Australia holds a 55–45 advantage over Mexico on the Relative Advantage Index.
The margin is driven by military spending (72% of the combined total, $35.3bn) and logistics & power projection (71% of the combined total, 213). Mexico leads on active personnel 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1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
