Facebook and Google back Labor changes to laws which break encryption

Authorities would need a fresh warrant before ordering companies to assist or build a new capability to access electronic communications

Industry groups including the representative of tech giants Facebook, Google, Twitter and Amazon, have backed several Labor amendments to the government's encryption bill.

Under Labor's plan, law enforcement agencies would require a fresh warrant before ordering tech companies to assist or build a new capability to access electronic communications and the bill's prohibition against creating a "systemic weakness" would be strengthened.
