Government agencies and private companies could have access to round-the-clock cyber security support as part of a host of new proposals.
An independent review, published on Tuesday, made 23 recommendations aimed at strengthening and streamlining Australia's intelligence community.
Central to that is establishing an Office of National Intelligence to co-ordinate activities across 10 agencies, their 7000 staff and a budget nearing $2 billion.
"It is clear to us that on size alone, the Australian government's intelligence activities supporting national security are now a major enterprise," Michael L'Estrange, Stephen Merchant and Sir Ian Lobban said in their report.
"They would benefit from being managed as such."
The new office would fall within the prime minister's portfolio and be headed by a director-general, who will be the PM's principal advisor on intelligence.
It is separate to the new Home Affairs portfolio, which Peter Dutton will lead.
While they won't have the power to direct specific activities of agencies, they will be responsible for co-ordinating and prioritising what needs to be done.
The office would also be in charge of planning, evaluating agencies' performance, and the sharing of data and analyses.
It will also provide the prime minister with a written personal overview on key issues for intelligence agencies every two weeks, and fortnightly meetings.
Another significant proposal is to make the Australian Cyber Security Centre part of the Defence Department's Australian Signals Directorate.
Alastair MacGibbon, the prime minister's special advisor on cyber security, will lead the centre and provide a six-monthly report to cabinet.
It will operate 24/7 to respond to serious cyber incidents.
"This capability will better meet the needs of the community and the government in relation to rapidly emerging cyber events and we've seen some examples of that very recently," Prime Minister Malcolm Turnbull said.
