Does GDA94 occur on a particular date?
There is no single date. However, most Western Australian government bodies changed during 2000. DME, DOLA and other WA government bodies will change between 4/12/2000 and 18/12/2000, and these are critical dates for operators in WA. The Commonwealth has not yet passed the necessary parallel legislation. Dealings with the Commonwealths where datum is specified in regulations, mainly deeper water offshore petroleum tenements, are expected to remain AGD-based until the middle of 2002.
