Australia Etiquette
There is very little in the way of built-in restaurant charges in Australia (except for the Goods and Services tax, which is included in the total of the bill), and tipping is far from mandatory. However, Australia's tipping etiquette has evolved, and tipping has become more commonplace in more expensive restaurants for very good service — and 10% is the usual figure. The only exception to the rule is that large groups will often be expected to leave a tip.
Another word of note is that etiquette in Australia tends to be more casual than in other countries — even in expensive restaurants, which is in keeping with Australia’s relaxed national character.
