Sydney in December
When to go
Destination NSW says seasons in Sydney are opposite to those in the Northern Hemisphere and that summer runs from December to February, so the month sits in the warm season. Two official sets of dates shape it: the NSW Government's public holidays for Christmas, Boxing Day and the additional day that follows, and the City of Sydney's New Year's Eve fireworks, which its official site schedules for an early display and another at midnight. Check both against your trip dates.

Flights
The Department of Home Affairs' Electronic Travel Authority page lists the United States of America among the eligible passports and says how long you can stay after each entry, so read it while you compare flights. Sydney Airport's own website gives the train travel time into the city, which is worth weighing when you compare arrival times. For US government guidance, see the State Department's page for Australia, and check the airlines directly for current flight and route information.

Where to stay
The City of Sydney's New Year's Eve visitor page puts booking accommodation as early as possible on its before-you-arrive list, so compare dates and cancellation terms early. The same page says it does not recommend driving on New Year's Eve because of road closures, changed traffic conditions and limited parking, so check how you would get to and from the harbour from each place you consider.
