Defence suppliers in South Australia.
We work with South Australian suppliers from Melbourne and Brisbane. South Australia has its own defence agency and supplier directory, so this page covers what's local to you.
South Australia is where Australia's naval ships are being built.
The frigates are under way at Osborne and the submarine yard is being built, and both need suppliers.
