And if they tried it in "the Wet" as we call it, they would have just got bogged.
Units such as the Northern Australia Observer Unit (the "Nackeroos") were raised from local white fellahs and aboriginies (the unit still exists today as "NORFORCE") to surveil and harass any Japs that landed.
Even today, the defence of northern Australia is viewed more along the lines of defending "islands" of infrastructure and population, rather then trying to deny it all. An un-resupplied invasion would wither and die in the inhospitable terrain.
Hence the ADF's reliance on submarines and maritime strike aircraft (to cut the enemy's maritime supply lines) and light mobile land forces to bleed the enemy with a thousand cuts.
