But winning the tournament is of little concern for Lee - as long as he finishes inside the top 19 and ties he will progress to the final qualifying stage later this month.
The same is true for Alker, also playing at the Bear Creek Golf Club. He shot a five under 67 on moving day to rise to a share of 18th heading into tomorrow's final round.
He will probably need to shoot under par again tomorrow to progress, a scenario shared by compatriot Wilkinson at his tournament in Florida.
The former PGA Tour player sits in a share for 15th after shooting even par in the third round at Panama City. He, too, needs to finish inside the top 19 and ties.
It wasn't all good news for New Zealanders in Q School, however, with Josh Geary bowing out of qualifying after finishing 59th at a qualifying tournament in Texas.
If Lee, Alker and Wilkinson do advance, they will join about 150 other players in a quest for the 25 cards available for the final stage.
Meanwhile, Campbell continued his recent resurgence by storming to the halfway lead at the Hong Kong Open. The 43-year-old fired a six under par 64 in round two to reach a nine under par total and take a one shot advantage into the weekend.
"I'm just happy to be in a position to have a chance for the weekend," he told the European Tour website. "That's why we play the game, that's why I didn't give up."
The former US Open champion appeared back to his best as he made the turn in 30 before making it four birdies in a row on the 10th hole and adding a final birdie at the last.
"There have been times where I wanted to throw it in," he said. "But it doesn't go away, the talent. It's always with you. It never goes away, it just hides now and then. I decided to just keep on working hard and that was it."
In Australia, three Kiwis are in the hunt at the Australian Masters midway through the third round. Michael Hendry slipped back from his overnight position of second, shooting six over through 15 holes to sit in a tie for 10th, but Mark Brown and Gareth Paddison enjoyed more luck.
Brown fired a five under par round to move to fifth, seven shots behind leaders Adam Scott and Ian Poulter, while Paddison shot three under for the day to sit a stroke back.
