Did some copying and pasting, and compiled a list of various cultural tipping traditions throughout the world.
Have a look see, pretty interesting:

Australia
In Australia, tipping is traditionally not common and, beyond the hospitality industry, almost all service providers will never expect a tip. Employers pay a sufficient wage and do not expect employees to supplement their income with tips. However tipping is becoming increasingly common at some establishments (particularly restaurants, cafes, upmarket hotels, and nightclubs) in cities such as Gold Coast, Sydney or Melbourne, for good to exceptional service. In recent decades, tip jars have increasingly become common in hospitality establishments, even in suburban areas of these cities. However, even in these establishments, tipping is often still seen as being an optional personal choice.
