Donald Campbell set the world water speed record on my hometown's lake (Lake Dumbleyung) in the Great Southern Region of Western Australia, 250km's South East of the capital city of Western Australia, Perth.
Dumbleyung Lake received world recognition when Donald Campbell broke the world water speed record on it on 31 December 1964, travelling at 444.66 km/h (276.3 mph) in his boat Bluebird K7. A granite memorial to Campbell can be seen at Pussy Cat Hill, a prominent feature and vantage point to view the entire lake area

The lake nearby was discovered and named Dambeling Lake by explorers Henry Landor and Henry Maxwell Lefroy in 1843, and the current spelling was used by surveyors in the 1860s and 1870s
Donald Malcolm Campbell CBE (23 March 1921 -- 4 January 1967) was a British speed record breaker who broke eight absolute world speed records on water and on land in the 1950s and 1960s. He remains the only person to set both world land and water speed records in the same year (1964). http://en.wikipedia.org/wiki/Donald_Campbell
