More than two years after a drop in the speed limit, a camera at Windang is still catching hundreds of motorists every month.
This financial year alone, there's been more than a 300 per cent increase in speeding fines issued compared to the years before the speed limit change.
After a spate of accidents, Roads and Maritime Services conducted a review of the speed limit along Windang Road.
In May 2017 Roads and Maritime Services announced a cut in the speed limit through the Windang CBD - from 70km/h to 60km/h.
The area covered by that speed limit cut takes in a red-light speed camera at the Boronia Avenue intersection.
In the 2017-18 financial year that camera saw a huge surge in the monetary value of fines compared to the previous year.
It issued fines with a face value of $1.13 million - an almost tenfold increase on the $125,079 in fines from the camera a year earlier.
According to the Centre for Road Safety for the first months after the speed limit drop people caught by the camera received a warning letter rather than a fine.

This financial year, while the fines have dropped they are still substantially higher than pre-2017 levels.
For the financial year to April this year, there was $676,656 in fines issued - $578,892 of those were for speeding fines.
That's a 50 per cent drop on last year's million-dollar amount but still more than three times higher than before the speed limit fell.
These figures suggest that, after two years some motorists are still not aware the speed limit has fallen by 10km/h.
The Centre for Road Safety pointed out the fall in the speed limit has had an impact on crash statistics along Windang Road.
In the five years to September 2016 there were 42 crashes along this section of Windang Road.
In the 18 months after the speed zone change, just three crashes were recorded.
"Our research shows that where there are red-light speed cameras fatalities have fallen by more than half and serious injuries by more than a third," said Centre for Road Safety executive director Bernard Carlon.
"We also find 99 per cent of drivers and riders that pass speed cameras are not fined and this compliance helps to reduce trauma on our roads."
