During Imperial Japan, could Japan have conquered Australia and made a new homeland for Japanese people?

Question:

Answer:

No. Japan was not capable enough to send its army divisions to Australia. It was obvious after losing the Battles of the Coral Sea (May, 1942) and Solomon Islands (Feb, 1943). Japan lost its naval capabilities to send its ground forces any further than Papua New Guinea. Had Japan won the Battle of the Midway (Jun, 1942), and successfully kept its naval fleet for at least six more months, she could have won some more battles over the Pacific, which might have prompted its invasion into Australia.

Since the main purpose of Japanese aggression into Asia (Pacific area was not included until the U.S. broke into the war), was to secure its natural resources; iron in China, Oil in Indonesia and other materials in Southeast Asian countries, Japan did not have any realistic desire to "make a new homeland for Japanese people" in Australia.
