The 2021 Super Rugby AU season (branded as Harvey Norman Super Rugby AU for sponsorship reasons) was a professional club rugby union tournament organised by Rugby Australia. Announced on 11 November 2020, the tournament was the second season of Super Rugby AU, featuring the same 5 teams from the inaugural 2020 season, and ran from 19 February to 8 May 2021. The tournament was won by the , who defeated the 19âÂÂ16 in the final at Suncorp Stadium, winning their first Super Rugby AU title, and first Super Rugby competition since 2011.
The tournament ran parallel to New Zealand's 2021 Super Rugby Aotearoa season, and Super Rugby Trans-Tasman followed the conclusion of both seasons, a crossover tournament featuring each Australian team playing each New Zealand team once, followed by a final.
The 2021 season of Super Rugby AU saw changes to kick-offs and restarts, with a free kick awarded if the a kickoff had not taken place 30 seconds following the opposition scoring, a restart was kicked out on the full or if teammates of the kicker were not behind the ball. The free kick took place at half way. These rules were similar to those that were being used in Rugby sevens. Also the 'Golden point' law brought in during the 2020 season as tweaked so that full-time would only occur after a try was scored, rather than any form of points. Penalties and drop goals still counted towards the score during extra time, but would not end the game, with play only ending if a try was scored or the 10-minute extra time period ended. All other law changes from the 2020 season also occurred in the 2021 season.
