If you were hell bent on getting a foot hold on Aussie soil ,those very same conditions would be as big a problem for a defender trying to evict you wouldnt it ?
I mean invasion -be it far fetched both strategically and logistically - could be done over decades of low or semi intensity " conflict" rather than in one fouls swoop like our military planners think .
1) invasion fleet with large contingent of support and camp followers arrive at suitable spot in Northern Australia - say a huge rag tag fleet of military and civillian followers of an ousted warlord /defeated side somewhere close or whatever with nowhere to go but where no one would consider it possible to attack..or back to the firing squads and re education camps of their homeland.
2) suitable land for settling and producing food and vegetable oils etc is conquered in a massive ,chaotic ,bloody landing operation .
3) rather than try to "secure lines of advance " etc they dig in and try to build up more or less like the KMT did when they ran to Taiwan/Formosa in the 1940s.Cottage industries and some more efficient ones are started as a part of the plan.
4)as years go by they will trade injury and insult with the righteous owners of the land and may or may not be able to expand said foothold a ways .
To all the incensed Aussies
( or everyone else for that matter )that fume at this laughable notion - I hope you get that I am thinking in game terms here - firstly that the situation COULD arise and then secondly that it DOES.
That means that T2K conditions would apply - and that leaves something to the individual to interpret imho .
I am thinking a sort of migrations type invasion /war on Australian soil due to the upheaval of T2K rather than a "operation whatsitsname" to coldly and planned conquer .
Tha Australian military would have to be sufficiently overwhelmed by the invasion that they cant repulse it , but withdraw to positions where they know it can be contained by the size and terrain of the continent.
The newcomers would have to have resources to maintain their enclaves and to keep up enough military pressure -either trough being reinforced or through local production and conscription .
history has examples of these kind of invasions a plenty -but not from Australia afaik - except for ypu Aussies that is .
