John, ADS-B is not used in the States currently on 1090 Mhz ( Transponder TX frequency ) They do however have mode S replies which depending on what downlink is used , or DF reply, contains some basic information which they are decoding and displaying. This same receiver can be used here in Oz , all it needs is proper decoding of the full DF17 and 18 replies and an understanding of the ADS-B messaging. We have a receiver here that does that, eventually most will have these in their cockpits coupled to a moving map or PDA to display ADS-B in Australia, providing excellent situation awareness of other traffic that is ADS-B equipped, I hope to be displaying this at the SAAA convention at Wagga in October, all are welcome for a hands on demo of ADS-B and possibly the new Filser SX1000 glide computer which will also be capable of displaying ADS-B aircraft.
For everyone's interest, Airservices will be releasing their tender for supply of 1500 ADS-B transmitters this month, these will go into selected 1500 Australian registered aircraft for free, I am not sure how the selected aircraft are selected. Already quite a few international jets are ADS-B equipped , as well as virgin and the 17 or so in the Bundaberg trial. I have already supplied transponders here which can be software upgraded to ADS-B when they want to ( see www.avionicsaustralasia.com ) which are going into RV7's so the transition is happening. The decision for a lower airspace go / no go for ADS-B is still scheduled for next year, so the lower airspace is still not a done deal, but there must be some confidence there otherwise we wouldn't be seeing a tender this large.

I can't see how this gadjet would work otherwise, and there is no mention in the "blurb" that ADSB needs to be implemented. Regarding cost of base stations, I guess the ones Airservices are buying cost a lot more than USD900, but then they are looking for high reliability, and wide environmental survivability plus remote control and monitoring of the station, which adds some complexity. Still cost *way* less and have much lower maintenance costs than a secondary radar installation.
