South Korea holds a 54–46 advantage over Australia on the Relative Advantage Index.
The margin is driven by military spending (57% of the combined total, $47.8bn) and active personnel (90% of the combined total, 555.0k). Australia leads on logistics & power projection.
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side. Those factors are excluded and the remaining weights renormalised, never substituted.
