I can provide a link to a video of a reporter who interviewed locals who then took a trip out there. You can decide for yourself whether or not the old guy has the right spot but
I have seen the maps and it looks right to me, and it is my opinion that he, like Mr G and Mr C before him, has exactly zero ulterior motive to make up a bunch of inaccuracies or pretend knowledge.
If I could edit your map I would be able to point out exactly where the girls were allegedly located, in the bend of the river. The title number is obscured but it would be map reference I4 assuming your map is on a A-Z 1-10 grid. Right under the little pink dashes (bridge?) , on the 25 acreage where it abuts public land.

This video is long and somewhat tedious but it is worth watching IMO. It gives a great insight to the spot they were found therefore the mind of the person who chose such an unlikely type of place to attempt to -what - hide his crime? He could've buried them and they never would've been found, but he just dumped them out there like he didn't care if they were found or not.
The area also seems far more maintained than I expected, and with more traffic too (or maybe I'm just used to Aussie Outback roads
). It's not what it used to be but it's still fairly regularly used, the tracks are well worn and there are many cleared areas where picnic tables used to be.
Wierd. They were far more likely to be stumbled across than I had believed.
