We are with Tpg on adsl 1. It very rarely drops out.From our research you can only get adsl 2 with telstra. Last time we looked Vivid didnt have wireless in this area. Not sure about vodafone. Mobile phone recption isnt good so the wireless internet may not work very well either.
I havent heard anything about not being about to get an adsl line. We had no trouble getting one.
