Hi Rob, Thanks for your reply. I can translate the 'spatial' data easily (FME). But we have an xy coordinate as attribute data to go into our SQL databases. I need to know if these coordinates change so I can update the attribute information. Funny you should mention David, I deal with him extensively (we contract to the CoM)

You can search the web for 'datumtran' or go to this site http://www.icsm.gov.au/icsm/gda/datumtran_download_register.php which I think is where we got it from. I know we downloaded it and installed it but I can't remember where we put the original zip file. Only problem we had with this software was that the screen resolution had to be changed to show the entire application startup box. Apart from that it works brilliantly. Only problem is that you have to do each coverage individually, no batch options are available as yet. If you have problems, maybe I can help. The NSW writers are also very helpful. Incidently, have you tried David Hassett or John Wardrop at City of Melbourne (John is on 9658-9345), they may have the other translating software which does allow batching or 'whole directory' translating. Even though they are an ESRI shop, I believe the software is not manufacturer specific, and MCC has hundreds of coverages to convert.

Its giving me a headache.... We've got heaps of point data with X, Y's associated with them and they need to be changed from AGD to GDA, I need to know if I have to do a coordinate extract as well as a reproject? I am 90% they do change but I would love some more expert opinions. Regards...
