As part of a federal crackdown on "Internet-assisted crime," Australia's government plans to block access to websites used for organizing protest activities.

Internet regulator, the Australian Broadcasting Authority, only last week decided not to block access to websites organising protests for the World Trade Organisation meeting in Sydney.
