Thanks, Mate!
I wasn't quite sure about its capability. How would you suggest that Australia deal with the threat of ICBM's targeting South Korea, Japan and other Allies? Have you other links for Australian Space Tracking capability? I do not have access to that link.
There are many, this topic is very detailed.

Australia tracks a lot of satellites, US, Europe, Japan and France all have agreements with Australia.
Combined with Australia's other radar systems, we are a very significant player. Not all of these are interconnected of course. Or designed around targeting. Of course with no suitable interception capability there is no point.
Ideally for protection:
* SM-3 capability for the AWD (systems and say 8 missiles)
* SM-3 capability for the first 3 F-5000 aegis based frigates (systems).
* SM-6 for the AWD and the first 3 F-5000 frigates, but compatible with the entire Sea5000 ships.
That would give us 6 very capable ships. Anywhere we need a ballistic missile shield, SM-3 doing high end, mid course intercepts, SM-6 for terminal intercepts.
Really it costs an AWD system upgrade (inevitable anyway) and 8 missiles.
With 6 ships, that is going to allow a reasonable capability. US is of course going to do all the heavy lifting, but in many cases it might be seen as escalating the conflict to have US ships doing the heavy work.
In that case having a situation like Australia/South Korea and Japan able to enforce a no fly zone.Combined with other allies like Spain or the dutch (who have contributed data to a SM-3 launch) there are then other options.
That sort of capability would also be a deterrent in any MRBM/LRBM/ICBM race occurring in SEA.
