The Suns won 11.6 (72) to 9.10 (64) after trailing at every change, and by 23 points at three-quarter time.

There was a dispute over whether Bomaderry booted four goals or five goals in the second quarter and a second disparity between the club and goal umpire's scoring in the fourth quarter, but the Suns deserved their comeback victory.

Shellharbour were outplayed by premiers Wollongong Bulldogs in round two in their only other match of a rain-marred season, but Suns coach Andy Wilton was full of praise for his players for their fighting effort against a strong Bomaderry outfit.

"First half Bomo were running free and doing as they wished too often, but we addressed it at half-time," Wilton said.

"We were a lot more physical, a lot more accountable second half and we wore them down.

"We didn't give them cheap possessions, pressured them a lot more; made better use of the ball and just fought it right out.

"I'm proud of our guys.

"The scoring matter wasn't something I was aware off and it didn't impact on the result."

Troy Cole led the way for the Suns, while Mitch Bates was a major influence after half-time on the wing, and full forwards Brendan White and Ramez Dagher also key contributors.

In other round four games, Northern Districts claimed their first win, a tight 12.7 (79) to 8.10 (58) over Nowra at West Street Oval. Wollongong Lions made a resounding 67-point win over Kiama at North Dalton Park. and look a major premiership threat, having slammed the Power 18.13 (121) to 8.6 (54).

Ben Griffin and Ben Rawson played well for Kiama, while Ricky Neels booted three goals for the visitors.

Premiers Bulldogs had the round four bye and are away to Kiama in round five on Saturday. Norths host Bomaderry and Nowra are at home to Shellharbour in other Division 1 games.
