In keeping with its distinctly work-hard, play-hard culture, the protocol in Sydney is typically informal. During the week, business is often conducted over a long lunch, with alcohol included, and the weekend can start as early as Friday lunchtime. Both men and women usually wear suits. Business hours are officially weekdays 0900-1700, although an extended working day is very common in certain sectors and it is not unusual for people to be working well into the night or over the weekend.

Australians are a very friendly people and socialising comes easily. Nevertheless, there are a few things that may offend or annoy. The first is the use of the informal ‘G'day' - foreigners should avoid trying to emulate this overused greeting. The second is that, while out drinking, a system of ‘rounds' is observed and it is not appreciated when someone skips his or her round by not offering to pay. Gift giving is not a common practice, although a small token (such as chocolate, wine or flowers) is appropriate if invited to a home. If at a loss for conversation topics, sport is always a good choice.
