As stated, the Java invasion force will be off Semarang, about 55 NMs, lil NNW, Feb 27-29. All kinds of action there.
If you go west and look at Merak, the harbor to the right of the label contains a large invasion force on March 2. In the Sundra Strait at Merak another large invasion force will come through the Strait heading to Christmas Island, just sit outside the strait around March 7.
The JPS make a carrier run into the Indian ocean about that time, if you get on a strait line from Christmas Island to Darwin after March 9, you might get lucky...
After that I head to the Solmons for April and May...Coral Sea, Port Moresby invasion force, ect...
