@msolga,
Er...well, I have (ADSL2 (broadband fast enough to stream video and such ) for $39 a month ( I think) from chariot.net.au
I get 2 Gigabytes a month dor that...after that I am on dial-up speed unless I pay more.
Haven't had to do that...and I have downloaded 2 entire TV series (Breaking Bad) ...though they are short seasons.
Chariot's service is rude and off-shore, and I have trouble understanding them sometimes.
I am not sure if this was a special price for existing slower broadband customers? I'd check.
A friend has just switched to Internode and is VERY happy....I am not sure what she is paying.
There was argy-bargy with Telstra re phone access and such, because Telstra are so horrible (I don't get why...I had no issues.)
My personal experience with Optus is that their service is very poor...but that is re mobile phones.
I have heard people praise Virgin.
Edit.
You wanna combine phone...didn't see that.
I don't think chariot and internode do phones, sorry.
