The biggest event on Sydney's Jazz calendar is the Manly International Jazz Festival, but Darling Harbour's three-day event is by no means small. It is standing room only on the forecourt each Queen's Birthday long weekend, when thousands of jazz fans get into the groove. With performances from household names like James Morrison and Vince Jones, this is a mostly-mainstream jazz festival, in a stunning open-air location on the shores of Sydney Harbour. Most events are free.
