Thousands are expected to pack the banks of the Brisbane River on Tuesday night in what could be the biggest New Year's Eve crowd the city has seen, with authorities advising both residents and revellers to plan ahead.

Based on previous years, police expect between 75,000 and 100,000 to turn out across the night - a figure bolstered by favourable weather and new locations to watch the family-friendly fireworks shows from.

Detective Superintendent Tony Fleming, in charge of the police operation on the night, said the event was usually "quite peaceful".

"We generally get quite busy however, as people move from the South Bank area and down through the city into the Valley area where the nightclub precinct is," he said.
