No one is lightly to invade Australia .
Reason being that the government is Selig it off bit by bit to anyone that as money.
China is about to buy the rights to mine here and all the mining giants own all the rights to the valuable site here.
As for the people invasion the government is bringing in many thousands of cheap immigrants each year and they will one day out number the birth rate of Australians. so will by default own the country.
Why should any one invade using war or violence.
