The Queensland Government is reaping millions of dollars in revenue benefits following the rollout of new speed cameras and updated red light cameras.

The latest Government figures show $396m was made last year on fines, expected to grow to $444m in the next financial year. By 2021, the figure is expected to exceed half a billion dollars.

A spokeswoman for the Department of Transport and Main Roads says, "Ideally no revenue would be collected from the Camera Detected Offence Program, however any money collected in excess of running the program is required to be reinvested into road safety programs”
