Dick,
I worked as a Tower Controller at Williamtown, Butterworth, Darwin and Amberley. At EACH location I controlled without "owning" the airspace to the Control Zone boundary. At Williamtown quite happily with aircraft going up the lane. As I stated, during part of my time at Willy, Tower controlled the lane..........
I even provided the combined Approach/Tower service from the Tower and let aircraft up and down the lane with aircraft in the circuit!!!
In my total of 5 years as a controller at Willy, I must have controlled almost a 1000 transits of the lane. I probably remember holding 2 or 3 due to Instrument approaches to Runway 30.
Oh - now it's the first control boundary step? (your answer to Ozbusdriver).
Can you please make up your mind?
Willy doesn't own to 25NM in every direction - stop generalising.........
My mind is only closed on one subject - that you are - well, Ive already told you..........a couple of times.............
