G'day Paul,
I researched these repeaters ( boosters are illegal ) a couple of years ago with the view to use in the caravan mostly for data.
My understanding is that the main unit that is in the market is ACMA approved for the three Australia mobile phone carriers of Telstra, Optus and Vodaphone.
To my knowledge, there are no other carriers, just resellers.
So any unit that has ACMA approval for the mentioned carriers would be legal.
2 reasons I did not purchase were cost and no assurance of exclusive use.
For the later, it was explained to me that if I were parked up in a caravan park with marginal signal strength and I were to switch on one of these repeaters, then all other mobile phone users within signal shot could ( would ) use the the available signal even though they would not know why their signal strength suddenly improved.
It was also explained to me that ( at the time ) there was no means to restrict access to specified mobiles.
It would be worth investigating this alone before you venture further.
Also worth checking if they cover 2G, 3G and the exclusive data 4G.
Steve
