combining these with the known values of the ellipsoid parameters of the ANS, a custom CRS can be defined in PROJ to allow transform between ​ANS and GDA94 coordinates. This can then be used in QGIS to '​reproject' ​ANS georeferenced rasters into a GDA94 CRS.+Combining these with the known values of the ellipsoid parameters of the ANS, a custom CRS can be defined in PROJ to allow transform between ​ANG and GDA94 coordinates.
