You really don't know your countries history do you? How many lives were saved by armed civilians when the Japanese invaded your country?
None. NZ and Oz were never invaded.
Australia had a Japanese recon force land on its shores as late as 1944. It remained for around three days. The defensive line was called the Brisbane line and all north of that line was to be ceded to the Japanese.
I think they drew a line from Brisbane to Adelaide - anything not under that line was up for grabs. Apparently Perth has never forgiven Canberra for that...Problem is, with a country this big, with a small population it is too hard to defend. Let alone, at the time, they thought they wree giving up sand and rocks...
Yeah, a recon force wouldn't surprise me.
