From: Planning the end of the world, well out to 2023!
I usually send the Eastern Fleet to Soerbaja and there combine with the Dutch Fleet and the Asiatic Fleet.
I chew on my nails and try to ambush a japanese convoy, or a weak STF (With 1BB, 1BC, 1-2 CA, 10+Cl etc it would have to be unlucky to hit anything stronger) but as soon as japanese airpower arrives I head to Darwin or Perth, depending on the Timor/Ambon situation.
If forced to Perth I sail them around to Sydney where they become the core of SW Pac fleet.
PoW & Repulse with support from Houston & Boise are a much needed reinforcement, ans would do little in the IO.
