How did world war 2 shape australia?

Great! The Australian economy received a huge boost from the war, as most consumer goods were restricted, meaning that people could not spend on stuff that they didn't really need. Strict rationing of food also meant that people did not over-indulge. This helped the Australians' personal savings rise greatly. Secondly, manpowering and essentials industries meant that there was close to full employment, of course accelerating the economy.
