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.

History

The South Australian Metropolitan Basketball Association was founded in 1936. This organisation later became known as the Basketball Association of South Australia (BASA). The sport of basketball in the state of South Australia was boosted after World War II by the influx of emigrants from Europe especially from the Baltic countries. In 2006, Basketball South Australia was formed following the dissolution of BASA. The first official South Australian State Basketball League season took place in 1957. During the 1990s, the league was known under sponsor names "State Bank League" and "BankSA League". In 1998, the SA State League joined the Continental Basketball Association (CBA) as the association's Central Conference. In 1999, the CBA was restructured as the Australian Basketball Association (ABA). The ABA would not allow South Australia maintaining its competition as a "state league" and required two alterations: a name change and some representation in the competition from outside Adelaide. The competition was initially titled Central Conference of the Australian Basketball Association and later the Central Australian Basketball League (Central ABL) name was adopted and remained in place until 2014, despite the ABA folding in 2008. The league was rebranded as Premier League in 2015. In February 2020, Basketball South Australia and the National Basketball League (NBL) announced a new partnership to bring NBL1 to South Australia, with the Premier League being renamed NBL1 Central and becoming the central conference of the NBL1. However, due to the COVID-19 pandemic, the 2020 season was cancelled.
