The National Schools Debating Championships (NSDC) are Australia's premier debating competition, coordinated by the Australian Debating Federation (ADF) and held every year in a different Australian capital. Tasmania has hosted NSDC four times, most recently in 2021.
As the sole Tasmanian affiliate of the ADF, the Tasmanian Debating Union selects the state team from a series of selection events held around the state. Tasmania has fielded a team in most Championships, and has won the Championships once, in 1980, and been Runner-Up twice.
NSDC 2024 was held in Adelaide.
