An open question is do the transmission of business sections even apply to another jurisdiction?
Given the impending shortage, an adversarial play is to open the channel to offshoring as a method of control for any AU based group pilots (offshore to onshore type model). This looks like the "angle" to me. Get everything up and running, EBA signed off and then make NZ as a pseudo base with AU overnights.
Of course, under this model, generously LWOP would be offered to those who wished to take a JC command, by way of being a "suitable applicant" [read management prerogative playing Machiavelli]. Would there ever be another AU command offered again?
If this scenario actually did occur, the same thing could done to other agreements within the group, including LH.
Just musing...
