The Australian Ambassador's residence in Washington, known as White Oaks, is a Heritage-listed brick mansion built in 1923. It was once the home of George Patton, one of the most significant and controversial military figures in US history. It has a lawn tennis court that had fallen into disrepair. Joe Hockey, Australia's Ambassador to the US, thought this was a waste, since it's the only lawn tennis court in Washington, and one of only a handful in the US north-east, so had it restored with the help of Westfield CEO Peter Lowy. Playing on grass is a dream of many tennis lovers and senior members of Congress, military leaders and foreign diplomats have all played on the court over the past year.
