So the best way to counter the Australia IC is to b**** out?
No really though, I understand. Thats kind of a good strategy for any nation though, just a bit hard to execute because Japan is spread out through islands.
Australia is an awesome naval base that gives the Allies a great deal of freedom in the Pacific. But either US or the UK must come to the fight with some naval units. While they build naval units, Japan and Germany press the attack on Russia.
Japan’s position degrades very quickly after Australia gets going, but it is almost impossible for the Allies to capture Japan itself. Far before Japan is in any real danger (with a stack of infantry and fighters on it), Germany and Japan should be able to make Russia fall. From that point, it’s really Japan and Germany vs. UK and US. In a 9 VC game, that means that Germany and Japan together have a deathgrip on 8 VCs (all in Europe and mainland Asia, probably including India, Karelia, and Moscow), but have probably lost the Phillipine Islands.
Since Japan cannot be broken, and Germany cannot be broken, the victory should go to the Axis, with a navy and air force fueled by Russian IPCs, and a positional advantage that allows Germany to threaten London itself as well as threatening Africa and Brazil with only minimal IPCs invested.
Of course, the Allies are not locked into defending Australia, but any IPCs spent there are IPCs not used elsewhere in those important early turns.
