Cycling in Australia is a common form of transport, recreation and sport. Many Australians enjoy cycling because it improves their health and reduces road congestion and air pollution. The government has encouraged more people to start, with several state advertising campaigns aimed at increasing safety for those who choose to ride. There is a common perception that riding is a dangerous activity. While it is safer to walk, cycling is a safer method of transport than driving. Cycling is less popular in Australia than in Europe, however cyclists make up one in forty road deaths and one in seven serious injuries.
