Sydney’s harbor sparkle comes alive where the Opera House’s sail curves above budget-friendly fish markets at Darling Harbour. Hitch a ferry for skyline views, then explore The Rocks’ free historic lanes or Bondi’s golden sand at dawn. Picnic on cheap local produce at Flemington Markets, and watch whales from Taronga Zoo’s cliffside for less than a museum ticket—all while the city’s buzz never sleeps.
