Transport for NSW installed red-light speed cameras at two Great Western Highway locations - the intersection of Durham and Bentinck streets and intersection of Stewart and Keppel streets - in late April but gave drivers a grace period before they started issuing fines in late June.

Since late June, the camera at the Durham Street intersection has caught out 1213 speeding drivers and another 191 who went through a red light.

In Stewart Street, a further 304 speeding drivers received tickets along with 58 drivers who ran a red light.

The offending drivers have been fined a combined $374,819.

Member for Bathurst and Minister for Regional Transport and Roads, Paul Toole said he had little sympathy for motorists doing the wrong thing, saying there was no excuse for drivers to be speeding, or running red lights.
