The 25-year-old stepped it up with four birdies on the back nine on Sunday to finish at 16-under overall for his second DP World Tour career win.
He held off Denmark’s Jeff Winther after he shot up the leaderboard with seven birdies in his faultless round of 64.
Victory earned Bradbury spots at the Abu Dhabi Championship and the European Tour Championship in Dubai.
“It hasn’t sunk in at all. The goal this week was to make the cut so I didn’t have to go to Korea needing to keep my card,” Bradbury said. “I guess I’ll be looking at flights to Dubai then.”
Winther could only par the last two holes and finished tied for second with countryman Thorbjorn Olesen (68), England’s Sam Bairstow (68) and Germany’s Yannik Paul (66) at Le Golf National, the course that staged the Olympics, on the outskirts of Paris.
Bradbury said he felt it could be his day when he just avoided landing in the water on the 15th and then rolled in a putt from 15 feet.
“Luckily it stayed on, and I hit a horrendous putt that went in,” he said. “Sometimes you just need that. Once I’d done that it felt like ‘there’s definitely something going for me.'”
Swedish golfer Jesper Svensson, who held a one-stroke overnight lead from Olesen and Bairstow, had a nightmare round of five over 76 to tumble down to a share of 27th.
Australia’s lone entrant David Micheluzzi ended up joint-27th at eight under after his final-round 70.
