Fireworks explode around the Opera House during the pre New Year's Eve celebrations in Sydney on Dec. 31, 2012.
Eager revelers camped Sunday night on the shores of Sydney Harbor to get the best vantage points as 1.5 million were expected to gather to watch the fireworks show centered on the Sydney Harbor Bridge, The Associated Press reports.
