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.
Each year between 2012 and 2025, a number of highly commended speakers were named after the conclusion of the NSDC Grand Final. In 2026, the Australian Squad was expanded from 9 speakers to 12, which subsumed the need for highly commended speakers.
