Well, this is certainly a shock. I lurk for a month, come back, and suddenly the Jerries have crossed the Channel!
Since Britain controls the DEI, I'm guessing Australia will want to assume direct control of Indonesia if London falls - it should solve your resource problems. Far be it from me to suggest treachery, but perhaps Australia's reinforcements for Britain will arrive
just after the Germans have forced a surrender...

And of course, I'm sure the new Australo-Indonesian Empire would be delighted to house Their Majesties until the Home Isles can be liberated from German control.
The Greek and Yugoslavians seem to be doing surprisingly well, though perhaps that's because the Germans have sent their best troops on a victory march through London. It's a pity that Hungary will probably jump in to grab its Yugoslavian cores, assuming it still has them in HPP. How long do you think they can hold without Australian aid?
Also, I'm curious as to why the Carrier Armour/AA upgrades are locked - I'm guessing you need a higher-tech Design Principle first?
