Canberra's most profitable speed camera collected more than $1.54 million in the past year.
New ACT government data shows the speed-red light camera at the intersection of Northbourne Avenue and Antill Street was responsible for catching 6408 drivers in the 12 months to March.
The only camera which collected more fines in the same period was a mid-block camera on the Barton Highway between Curran Drive and Gold Creek Road.
There, 6743 drivers were caught, raking in $1.51 million for territory coffers.
Another speed-red light camera, at the intersection of Northbourne Avenue and London Circuit, ranked third in revenue collection, pinging 4380 drivers with a revenue total of $1.12 million.
A further 5006 drivers were pinged on Hindmarsh Drive and Ball Street by a speed-red light camera which netted $1.1 million.
The fifth most profitable unit was the mid-block camera on the Barton Highway between Gungahlin Drive and Ellenborough Street, which collected $918,400 from 4212 drivers.
Released a day after ACT Auditor-General Maxine Cooper issued a damning report on the camera network, the figures show the five locations contributed more than half of the territory's total revenue from speed cameras in the past year.
In total, point-to-point and fixed speed cameras netted more than $11.48 million in fines, with 47,900 fines issued to drivers on ACT roads.
The four point-to-point cameras on Hindmarsh Drive and Athllon Drive generated 2349 infringement notices during the same period.
Those fines netted $545,559.
A separate review, commissioned by Attorney-General Simon Corbell before the Auditor-General's review was released, will consider the cameras' impact on crashes and speeding. Conducted by the University of NSW's Transport and Road Safety Research group, that study's findings are due to be presented to the government by the middle of the year. Dr Cooper's report slammed the ACT government's use of cameras, finding they did not contribute to a reduction in speeding.
She said the camera network suffered from poor reliability, escalating maintenance costs and too many rejected infringements.
Mr Corbell said on Friday that the speed camera network would not be switched off, despite its inability to change driver behaviour.
Successive ACT governments have argued that speed cameras operate to reduce speed on ACT roads and not collect revenue, but this week's report found budget proposals were the basis of their operation.
''I have spoken to the [Auditor-General] about that and she is not recommending that course of action,'' Mr Corbell told ABC Radio. He said the camera network may be effective but that more reliable data was needed.
