Damn, I only have 1 listed at the Twelve Apostles. This one was about 830 yards south of the Twelve Apostles Beauty Spot and was wedged VERY tightly between two sheds.
Can you be more specific on the impossible one? I know there is a bonus board if you just drive past the beached Arch, at least that’s how it looks on the map. But it’s actually on top of the arch and can easily be accessed by going off the main highway there and driving up to it. I stopped before hitting it to check out the XP of the arch-top board and it’s only a 5,000 XP.
