The term 'lockdown' can be defined as an emergency course of action taken by an agent of authority, such as police or prison personnel, to contain a problem or incident within the area of its origin by controlling the movement of people.

In December 2005 the New South Wales Police Service initiated a 'lockdown' of the Sutherland Shire and other beach areas of New South Wales to contain race rioting (and retaliative strikes).
The New South Wales Labor government, in an emergency sitting of parliament, passed an array of amendments to legislation giving the New South Wales Police Service additional powers to 'lockdown' targeted areas and roads within New South Wales. The legislation introduced to deal with the Cronulla riots was the Law Enforcement Legislation Amendment (Public Safety) Act 2005 (NSW).
The Law Enforcement Legislation Amendment (Public Safety) Act 2005 (NSW) amended four separate pieces of legislation:
- Law Enforcement (Powers and Responsibilities) Act 2002 (NSW)
- Crimes Act 1900 (NSW)
- Bail Act 1978 (NSW)
- Criminal Procedure Act 1986 (NSW).
Under their new powers, the New South Wales Police Service 'locked down' targeted areas and roads at Cronulla, Bondi, Coogee, Maroubra and Brighton-le-Sands to prevent persons of middle eastern appearance from committing reprisal attacks and prevent white supremacist agitators from further violence.
