It was the first grand final of the re-unified National Rugby League and featured minor premiers and the previous year's Super League premiers, the Brisbane Broncos against the Canterbury-Bankstown Bulldogs. It was to be the first grand final under the National Rugby League partnership's administration and the last to be played at the Sydney Football Stadium. It was also the first time these two sides had met in a grand final.

Brisbane scored first but by half time trailed the Canterbury side 10–12. However, the Brisbane club scored 28 unanswered points in the second half, winning 12–38 and equaling the second highest score for a team in grand final history.
