(null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Parameter values from AGD66 to GDA94 (12) (code 15979). Assumes WGS 84 is equivalent to GDA94; ignores low accuracy of ensemble and tectonic plate motion. Use only offshore: onshore CTs 1665-68 for ACT, NSW/Vic, Tas and NT respectively are more accurate.
