I'd answer "No".

1. A lot of these creepy proposals never get past the proposal stage. Take the Australia Card.

2. Australia's legal institutions have proved reasonably effective in dealing with such creepy laws. E.g. laws banning the Communist Party were struck down in the '50s.

3. This latest proposal is about law enforcement, not censorship. Creepy anti-terrorism laws aren't a peculiarly Australian vice.

4. The government doesn't have a majority in both houses; it needs the complicity of non-government members to make laws.

None of this is to say that this is a good thing. It's creepy and embarrasing and I wish they'd stop.
