Eastern Suburbs had made their first grand final in 15 years but the moment was quickly spoiled by St George, who ran out the locals 31-6 at the SCG.
Another strong crowd of 53,156 came through the turnstiles to watch the St George machine roll on.
Reg Gasnier scored the first two tries of the day with his trademark turn of speed.
In the end, the Saints' star power proved too much for Easts, who crumbled in defence as the backline led by Reg Gasnier ran them in circles.
Kevin Ryan (St George) and Brian Wright (Easts) were sent off for fighting as the Dragons again outmuscled their opposition on the biggest stage.
However it was the speed of their backs that did most of the damage.
The Saints ran in seven tries, five of which were converted by Brian Graham.
Captain-coach Ken Kearney became the oldest player to appear in a grand final at 36 and also equalled Jack Rayner's (South Sydney) record of five premierships won as a captain.
At this point, St George were no longer just the big men of the competition, but a formidable force in rugby league that combined muscle, speed and class across the park.
St George Dragons 31. Tries: Gasnier (2), King (2), Bugden, Brown, Provan. Goals: Graham (5).
