Thanks all for the replies. I didn't realise this would prove to be such an emotive topic!
We're renting in campbelltown and the rental agency seems to think that the property has adsl and cable -
I realise the options may not be as extensive as the UK but we do need Internet in the property ASAP for work reasons hence my online research prior to our move. I've had a look at the tpg site and according to their coverage maps, the adsl2 exchange isn't too far and it looks like our street has adsl 2 coverage. May go with tpg as they include uk calls which would be great. For those on tpg, can I ask how long it took to set up and what has your experience been so far?
Thanks soo_the_panda for the info re amaysim. I saw the info re it online but was a little unsure as hasn't heard of amaysim - have you had any problems with dropped calls/reception?
