Manton River Rest Area (Temporarily closed) - NT

The place description currently says this is a "no camping" area. If that is referring to the area just off the highway, I wonder when camping was banned? I ended up spending a night here on 12 May 2018. I was driving south from Darwin, and this was as far as I could get before dark. There were numerous people camping in everything from tents to caravans. Definitely not a pleasant camp site, as it's only meters from the Stuart Highway and road trains rumbled by occasionally throughout the night. Maybe camping was banned then too, and everyone was ignoring that fact. :)
