There's one on display at the Australian War Memorial, Canberra.

Different sides of objects tell different stories of aircraft at war. One side of the LW/AW radar – the sole surviving example in Australia – tells the story of the radar's development in Australia and how in 1945 Australia had one of the largest radar networks in the world extending as far as Borneo. But another side of the radar offers an insight into the technological details of how the equipment worked. A third side tells moving personal stories of the crews that manned and operated radars. These personal stories form the basis of the new gallery, focussing on all Australians who contributed to and participated in war.
There's an un-captioned photo on the page as well.
From that and my photos, it looks like the cases are grey, the fittings olive drab, or a similar green, and the array (possibly?) black. It also looks like the AWM example has a good deal of original paint. Happy to send you my shots if they're likely to be of use. Most sensible would be to contact the Museum. As they'll have conserved their example for display, there should be easily accessible records of the paint.
I wonder if they mean: "the sole surviving
[complete] example in Australia "
HTH, would be interested in hearing more, Buz.
