Tipping is not expected or required in Australia. The minimum wage in Australia is reviewed yearly, and as of 2017 it was set at A$17.70 per hour (A$22.125 for casual employees) and this is fairly standard across all types of venues. Tipping at cafés and restaurants (especially for a large party), and tipping of taxi drivers and home food deliverers is again, not required or expected. However many people tend to round up the amount owed while indicating that they are happy to let the worker "keep the change".
