Sorry, no, that was a mistyping on my part. I meant GB.

Here's the Internode plans: http://www.internode.on.net/residential/adsl_broadband/easy_... (I actually don't have one of those plans, but you can see the 30GB for 39.95 unbundled).

And I suspect this is the plan the OP was referring to: http://go.bigpond.com/broadband/9-plan/ (Unbundled it's $39.95 for 2GB)

Telstra Bigpond used to sell the same plan with no bundling discount. It wouldn't surprise me if some people are still on it.

AFAIK no one in Australia caps on speed, except in special circumstances. You get ADSL as fast as it can go up to your data cap, and then it slows.
