Social media giants like Facebook and Google will face new laws to compel them to help Australian security agencies get access to encrypted messages from suspected terrorists and other criminals.

New law would force Facebook and Google to give police access to encrypted messages
The Australian government has proposed a new cybersecurity law to force global technology companies such as Facebook and Google to give law enforcement agencies access to encrypted messages sent by suspected extremists and criminals.

Malcolm Turnbull said on Friday the law would be modelled on Britain’s Investigatory Powers Act, passed in November, which gave intelligence agencies some of the most extensive surveillance powers in the western world.
