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.
