Just one speed camera accounted for more than a third of the fine revenue from all 17 fixed cameras over the last financial year.
That would be the moneyspinner that is the speed camera on the M1 Princes Motorway at Gywnneville.
Northbound motorists detected speeding by that camera had to cough up almost $2 million in fines.
The northbound camera brought in a whopping $1.93 million in fines - up 7 per cent on the 2017-18 financial year.
The figure accounted for 34 per cent of the $5.68 million in fines collected by the 17 red-light and speed cameras in the Illawarra.
The $1.93 million came in the form of 8177 fines, a jump of almost 200 on the same time last year.
The camera is located in an area where the speed limit drops from 90km/h to 80, and the ever-increasing number of fines show that motorists are still not slowing down when they see the lower speed limit.
There's another camera monitoring the speed of southbound drivers; by comparison just 448 fines were issued in that direction for a total of $106,270.
The camera in the No2 spot for revenue was the one on Windang Road.

Last financial year, that camera went past the million-dollar mark, recording an almost tenfold revenue increase.
However, in the 2018-19 financial year, revenue dropped to $817,825.
There was also a 39 per cent drop in the number of motorists caught - from 6634 to 4017.
Rounding out the top three was the red-light speed camera at the Gladstone Avenue-Princes Highway intersection in Wollongong with $551,936 in fines.
These cameras were also the top three revenue-raisers in the 2017-18 financial year as well.
Sitting just outside the big three was that speed camera outside The Illawarra Grammar School.
Motorists travelling south still struggle with staying within the speed limit while travelling down that hill.
In the last financial year, southbound drivers copped 1752 fines for a total of $451,805 in fines.
Northbound drivers travelling up the hill outside the school had a better time of it.
They chipped in around half that of the southbound side - $249,153.
At the other end of the list, the camera that brought in the least amount of money was the northbound camera at Springhill Road with just 423,819.
The second and third-last places were both taken by the camera on the Princes Highway at Bulli.
Northbound fines accounted for $48,605, while southbound finished third-last with $94,035.
