The government-proposed changes to national security laws are part of a review into counter-terrorism. The new measures would mean the Australian Defense Force (ADF) could be called in sooner to help police deal with threats. They were prompted by criticism of the speed with which police responded to the 2014 siege in a cafe in Sydney. Current legislation prevents police from calling on the ADF until they have reached the limit of their capability. Under the new measures, the military would also provide specialized training to police forces.
