I think wholesale ADSL and ADSL2+ ports are a) only available when purchased in bulk, and b) still need a backbone provider and other network links and hardware in order to actually get access to the internet.
So form a co-op with other like minded in here.
ISP-level filtering is a bad idea, and a problem. Scrap the flawed idea, and the problem goes away.
It isn't ever going to go away. It's going to keep coming back over and over again until it is in, and not only in Oz, but a whole load of other countries as well.
Even Obama wants to do it to the USofA.
So like I said, time folk started thinking outside the filter.
