The $89 billion shipbuilding plan

THE FEDERAL GOVERNMENT'S DEFENCE SHIPBUILDING PLAN:

* $89 billion to be spent on building 12 submarines, nine frigates and 12 offshore patrol vessels for the Australian navy as well as 19 Pacific patrol boats to be given to neighbouring countries.

* It includes $1.3 billion to upgrade the Osborne Naval Shipyard in Adelaide and the plant at Henderson in Western Australia.

* The government will also establish a $25 million naval shipbuilding college in Adelaide to train workers.

* SA's shipbuilding workforce expected to swell to more than 5000 by 2026.

* Employment in the defence supply chain and allied industries expected to create another 10,000 jobs.

* The federal government has committed to using Australian workers and Australian suppliers where possible.

* The government won't put a figure on local procurement, but says anything above 60 per cent ensures the vessels are locally built.

* Work on the patrol boats will start in 2018, the frigates in 2020 and the next submarines in 2022/23.
