This whole business with domestic and international AOC's is utter nonsense. Is the air different outside Australia, other laws of physics maybe? No, of course not....... then why the difference in AOC's?
It gives some interesting opportunities though.... the route from Melbourne to Perth could then be flown by any company holding a FAOC because the flight ventures out far over the southern ocean on the way to Perth to duck around headwinds in winter. If 12 NM off the coast is where the flight becomes international ..... well you get my point.
