NBL1 Central, formerly the Premier League, is a semi-professional basketball league in South Australia, comprising both a men's and women's competition. In 2020, Basketball South Australia partnered with the National Basketball League (NBL) to bring NBL1 to South Australia. NBL1 replaced the former Premier League to create more professional pathways and opportunities for males and females playing basketball in South Australia. As a result, the Premier League became the central conference of NBL1.
