About the only improvement would be to indicate some direction, such as 50 metres north west of the control tower, and to give you these Google Map images of the vicinity with increasing zoom power:
Shep’s Mound is inside the rectangle at bottom right of this orientation view (with road "1" being the General Holmes Drive airport tunnel that runs east/west just south of the area of interest):
and in the left half of the next shot:
and the darker of the two cars is atop the actual 'mound' in this shot:
So that's giving it my best shot!
By the way, at the bottom left corner of the first pic is the fence area accessed from 'the Beach'. Usually Shep's Mound is the best location for morning shots with the easterly sun behind you and the Beach is best once the sun has moved around.
Hope it's helpful for those not familiar with the area.
