Australians don't expect tips, and hotels and restaurants rarely add service charges. That said, a small tip for good service is common practice and appreciated. Room service and housemaids are only tipped for special services. Taxi drivers don't expect a tip, but leaving small change will win you a smile. Guides, tour-bus drivers, and chauffeurs don't expect tips either, though they're grateful if someone in the group takes up a collection for them. No tipping is necessary—indeed, it would cause confusion—in hair salons or for theater ushers.
