A background article on the Australian-US alliance, which opens with the 1943 DoD advice for US troops going to Australia:
You're going to meet a people who like Americans and whom you will like. The Australians have much in common with us – they're a pioneer people: they believe in personal freedom: they love sports...But there are a lot of differences too – like tea, central heating, the best way to send Sunday morning, or saluting officers and such. You'll find out about all those, but the main point is they like us, and we like them.

One trusts that the USMC facilities in Darwin have central heating!
