 1 Lleyton Hewitt (2011, 2013) claimed three consecutive titles for Australia.The arrival of new tune-up events for the Australian Open, like the Mubadala World Tennis Championship in Abu Dhabi or the national year-end championships like the Masters France raised questions concerning Kooyong event's future.Different ways to improve the tournament studied by promoter Colin Stubs include lengthening it beyond four days (despite Roddick's withdrawal in 2009, due to the three-match format already being "too taxing" according to the American), reviving the short-lived women's event, or allowing retired players to compete.
