The legislation contains a number of amendments, including new powers for police to enter a premises without a warrant in emergency circumstances; expanding the 'urging violence' offence and extending the expiration period of regulations proscribing a terrorist organisation.

"The National Security Legislation Amendment Bill 2010 seeks to achieve an appropriate balance between the Government's responsibility to protect Australia, its people and its interests and instilling confidence that our national security and counter-terrorism laws will be exercised in a just and accountable way," said Attorney-General Robert McClelland.

"These measures are designed to give the Australian community confidence that our law enforcement and security agencies have the tools they need to fight terrorism, while ensuring the laws and powers are balanced by appropriate safeguards and are accountable in their operation."
