Australia will be leading discussion on an encrypted technology crack down when ministers meet with Five Eyes nations to talk terror.
Attorney-General George Brandis and Immigration Minister Peter Dutton will sit down with their counterparts from the United Kingdom, Canada, New Zealand and the United States in Ottawa for two days.
Before leaving Senator Brandis noted the use of cyberspace by terrorists is an issue of critical concern to intelligence and law enforcement agencies around the world.
"Australia will lead the discussion of ways to address this issue; in particular the involvement of industry in thwarting the encryption of terrorist messaging," he said.
Prime Minister Malcolm Turnbull foreshadowed the meeting when he addressed the Liberal Party Federal Council over the weekend, insisting the internet cannot be an ungoverned space.
