NBL1 South

NBL1 South is a semi-professional basketball league in Victoria and Tasmania, Australia, comprising both a men's and women's competition. In 2019, Basketball Victoria partnered with the National Basketball League (NBL) to create NBL1. NBL1 South was the lone conference in 2019, with North, Central, West and East joining over the proceeding three years. Due to the COVID-19 pandemic, the NBL1 South did not have a season in 2020 and only half a season in 2021.
