Hmmm Waterbung Gap, Kaw kaw Gap, Asaro South Gap - there was a road gap uphill of Waterbung but rarely used and I cant remember what it was called.
The 'Tapini ILS' didn't have tracks and distances you flew down the valley with your right wing tracking a walking track carved out of the side of the hill - When the valley turned right you turned left and landed - very visual 'procedure'.
Daulo Pass?
