I believe you... I'm sure there are a lot of rules and guidelines on that link. Also I don't mean to single you out or Australian operators either; there are plenty of similar rules and guidelines in the US and many other countries.
Well yes there is a wide variation of how Australian operators work so you can't assume that those rules and guidelines are actually followed actually. I have had my card + log checked by one for a dive, most check cards the first time you use them + want a disclaimer signed and yet others haven't had a problem with me showing up two minutes before the boat has left for the first dive I've ever done with them, a wreck dive and not taking any of my info or asking me to do a disclaimer. Same goes with getting fills - have only been asked for my card at one or two stores, and never for nitrox. One thing that I have always had checked is hydro stamps + O2 clean sticker though
