The way in is a little tricky, the road in is sealed. The site looks like it has been forgotten. There is no sign on the main road to direct you. Just keep an eye out for the tall antenna. There is an old entry from the main road or look for the slip lane running parallel.
This was a water collection area, you can see the water channel walls all around. If you walk up to the antenna you can then follow the channel’s down to a old forgotten dam. It’s beautiful in the spring time with lots of wildflowers about..
the cache you are looking for is a silver 300ml cylinder
happy hunting 😀
