Transform Coordinates

Remarks

Derived at 327 stations. May be taken as approximate transformation AGD84 to WGS 84 - see code 15789. For higher accuracy use AGD84 to GDA94 (2) (code 1280). Note: AGD84 officially adopted only in Queensland, South Australia and Western Australia.

Frequently Asked Questions

How do I convert AGD84 to GDA94 coordinates?
