Australia is well-known as a sports powerhouse. Some popular sports in Australia are not familiar in Japan, but knowing about them will provide a window into further understanding Australia and might even serve as an ice-breaker when striking up conversations with people you get to know in the country. Moreover, sports even influence the political schedule, e.g., no national elections are ever held in the second half of September when the Australian rules football or rugby league seasons are coming to a head. The "Bodyline series" and "Underarm Incident" in cricket have even influenced diplomatic relations for Australia. The sites introduced here primarily center on those created for sports administration in the country, national athlete development centers, popular sports associations/organizations, and media that can be viewed for free.
