Arsenal began the defence of their title in full-swing with a 4-0 victory over Blackburn Rovers.
And it took only seven minutes before Smith registered her first goal of the season.
Smith scored with a delightful chip over Danielle Hill in the Blackburn goal, after she had been given too much space just inside the box.
Smith then popped up in the 17th minute converting from six yards after some neat one-two passing with Carney coming in off the left flank.
Jayne Ludlow added a third just before the break when a lose ball dropped to her just outside the box and she unleashed a sweet left-foot volley that sailed over the goalkeeper.
In the second period Blackburn adjusted their 1st half 4-5-1 shape to 4-4-2 adding another striker into the attack but Arsenal continued to dominate the possession allowing Blackburn only the sporadic attack.
Smith then completed her hattrick in the 56th minute with another easy tap-in after Gemma Davison had danced herself into the box to unleash a great strike that goalkeeper Hill could only parry to the unmarked Smith.
As the Blackburn defence tired Davison continued to cause problems with her quick and skilful runs through the middle and down the right flank but several chances went unpunished.
Three league debutants were then introduced to the game as Niamh Fahey, Dannii Bird and Eartha Pond were all subbed on.
And it was Dannii Bird that went closest in almost grabbing herself a debut goal five minutes from the end as her 20-yard strike just flew wide of the post.
