They are the competition’s most dangerous attacking force, but Stingrays coach Brett Wallin insists Illawarra still have work to do to complete their rise to the top of the ladder.
While the Rays have banged in a league best 29 goals through the opening eight games, Wallin believes his side have room for improvement at the opposite end of the pitch.
Illawarra have conceded 20 goals already this season heading into Sunday’s trip away to play North Shore Mariners at Valentine Sports Park.
"We have got some brilliant attacking players but still need to work on our defence," Wallin said.
"Caitlin Cooper went back into defence last week and did a great job on Tara Andrews. When she is back there it is a different ball game for us."
Illawarra (15 points) are level with both Sydney University and Blacktown Spartans, with all three trailing ladder leaders Macarthur by two points.
