[QUOTE="Phil8303, post: 640842, member: 21490"] For what it's worth, I know that 1994 was when a heap of the WA maps changed. Anything before 1994 was probably not WGS84, and to convert the old 1966 (called officially the AGD66) system to WGS84 you have to add 140 metres to each of your easting and northing coordinates.
