Who held the Longest drive in any golf tournament recorded?

In 1975 George Bell of Australia shot a drive of 550 yards on the 577 yard 6th hole at St. Michaels in Sydney Australia. (He three putted for birdie) Because this was not in a PGA event, the record is not recognised. Bell was also recorded as driving 319 yards on the fly at the 1971 King of the River Driving contest at Penrith. (Source: The Complete Book of Australian Golf, By Terry Smith 1978)

Mike Austin is the holder of the "Longest Drive in a Competition" title, with a 515-yard drive, way back in 1974! John Daly's best in competition is either 414 or 440 yards. Mike Dobbyn is the current "World Long Drive" Champion, with a distance of 551 yards.

The longest drive recorded in a regulation golf match was a 515 yard drive shot by "Mighty" Mike Austin during the US National Seniors Open Championship on Sept. 25, 1974. Although if you consider long drive competitors, Mike Dobbyn owns this record with an amazing 551 yard record, making him the current Long Drive Champion.

Since the question did not specify location, one should include the efforts of Alan Shepard, when on the Moon, he took a golf club and sent a golf ball flying for "miles and miles and miles."
