MOTORISTS are still not getting the message about slowing down.
Three speed cameras in St Marys collected almost $700,000 in fines last year, according to the Office of State Revenue.
A camera at the corner of the Great Western Highway and Charles Hackett Drive raised the most revenue, almost $404,000.
A camera installed on the corner of Mamre Road and Saddington Street in October collected almost $105,000 in its first two months.
A third camera on the Great Western Highway near Pages Road collected almost $185,000.
Opposition spokesman for roads Walt Second and Labor candidate for Londonderry Prue Car called on the government to improve signage and to move existing warning signs.
"The signage at the Charles Hackett drive and the Great Western Highway can be improved," Mrs Car said.
"There is a case to move them further down the street so that motorists can reduce their speed— which is what everyone wants.
"We want them to reduce their speed."
Mr Second accused the government of using speed cameras as de facto cash registers.
"We support cameras as a way to detect overdue speed and make our roads safer, especially around schools, but not as a form of revenue raising," he said.
The highest amount of fines was collected in November, when $11.6 million was collected statewide.
Mulgoa MP Tanya Davies said signage at speed camera locations were improved with the size of the signs doubled and the cameras being part of the 2012 NSW Speed Camera Strategy.
"Roads and Maritime staff have informed me that they inspected the signage at the sites in November and found them appropriate and that they will continue to monitor safety at the location to ensure the safety of all road users," Mrs Davies said.
