The Sheffield Shield is the domestic first-class cricket competition of Australia. The tournament is contested between teams from the six states of Australia. Prior to the Shield being established, a number of inter colonial matches were played. The Shield, donated by Lord Sheffield, was first contested during the 1892–93 season, between New South Wales, South Australia and Victoria. Queensland was admitted for the 1926–27 season, Western Australia for the 1947–48 season and Tasmania for the 1977–78 season.
The competition is contested in a double-round robin format, with each team playing every other team in two home-and-away matches. Points are awarded based on wins, losses, draws and ties, with the top two teams playing a final at the end of the season. Regular matches last for four days; the final lasts for five days. New South Wales have won the most titles, with 46 overall. The current champions are Victoria.
