The Great Southern Slam (TGSS) is the largest competitive roller derby event in the world,[1] contested by teams from New Zealand and Australia.
TGSS was created and continues to be both hosted and run by volunteers from Adelaide Roller Derby.
The group winners and other teams with the highest point difference qualify for the quarter-finals, and the tournament then continues on a knockout basis.
2024's TGSS was held at the Adelaide Showground and included 45 teams from Australia and New Zealand playing across 65 games over three divisions.
For the first time ever TGSS doubled as the WFTDA Oceania Regional Championships, which meant that the first and second place winners of Division 1 will earned a place in the 2024 WFTDA World Championships to be held in Portland, Oregon.
