The federal government plans to display a new alert at sports matches and other events telling people what to do in response to a terrorist attack.
The message "Escape. Hide. Tell." has been inspired by a similar public education initiative in the UK.
"The Escape. Hide. Tell. message informs the community and businesses about what to do in the unlikely event of a terrorist attack or another similar attack," the Home Affairs Department told The Herald-Sun on Friday.
"The advice is particularly important in an attack using firearms, knives or other weapons."
The UK message is "Run. Hide. Tell." while in the US it's "Run. Hide. Fight".
