Maybe some clarification is need here.
Because the Aurora platform is encrypted it cannot be classed as FTA. It has been (wrongly) put in the FTA catergory because of the channels offered on it (ABC SBS Imarja, etc.) but it is still not FTA.
True FTA is when received signals can be viewed on a satellite receiver without having to decrypt them.
Pay a visit to Lyngsat -
http://www.lyngsat.com/asia.shtml and have a look at the following satellites:
Intelsat701, PAS2, PAS8, OptusB1, OptusB3, PalapaC2, Asiasat3S, Asiasat2, Insat2E and Thaicom3.
They are the main satellites viewable from Australia - when you look through the transponder list for each sat you will see channels marked in yellow - they are the FTA channels and are viewable with a standard digital receiver such as the Humax, eMtech, Topfield models (but not Pay boxes), without the use of a card or subscription.
Looking at the page for each of the satellites listed above (except OptusB1 and OptusB3) the first block of transponsers listed are the C-Band channels (3700 - 3000) and the motorised $2k system I described above would receive most of them (depending on where you are).
The lower block of listed transponders are the Ku-Band channels (10500(?) - 12750) and require a differant dish system - whether you use seperate dishes, a motorised system or a Toroidal unit depends on what satellite(s) you wish to receive.
To receive Aurora you need a Ku-Band dish pointed at OptusB3 (same sat as PayTV), a receiver capable of decrypting Irdeto1 signals (Humax5410z, etc) and an Aurora smartcard. You can get an Aurora card from a number of satellite dealers and have it enabled (by ringing the supplied Optus activation number) to view ABC, SBS, a few other odd TV channels and some radio channels, BUT, you cannot get enabled any commercial channels unless you can prove that you are in area which receives little, or no, commercial TV signals - a report by a reputable antenna technician is required and has to be submitted to Optus for approval by both themselves and the channel(s) you wish to enable.
So the question is do you wish to get the real FTA stuff or the Aurora package?
