Thanks for explaining the airstrip register, makes plenty of sense other than every operator having their own (and possibly different) information.
I believe a lot of the smaller strips were automatically closed when the new rules came in to effect about 10 years ago.
How small are the strips that would have been affected? It would seem like a poor decision to arbitrarily close strips because they are under X meters or some other arbitrary value if there's someone who can safely operate in and out of the strip.
