The party's Digital Rights spokesperson Senator Jordon Steele-John made the call during question time on Wednesday, saying the deal on the Telecommunications (Assistance and Access) Bill 2018 had been made in the "secretive and exclusive" Parliamentary Joint Committee for Intelligence and Security.
The last time the Greens spoke out on the bill was on 11 September. The bill is due to be presented for a vote in Parliament today, after the PJCIS recommended it be passed once it was amended according to the panel's recommendations.
Steele-John said: "This anti-encryption legislation has been condemned by the United Nations, the Human Rights Commission, the digital rights community and Australia's tech sector at large. It is a threat to the online safety, security and privacy of every single Australian.
"Technology and innovation companies will leave Australia in droves as it becomes clear these laws are incompatible with the European Union's General Data Protection Regulations.
"Furthermore, any individual — whether that be a politician or a journalist — who uses encrypted messaging services to ensure the privacy of their sources, or the privilege of their policy discussions, should feel threatened by this bill's potential unintended consequences.
"What was intended to be a national security measure will in fact become a national security threat, as hackers and third parties exploit the necessary weaknesses built into end-to-end encryption services. For them, Christmas will have come early in Australia.
"This is massive government overreach and something we should all be extremely concerned about. It makes a mockery of our right to privacy, leaves us more vulnerable to cyber espionage and permanently weakens existing protections we all rely on to stay safe and secure online.”
