Dick,
WAM in Tassie is due to go online shortly and undergo initial testing. I believe that it will be compared against the radar data and then hopefully on to the operational platform before mid year. Of course like the ADS-B project, the number of site locations has been reduced as time has gone on. AsA are keen to get it up and running asap as the "portable" radar is an expensive asset which would be better used if made "portable" again...
