The Sharks prevailed 24-20 in a back-and-forth battle with the Bulldogs in the NSW Women's Premiership.
Going try-for-try, Cronulla took a two-point lead into halftime, thanks to a first-half double from Marewa Samson.
Canterbury took back the lead quickly after the break to make it 20-16, but as the Sharks stared down the barrel of a 4th loss for the season, they turned up the intensity.
Alesha Williams grabbed her second try of the game, and Ella Ropata missed the conversion to keep the score level at 20 all.
To cap off a great day for the outside backs, Williams' fellow winger Lacie Bowing also dove over to give Cronulla a 4-point lead with 17 minutes remaining.
The Sharks would hang on and jag a crucial 2 points to move the reigning premiers up to 8th on the Women's Premiership ladder.
Samson was the stand-out for the black, white and blue; her first-half double proved pivotal.
The 21-year-old had her best game at centre this season, after moving from the backrow last year.
The 8th-placed Sharks now face the 9th-placed Tigers at Lidcombe Oval on Saturday at 2:00pm.
