Your example of procedures at Canberra as against Williamtown is invalid.
At Canberra, an aircraft at Parliment House is well clear of the approach path from the south, whereas the coastal lane at Willy CROSSES the approach path for an aircraft to Runway 30 (assuming an instrument approach).
Apples with Apples Dick.
And I agree with posters above - your comments on senior military officers make you beneath contempt
(Ex Mil ATC - 2 tours at Williamtown)
(Edited to add Instrument in the approach brackets)
