Saudi Arabia holds a 54–46 advantage over Australia on the Relative Advantage Index.
The margin is driven by military spending (70% of the combined total, $83.2bn) and active personnel (81% of the combined total, 257.0k). Australia leads on logistics & power projection and economic size (GDP).
1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
