Chief Superintendent Stephen Dabinett said about half-a-million people were expected to line the banks of the Brisbane River for the celebration.
“We are well versed in planning and preparing for major events, and Riverfire is no exception,” Dabinett said.

Extra police were expected to patrol through the city, including at South Bank, Kangaroo Point and other vantage points.
On Thursday, the RAAF conducted practice runs through the city with the helicopters, followed by the jet fly-through on Friday.
