What all countries have deployed their P3s and P8s?
That would really be a heck of coordination for Aussies..
I doubt it. Both aircraft types are US Navy types and the OZ and NZ crew probably trained at US Navy facilities (we trained them decades ago on older P-3's).
They are also all operating from the same airfield, so are probably attending joint briefings and being briefed by the same folks.
They are also native English speakers (well, OZ, well, sure
) which helps.
I doubt they will have any trouble at all.
