nope, the road is closed, mining area, aboriginal place.

Well, you can.
Park at gate before it's private property.
Walk along fence line. You're doing nothing wrong.
You'll disappear following the fence line over a hill.
You'll see the back of the pinnacle from Mad Max 2 where Max watches the compound and the tracks still there from movie leading to it.

From there up to you.

Mad Maxwell and I have been planning a trip to the Pinnacles for years. When are you going?
