We are with netspace which has just been taken over by iinet. We have been with Telstra and Optus and tpg in the past. We are very happy with netspace. We pay $69 per month for phone and bb. If we go over 10gig + 10 gig, then it's shaped so no scary bills. We have never even been close to getting shaped!
If we email them they call back or email back, and we have yet to have any real issues with them.
Have you had a sneak peak at the NBN website to see when your new suburb is going to get hooked up. We have to wait 12 month to 3 years.
