Australia's Karen Lunn shot a six-under-par 66 to lead by one after the first round of the UNIQA Ladies Golf Open, presented by Raiffeisen, in Austria.
Lunn, the 1993 British Open champion, carded six birdies at Golf Club Fohrenwald in Wiener Neustadt to go clear of compatriot Vicky Thomas, Sweden's Emma Zackrisson and Germany's Anja Monke and Denise Charlotte-Becker.
"I've been playing really well over the last few weeks and the scores haven't been reflecting how well I've been playing," said Lunn.
"I have a good feeling on these greens. Even though I didn't hole a lot of putts, I've putted well here before."
Welsh rookie Lydia Hall, Scotland's Clare Queen, Italian Diana Luna, Caroline Afonso of France and Beth Allen of the United States were all two shots off the pace on four under.
The 20-year-old Hall said: "I just played solid golf, hitting fairways, hitting good approach shots and holing putts here and there."
Defending champion Laura Davies' opening 71 left her in a share of 26th.
Davies hit her second shot into the water at the par-five 18th hole but still managed to salvage a par.
"It was a disappointing start and I'm too far back after day one. I played a lot better than that," said the former European number one.
