My own one, so you can see the whole thing rather than just the wins.
Done for 50 on Bourke Rd in Zetland. There's a 50 sign visible in the shot. That stretch has four different speed limits in about 700 metres.
I went back on a quiet afternoon and photographed the sign from where a driver actually sits. That's the only way to stand in the middle of the road safely — which is also the criticism I copped for it, fairly enough. Normally that road is full of cars sitting on top of the markings, which is the whole point.
I also asked them a simple question: how many fines actually get overturned on review? The answer, in writing, was that working it out would take about 35 hours and cost me over a thousand dollars.
Review is lodged. No outcome yet. I'll update this thread either way — including if I lose, because a forum where the owner only posts his wins is worthless.
