I found this:
Maps and the GDA, http://www.icsm.gov.au/gda/mapsgda.pdf

+---------------------------------------------------
| This map was produced on the Geocentric Datum of Australia 1994 (GDA94).
| Heights are referenced to the Australia Height Datum (AHD).
| For most practical purposes GDA94 coordinates and satellite derived (GPS)

Should we add WGS84 as short-cut in the datum table?
