Tile locations for the prototype 32T array were surveyed sometime in 2008. The most definitive document available for the locations is "32T_Reordered_Tile_Corner_Coordinates.xls" in the Curtin J drive under .../MWA/Phase0-32T/Construction. It isn't known if this is truly the original, or derived from something else. This includes the location of the marker rock outside the MWA donga (these match exactly the numbers for the MWA centre above). The spreadsheet doesn't say who did the surveying or what the coordinate system was, but putting the easting and northing values into a Geoscience Australia Converter gives the exact public coordinates for the WGS84 and GRS80 ellipsoids, so it is reasonable to assume WGS84 was used.
