How should I plan dinner and fireworks in Sydney on New Year's Eve?

Budget for the whole evening, not only the advertised dinner price. A New Year's Eve package may set a minimum spend, a seating time or a departure time before midnight. Get the fireworks view from your specific table or boat position confirmed in writing, along with drinks, cancellation terms and the route back afterward. If you choose a public vantage point instead, follow that site's current entry and food rules and do not assume you can leave and re-enter.
