Travelers face harder looks from terrorist hunters at Australia airportsWorld | May 16, 2018
There has been growing concern over attacks by radicals inspired by Islamic State and other groups, with a foiled effort last year in Sydney to target an Etihad flight with a crude bomb.
Prime Minister Malcolm Turnbull said the new powers - which mean officers at airports no longer need a reason to ask for ID - were necessary in "dangerous times."
There was no law that requires carrying an ID, he added, "but it's hard to think of anyone that wouldn't have some ID."
He also told Melbourne radio station 3AW that recent suicide bombings in the Indonesian city of Surabaya were a reminder that authorities "need to be ever vigilant."
Passenger and baggage scanners at domestic and regional airports will also be upgraded to match those at international terminals. And screening will be strengthened for inbound air cargo and international mail, with some 190 Australian Federal Police officers deployed at airports or providing tactical and intelligence support.
Authorities say they have prevented 14 attacks in recent years.
