The way I would do this:
Build three transports on J1. Move your sea zone 20 transport to Palau Island on J1 to pluck the lone infantry (if you don’t want to leave it alone, also bring in a cruiser to cover it). Leave the mini fleet off the Carolines in position. Leave the transport in sea zone 6, or move the transport from sea zone 19 back to sea zone 6. This gives you five loaded transports to move on J2 (including the one in sea zone 34) for your attack. Position your southern fleet elements for your J2 DoW. Consider not using the bombers in Yunnan and landing them in Caroline Islands instead.
On J2, declare war. Take New Guinea, depriving ANZAC of all its objectives. Clear the sea zone off Queensland and kill anything that can reach that sea zone. Move your four loaded transports with at least two full carriers and other naval forces to Caroline Islands, bring in your strat bombers if you didn’t already get them here, and take three fighters from Japan to cover the fleet. If possible, you also want to take Western Australia so that your bombers from Caroline Islands have a good place to land.
On J3, invade New South Wales with five loaded transports, two carriers, and as many planes as you can reach. You should win if ANZAC sent all its fighters and a couple of infantry to Java – the fighters cannot make it back on A2, and frankly ANZAC has no good options at this point. If have more force than you need, divert transports to money islands and possibly New Zealand because you are definitely going to need as much income as possible as fast as possible.
If this does work, you have all of ANZAC on J4, which totals up to 15 more IPCs including bonuses, and you are well positioned to complete the capture of the money islands if you haven’t already.
Doing this later than J3 gives ANZAC more time to collect income and build defenses (including the full return of its fighters), which is the last thing you want to happen. That’s why I would DoW on J2, before ANZAC becomes too tough to crack and requires more than five loaded transports.
The big problem with this is that the entire thing is obvious as a clown in church if anyone is paying attention once you move additional naval elements to the Caroline Islands on J1 – you’re moving before the Allied players, so they cannot possibly miss the threat under any kind of reasonable examination. So, you have to do it without moving additional fleet elements to the Carolines on J1, and that makes it kind of hard to kill everything you need to kill without a little lucky Allied assistance – you really want ANZAC ships to move west on A1 and for the US to pull its fleet back to San Francisco on US1. If not, on US2 the US can make life really nasty for you by deploying blockers to sea zones 46 and 49, and the free ship kills are little consolation for the lost turn – you will still kill ANZAC on J4, but then it has probably cost you enough time to make the Pacific a tough battle for you, and it will cost you a lot more in terms of lost units on defense – your five loaded transports might barely be enough with a lucky defensive roll.
