Japan isolates Australia instead of attacking Midway

What if Japan tried to isolate Australia instead of attacking Midway?

Japanese forces would operate at the edge of their logistics while British and American fleets gained an opportunity to combine from the Indian and Pacific Oceans.

The farther Japan extends around Australia, the more its fleet depends on a stretched supply chain. That creates an opening for the British Eastern Fleet and the US Pacific Fleet to converge, while Allied attacks into Southeast Asia could sever isolated Japanese garrisons from their naval support.
