St George beat Western Suburbs 20-9 in front of a bumper crowd at the SCG to take out their third premiership in a row.
Wests were coming off a 10-man victory over Manly the previous week but had few answers to the Dragons who ran away with a 20-9 win on the hallowed turf.
Again it was a second half masterclass by the Saints that did the job.
Leading 5-2 at the change of ends, St George piled on three tries in the final 40 minutes, while Brian 'Poppa' Clay produced a man of the match defensive display to celebrate his birthday.
It was a remarkable turnaround for St George, who had been mauled 34-10 against Wests just two weeks earlier at the SCG.
The Sydney Morning Herald recorded the match as the most 'savage' game of the year, with punches and high shots a plenty in a brutal decider.
Despite being penalised 20 times to Wests' nine, St George ultimately won the fight and their third straight premiership.
Norm Provan proved his worth by scoring two tries, including an intercept at the death to send the partisan SCG crowd of 62,283 into jubilation.
This was history in the making.
St George Dragons 20. Tries: N. Provan (2), Bugden, Lumsden. Goals: Bath (4).
