The combined Daytime Population of Australia is over 160 million. This effectively means that the resident population of the country is present in multiple places every day. For example, for a person in paid employment who works outside of the home, the home and office count as two places. Going to lunch will count as a third place and picking up a carton of milk will be the fourth.
