The A-League (known as the Hyundai A-League for sponsorship purposes) is the highest level association football league in Australia. Administered by Football Federation Australia, the competition was founded as a successor to the National Soccer League (1977–2004). In August 2005 the A-League's inaugural season began. The league is currently contested by ten teams; nine in Australia and one from New Zealand. Related leagues include the National Youth League and women's W-League.
