There are about 3 sets of speed/redlight camera's on alexander parade, 3 in bound, 3 out bound. They've been there for at least 2 years now. The one on higtstreet road and springvale road is NOT a speed camera, it is an updated red light camera. There are 2 different sets of speed limits that intersect there, one is 60 the other 70. The way to tell for future refrence is look for a large cyclinder on a pole or the side of a camera, thats the radar.
There are far more that 4 in victoria, there's at least 2 where mountain hwy meets boronia road.
