:: Australia has created a super ministry combining its security agencies including the domestic spy service, border force and national police, the country’s prime minister said Tuesday, calling the “historic change” necessary to tackle terrorism.

The new Home Affairs portfolio — which uses Britain’s Home Office as a template — will be run by Immigration Minister Peter Dutton in a major shake-up of national security arrangements.

“I am announcing the most significant reform of Australia’s national intelligence and domestic security arrangements and their oversight in more than 40 years,” Prime Minister Malcolm Turnbull said in Canberra.

“We are taking the best elements of our intelligence and national security community and making them better. As terrorists evolve their methods, we have to evolve our responses.”

Boats from Asia

An office of national intelligence would be set up to help co-ordination between the agencies, with the shake-up concentrating more power in the hands of Dutton, who has been hailed by conservatives for halting the arrival of asylum-seeker boats from Asia.

Canberra lifted the terror threat alert level in September 2014 and introduced new national security laws amid concerns of attacks by individuals inspired by organizations such as ISIS.

Counter-terrorism police have also made a string of arrests since late 2014 across the nation and say they have prevented 12 terror attacks on home soil in the past few years.

But several attacks have taken place, including a cafe siege in 2014 where two hostages were killed and the murder of a Sydney police employee in 2015 by a 15-year-old boy.
