Bisley said the number of infringements was a reminder to everybody to be vigilant while driving.
"Driving towards Links Avenue from any direction, drivers will pass between three to five signs about the trial. If you don't notice them, safety is clearly an issue," said Bisley.
Some 8500 warning letters were sent to drivers who drove through the bus lane in the first two weeks of the trial.
Council said the letter explained that the bus lane had been used and that future infringement would mean the standard $150 bus lane fine would apply.
Team leader of regulation monitoring Stuart Goodman said 8000 infringement notices were issued to drivers who have used the bus lane illegally.
"At least 25 per cent of those are to drivers who have used the lane before and have received a warning letter or previous infringement.
"We'd like to see more compliance as the trial progresses. The goal of the bus lane, and the subsequent infringement notices, is to stop drivers using Links Avenue as a through road."
