The main article is talking about blacklist filtering, not content inspection of any kind. There already was blacklist filtering and has been for years - when I signed up to the very awesome Internode (2007?), in their t's and c's there was a statement saying that there was a very small number of websites that they were forbidden by law to provide (route? resolve? can't recall), all from a government blacklist, and "you really wouldn't want to know what's on these websites"(ie: child porn). Internode is one of the good guys and Simon Hackett (owner) is huge on net neutrality - he will only restrict where the law demands it.

But honestly, moving overseas because of introduction of internet censorship? Why not campaign against it instead? Are there other things that disturb you here, or were you perhaps not being serious when you said you were 'seriously considering'?

If freedom of speech is what interests you, the RSF places Australia as having more freedom of speech than the UK, the US, and Canada. NZ and Ireland rate higher, so you may want to emigrate to one of those, but beware that the economies of both those places might make it tough to find a job.

If you're a polyglot, you've got a bit more choice: http://en.rsf.org/press-freedom-index-2010,1034.html

Or switch to Internode/iiNet ho oppose internet censorship aswell as being cheaper in some cases and support powerusers well (ipv6, adjusting your line's DSLAM profile for lower ping or higher reliability and letting you run servers on any port

If you route /all/ traffic on your computer through SSH, are there any downsides? Like, latency or some sites restricting you from accessing (Sounds silly, I know, as the idea is to have open access to all websites but I thought it may be a possibility), online multiplayer, etc?

Or would it be more reasonable to route only select data like HTTP, FTP and email? I s'pose any instant-messaging too..

Nah, Senator Fielding will only be in the Senate for a few more weeks. After him the Greens will hold the balance of power. Personally I think they're mostly loons, but they "get" the internet better than the major parties.
