Andrews sits atop the leaderboard with a 7-under-par 64. Fellow Queenslander Chris Downes is one shot back thanks to an eagle and four birdies, while nine players, including defending champion David Podlich, share third after 66s.
Also at 5-under are promising New Zealander Gareth Paddison and Queenslands Michael Wright, who needed just 27 strokes to get around the back nine as 41 players shot scores in the 60s.
Andrews collected seven birdies to set the opening day pace, but wasnt completely happy with his round: 'I drove badly but putted extremely well,' he said. 'If I can improve my driving, I'll be a chance.'
Andrews needed just 25 putts as he sank five of them from less than 15 feet, and while he likes the course and the conditions involved, says he thinks its going to take a low total to win.
'I like the course because of the wind. It can be different every day,' said Andrews.
Andrews believes a winning total could be about 19-under if conditions remained. 'It's a reasonably comfortable course if there's not much wind.'
Three-over at the turn, Wright went eagle, eagle, par, birdie over the closing holes to completely turn his round on its head, and is now level with Shane Tait of Queensland and New South Welshman.
Tournament favourite Greg Turner had a day he would rather forget, shooting a 1-over 72, and says unless he improves markedly will be a spectator on the weekend: 'If I play like that tomorrow, I'll be on holiday sooner than I was hoping,' he said.
