I don't think it's got the same poi's as Cagey's, but here's one for units using wav for spoken alerts. It has speed, red light, variable, bus lane and other safety camera locations [Only registered and activated users can see links. ].
EDIT: I've also pulled out the gpx info from Cagey's AUSCAMS 1-FEB-12.gpi and repackaged it as AUSCAMS_wav_1-FEB-2012.gpi with a WAV alert "Warning, safety camera ahead".. Seems to work ok with the known cameras around my area.. but it could be dodgy because of the reverse engineering, so use with caution or test it first in simulation.[Only registered and activated users can see links. ].
