They also managed to match their highest score against Canberra, having also notched 44 points over the Raiders in 1982.
It was another disappointing showing from the Raiders in front of their home crowd.
David Furner's men had much to prove in their first game back since losing captain Terry Campese to a season-ending knee injury, but came off second best in the battle of the forwards.
The game had looked wide open nearing halftime when Josh McCrone posted his second try to pin the margin back to four points at 16-12.
But two tries in seven minutes to Cronulla before the break pushed their lead out from four to 16, and they never looked back.
They posted another three tries to two in the second half for a clear victory.
"They were just too enthusiastic for us," Raiders' forward Tom Learoyd-Lahrs said, before urging the home crowd to stick with the injury-hit club.
John Williams scored two tries for Cronulla, while McCrone was one of Canberra's best and finished with the same tally.
The last-minute inclusion of star fullback Josh Dugan failed to pay dividends for the Raiders, although he did manage a classy try in the second half when the game was all but lost.
