Paul Powell took the lead at the Australian PGA Seniors Championship at Mollymook Hilltop Golf Club by firing a 1-under 71 in round one.

Considering the blustery conditions, the Victorian played an almost flawless round of golf with an only one bogey at the difficult 398m, par-4, 4th hole.

"It's a tough course out there but I kept the ball in play and chipped really well," said Powell.

"I've been working on my mental approach to the game and today it all seemed to come together."

The 55-year-old Seniors player is leading by one shot from four of his fellow Professionals including E-Z-GO PGA Legends Tour Order of Merit leader Tim Elliott and PGA Legends Tour Rookie Martin Pettigrew; the Kiwi is playing his first event on the E-Z-GO PGA Legends Tour.

"It's great to be out playing. I've been preparing for this since turning 50 earlier in the year so I'm hoping for a good week," said Pettigrew.

Other notable scores from this first day are Mark Tickle and Brad Burns tied 2nd; Legends David Merriman and Michael Harwood are respectively 2 and 3 shots over the card while Peter O'Malley sits at T16 with 4-over 76.

The Defending Champion Rodger Davis, struggling with the flu, did not play his best golf with an opening round of 9-over 81 to sit in a tie for 53rd position.
