This is a list of National Soccer League (NSL) champions. The NSL was the elite football (soccer) competition in Australia from 1977 until 2004,^[1] when the competition was scrapped and replaced in 2005 by the fully professional A-League.^[2]

National Soccer League Champions

From 1977 until 1983, the winner was the top placed team at the end of the season. From 1984 until 1986, the competition was split into two conferences, with playoffs to decide two grand finalists who met over two legs. In 1987 the system reverted to the pre 1984 system. From 1988 until the demise of the league in 2004, various playoff systems were used to decide the champion.

Playoff Series Champions

From 1977–1983 and 1987, the top placed team at the end of the regular season was declared champion. However a compromise format was devised between the traditional first past the post system and the Australian system of finals. A Playoff series was conducted in these years except for the 1977, 1981 & 1983 seasons, however the winner of the Playoff Series didn't become champion of the NSL.
