 The National Security Hotline

Call the National Security Hotline on 1800 123 400 

The National Security Hotline (NSH) 1800 123 400 is a vital component of Australia’s national counter-terrorism efforts.

The NSH was established on 27 December 2002, and has since received more than 300,000 calls, faxes, letters and emails. A significant number of reports to the NSH have contributed to investigations or initiated new ones.

The nature of terrorism is changing, with callers providing information on the use of websites or social media platforms promoting violent extremist ideology, suspicious travel planning, and reports from people concerned that someone they know is becoming radicalised towards violent extremism.

Even if you think it’s probably nothing, the smallest piece of information can be valuable. If something doesn’t add up, speak up by calling the National Security Hotline on 1800 123 400.

If you are travelling overseas you can call the NSH on (+61) 1300 123 401.
