This is very disturbing but not surprising. The UK has become a real police state and Australia isn't far behind.
These sorts of laws are complete overkill and destroy the human rights of everybody.

Israel, which has a much more serious terrorist threat than the UK and has done a much better job at preventing terror, does not have these sorts of laws.

Ipso facto they are not necessary to be serious about stopping terrorism and are used by stupid and lazy legislators to substitute for the hard work of getting inside terrorist networks.
