We don't free camp so have no first hand experience & haven't been up that way for a decade or more.
BUT
My old copy of CAMPS 6 (think they're up to 8 or 9 now) shows several & some of them off the road & with toilets & some shade.
If you are intending to free camp that it might be wise to get a copy of CAMPS book & the App Wikicamps that only costs a few dollars. I have both but never used either except for interest.
Let me know if you want details of the camps in my book & I'll post them. But they'll be just on face value & perhaps no longer exist.
I'm sure that many others will have been that way recently & have lots of first hand info.
My post was just to recommend those two essential resources for serious free campers. There are several others like Badgers too.
There are 'free' camps alongside most roads, and there are 'freedom-of-choice / low cost camps' that are often surprisingly lovely
One of the latter we used 18 months back was the Keep River national park on the border of NT & WA ... there are 2 campsites, one near the road and the other some distance away from the road. The second site had the more spectatular scenery ... often called the mini bungle-bungles, and it was well worth the $7 per night fee
