It's summertime in Australia's largest city but that doesn't stop Sydney-siders from getting in the Christmas spirit. From enormous inflatable Santas bobbing in Darling Harbour and a spectacular lightshow brightening up Sydney Town Hall, to nightly carol concerts and festive turkey BBQs on the beach, there's no more atmospheric time to be in the city. Save some energy for the after Christmas too - the famous Sydney to Hobart yacht race departs from Aussie shores to huge crowds on Boxing Day and the mammoth New Year celebrations in Sydney Harbour feature a breathtaking fireworks display, boat procession and street party.
