The majority voted in favour of a motion "[t]hat the remaining stages of this bill be agreed to and this bill be now passed." Since the bill has already passed in the House of Representatives, it can now become law.
What is the bill's main idea?
According to the bills digest:
The Telecommunications and Other Legislation Amendment (Assistance and Access) Bill 2018 will amend a number of Acts—primarily the Telecommunications Act 1997, the Australian Security Intelligence Organisation Act 1979 and the Surveillance Devices Act 2004 (SD Act)—to facilitate access to certain communications and data for the purposes of disrupting and investigating criminal activity and threats to national security, including organised crime and terrorism.
The Government is responding to the impediment that the increasing prevalence of encrypted data and communications represents to available investigative and interception capabilities.
