The Sharks have sounded a warning to their rivals in the NSWRL Junior representative competitions with resounding round one victories.
The under-16 Matthews Cup Sharks dominated the South West Sydney Academy in Camden with an 82-0 win, while the SG Ball Sharks crushed the West Coast Pirates in Perth in registering a 76-12 triumph.
Both Sharks teams were well in control from almost the outset, building up big half time leads before going on with the job in the second period.
For the Matthews Cup Sharks winger Cameron O'Connor crossed for six tries, while centre Declan Casey managed a hat trick of four-pointers. Skipper Kai Broadhurst was on target with the boot, kicking 13 goals from 14 attempts.
The Matthews Sharks led 54-0 at half time.
It was a similar story for the Ball Sharks who travelled to Perth to play the West Coast team.
The previous two trips to WA hadn't been so fruitful for the Sharks, with a loss and a draw to show for their efforts, however this time around the visitors wouldn't be denied, the 14 tries to two victory a clear indication of their superiority.
The Sharks had nine different try scorers in the win, with Semisi Kioa and Luke Metcalf getting across the stripe three times each.
Halfback Kyle Flanagan scored a try and kicked 12 goals for a personal haul of 26 points.
The Sharks next opponets will be the Western Suburbs Magpies who had a first round bye.
Those matches are set down for next Saturday at Campbelltown Stadium as two of five games scheduled on the day, with NRL, NSW Cup and NYC trials between the Sharks and Tigers to follow the Junior Rep contests.
