Mt McDonald above Cotter reservoir is 788m, cf. the Museum's 560m. 
But it's slightly south of west.

WNW at 19km is the hill above Uriarra Crossing, but it's only 622m.

NW at 19km is Surveyor's Hill at 788m, but there seem to be no 
convenient roads and anyway Black Mt's nearby 812m bulk should block 
it.

Odd.

(Although I can see that he'd have needed to stay away from existing 
installations, and hence the obvious nearby hills were all too 
awkward).

I don't want to be unduly sus about YLess4U.  (I don't know them, and 
I'd love these things to work).  But this doesn't seem to stack up, 
and, in accordance with Link Institute philosophy, I'm sceptical.

On the positive side:

The towns that they currently cover mostly look more tenable - 
although Michelago has an awkward low ridge in the middle, and I the 
Burra valley has a fold in it too:

And the slide set from last year looks pretty credible:
