Let's remember a few facts.
Japan launched its "Southern Offensive" across a huge expanse of the globe with one objective. To cause, to use a modern term, "shock and awe" to the Allied powers. Quickly gobbling up isolated bases within their sphere of control (Hong Kong, Guam, Wake) and overrunning poorly defended colonial territory in SE Asia, the Allies were to be so demoralized that they would sue for peace. They expected a cakewalk, but reality intervened. In spite of rapid victories in Malaya, Burma and the Philippines, and the rapid seizure of Rabaul, the Japanese quickly found themselves overextended. Resistance at Wake Island delayed the Japanese timetable two weeks and required additional forced to accomplish. Ditto the Philippines, which held out until May and resulted in the commander of the operation being relieved. The surprise attack by the Lexington and Yorktown on the Lea-Salamaua landings 10 March, 1942 cost the Japanese three transports critical to further expansion and damage to other ships resulting in a month long delay in launching the Port Moresby operation. Without these critical delays we don't know how much the Japanese could have achieved in severing the lines of communication to the US and UK. Would Australia stand alone against the Japanese if their Allies could not support them? Or would they accept the new status quo? Japan does not have to fight for every inch of Australia, just seize the key ports.
Thats quite right. There were a number of Aussie special forces hiding out in the jungle (with huge help and support of the local indigenous people) making guerrilla style hit and run tactics holding up to 2000 Japanese troops for weeks, and totally cut off from any chain of command as there was no effective radios until they pieced one together from stolen parts after raids into occupied territories. People often overlook the little contributions, concentrating on major battles that in some cases were no more important than nuisance raids.
