By world standards, Oz is not really a busy place and for example if our procedures/practices were introduced into the UK or USA the place would come to a standstill. Must be a message there somewhere.
Triadic,
Great to see that, now you are out in the big wide world, you have notice that ICAO/US/UK actually know what they are doing, and it all works, with about a tenth of the 'Standard Phrases" in the Australian AIP.
Where "communications" is the name of the game --- not "complying with procedures".
As to the question, why read back the QNH when it is on the ATIS ---
dead bodies is why!! --- as a result of accidents that created said dead bodies ---- ICAO made it a SARP, and despite considerable opposition here at the time, it was adopted.
Tootle pip!!
