As of the end of 2023, there have been 26 NRL Premierships and 116 including the lesser, state premierships,. This is a list of all the grand finals that were played to decide those premierships.
Between 1912 and 1925, and again in 1937, the NSW premiership was decided on a first-past-the-post basis, with a final only played if two teams finished with an equal amount of competition points. This happened in 1916, 1922, 1923 and 1924.
From 1926 until 1953, the second amended Argus System was used, whereby the minor premiers had the right to challenge the winner of the final to a grand final to decide the premiership.
From 1954, the grand final became the only way to determine the premiership.
