Verdict

Australia holds a 95–5 advantage over Papua New Guinea on the Relative Advantage Index, a decisive margin.

The margin is driven by military spending (100% of the combined total, $35.3bn) and economic size (GDP) (98% of the combined total, $1.8tn).

1 factor — nuclear warheads — could not be scored because the figure is unpublished for at least one side.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.
