Grand final

A grand final is a game that decides a sports league's championship (or premiership) winning team, i.e. the conclusive game of a finals (or play-off) series. Synonymous with a championship game in North American sports, grand finals have become a significant part of Australian culture. The earliest competitions to feature a grand final were Australia's AFL (Australian rules football) and NRL (rugby league football). They influenced other competitions such as soccer's A-League, the National Basketball League, netball's ANZ Championship and European rugby league's Super League to adopt grand finals as well. Most grand finals involve a prestigious award for the player voted best on field.

The Anglo-Norman term "grand" to describe a sporting event, documented in England as "grand match" in 1836, was used in Australia from the 1850s. A steeplechase in England has been called the "Grand National Steeple Chase" ("Grand National" alone for short) since at least 1839.

Use of the term in Australian Football dates back to the first organised and widely publicised match between Melbourne Grammar School and Scotch College on 7 August 1858 at Yarra Park, Melbourne (formerly Richmond Park). The game was advertised as the "grand football match" in the Melbourne Morning Herald and several other local newspapers.

In 1859, a "grand football match" was advertised in Richmond, Tasmania for St Patrick's Day on Friday 18 March.
