Yes it does.
Australia only grants a very small amount of 457 Visa for Pilots, and does not have Pilot Skills on its ISSL either.
By the look of the submission NZ has also already granted a small amount of Visas on the basis of Pilot Skills too; can't fathom why!
The difference is, by adding Pilot Skills to the shortage list it makes it that much -easier- for Immigration to grant the Visas.
