Warn, inform and advise people

Control Measure Knowledge

Under the Civil Contingencies Act, Category 1 responders are required to put arrangements in place to make information available to the public about civil protection matters and to maintain arrangements to warn, inform and advise the public in the event of an emergency.

In some situations, information provided to the public may have to be restricted, especially if its release could cause panic and potentially result in further harm to people.

Information communicated to, or withheld from, people can influence their behaviour. Communicating with people, particularly those in groups or crowds, is essential to maintain order and manage behaviour.

In emergencies, the key communications objective will be to deliver accurate, clear and timely warnings, information and advice to people, so they feel confident, safe and well-informed.

Warnings, information and advice should:

Be specific and clear

Be timely and accurate

Come from a credible source and be verifiable

Convey the nature and extent of the danger

Warnings, information and advice can be delivered in many ways including:


Visiting premises – residential and commercial

Media and social media announcements

Public announcements in areas such as public buildings, shopping centres, sports venues and transport networks

Strategic Actions

Tactical Actions
