A foreign super power who would target one of the richest and beautiful countries in the world. If WW2 was not enough of a reason why ! look at ukraine. An elephant is afraid of nothing but bee's ! So the biggest lion in the world can come up and the elephant will throw him 10 meters in the air.
So the biggest land animal in the world is afraid on only bee's ! And the ironic thing is a bee's sting cannot even penetrate it's hide.
Australia MUST HAVE IT'S OWN NUCLEAR ARSENAL for our children and grand children. We don't know scientists say there may even be world wars over counties running out of water in the next 50 years!
America I love but it's not the same security as decades past. America will always recover but they would understandably protect their own country if things got bad. Australia could end up a sitting duck. Leave it long enough and it will happen for just the trillions of dollars in the countries un-mined gold fields!
