Malcolm Turnbull is a step closer to setting up a new super security department to keep Australians safe.
The prime minister introduced draft legislation to the lower house on Thursday evening to establish a home affairs portfolio.
Under the plan, which would come into force next year, the umbrella department headed by Immigration Minister Peter Dutton would cover a bevy of agencies including the Australian Federal Police, domestic spy agency the Australian Security Intelligence Organisation and the Australian Border Force.
Mr Turnbull says the new arrangements will help counter evolving threats - from terrorism, drug trafficking, criminal syndicates and weapons smugglers to pedophile rings.
"This is how we will keep Australia safe," he told parliament.
The attorney-general will retain oversight of ministerial authorisation and warrants for ASIO and the Inspector-General of Intelligence and Security, and the Independent National Security Legislation Monitor will transfer to that department.
