The Standard Emergency Warning Signal (SEWS) is a distinctive siren sound that is played over the radio, television and/or public address systems in areas such as shopping centres or sports grounds to alert the public that an official emergency announcement is about to be made concerning an actual or potential emergency that may affect them. The SEWS can only be authorised by Police and Emergency Services, in accordance with arrangements in the Emergency Management Manual Victoria.
Emergency Alert is a telephone warning system that emergency services can use to send alerts to communities via landline telephones based on the location of the handset, and to mobile phones based on the billing address.
In an emergency, you may receive a voice message on your landline telephone or a text message on your mobile phone. If you receive an Emergency Alert and want more information, follow the instructions provided in the message.
Emergency Alert is a community warning system that attempts to provide a message to the vast majority of phones in an area defined by the emergency services agencies. You should not rely solely on receiving a telephone warning as it is generally only used for life-threatening emergencies.
