is the greatest rivalry in football." The Showdown rivalry also significantly draws upon the bitter, winner take all, competition for the two South Australian licences to join the AFL in the 1980s and early 1990s. Brisbane Lions This rivalry dates back to 1997, the inaugural season of Port Adelaide and the newly merged Brisbane Lions. In their early days, the two clubs had multiple close encounters, with a draw in two of their first three meetings. In the early 2000s, the rivalry reached its peak as the two clubs would be the most dominant of the era, meeting in multiple finals and consistently finishing at the top of the ladder from 2001 to 2004. Notable encounters include a Round 22 match in 2002 to determine the minor premiership that year, which Port Adelaide won by a single goal, and a Round 17 match in 2003 with 7 lead changes in the final quarter, which Port Adelaide won by a point. The rivalry culminated with the 2004 AFL Grand Final, where Port Adelaide defeated Brisbane to win their first premiership, and end Brisbane's chance to win a fourth consecutive. The rivalry has since died down. SANFL Norwood The rivalry between Port Adelaide and the Norwood Football Club is one of the longest standing rivalries in South Australian league football. The two clubs met for the first time in 1878, where Port Adelaide hosted Norwood, with the visitors winning 1–0. However, the rivalry between the two clubs would first begin in 1882, where Port Adelaide's first win over Norwood was controversially overruled by the league, with a follow-up game overshadowed by a misunderstanding at the gate which almost prevented Norwood players accessing the venue. The clubs met in 14 Grand Finals prior to Port Adelaide's accession into the AFL and share over 60 premierships between them. In 1884, Port Adelaide won the premiership, bringing Norwood's run of six premierships in a row to an end. In 1960, Norwood brought Port Adelaide's own record run of six premierships to an end defeating them by 27 points in the 1960 Preliminary Final. They have met in three Grand Finals following Port Adelaide's entry to the AFL, with Port Adelaide winning in 1999 and Norwood winning in 1997 and 2014. The two clubs are the only clubs in any of the elite Australian Rules Football leagues (the SANFL, WAFL, and VFL/AFL) to win six successive
