I'm getting the impression, just from the few stories posted here, that discussing and completing the specific performance requirements for the AOW dives may not be a priority for some dive ops and/or instrctors.
For those that did their AOW in Coz as part of their dive package, I'm curious about the five dives that were used and the specific performance requirements that were completed. The PBB dive has quite a list. The Nav dive has very specific requirements. The Deep dive is certainly available in Coz... but it also has specific requirements to count toward AOW. Of course "Boat Dive" is a given in Coz, although using that as part of an AOW isn't exactly giving the customer much value. Drift, Fish ID, Night Dive? Again, there are specific requirements.
If you're looking to do AOW in Coz and you want to actually learn something (instead of just getting the card), it might be worth finding how how much effort a dive op is willing to put into the class (i.e. is "Boat Dive" one of your dives?) and how well they adhere to the specific performance requirements of the dives. A deep dive where they tell you "hey look... you're deep!" doesn't qualify.
