Ormsby finished with a flurry, capping his round with birdies at 16, 17 and 18 to surge up the leaderboard at the Kennemer Golf and Country Club on the Dutch North Sea coast..
"That's the lowest score I've had in any round, let alone tournament golf," Ormsby said. "I've worked pretty hard the last few weeks. I've had five weeks off back in Australia, and it's nice to get back and on the front foot."
Hours earlier -- and playing the back nine first -- Lawrie, The Open's champion in 1999, eagled the par-5 12th and birdied 16, 17 and 18, too.
"The 59 did cross my mind," Lawrie said. "I had a long putt on the seventh -- my 16th -- for eagle after a lovely three wood in there, and had that popped in there I would have only had to birdie one of the last two to make it. But I'm very happy with 61."
Richard Bland of England also gave himself a chance of shooting the European Tour's first 59. Bland was 8 under with three holes to play but parred them all to finish the round alone in second place.
"I hit a lot of good shots out there," Bland said. "It's always nice to make a good start. It wasn't easy -- we probably had a two-club wind most of the day."
Dutch favorite Joost Luiten, the 2013 champion, was tied for fourth with four other players after 63s.
Tom Watson, who had an ace during Wednesday's practice round, had three birdies and two bogies on his way to a 1-under 69.
