As a charter operator I have to check to cover my arse.

Snipping your post can certainly start some scuttlebutt around here!
FWIW, you'll get some TDI deco procedures cards with 50m depth certifications on them, due to many of the Sydney wrecks being around the 48m mark.
For CCR cards my little collection reads...
TDI - MOD 1 (or air diluent) max depth 40m, max deco time 5min @ 6m.
SSI - Trimix - no further elaboration
IART - level III (trimix) - no further elaboration
I suspect you'd need to take a more holistic approach than is done way up north (have specific card or no dive). Having someone with a card based on PP of various gasses is going to make for a sliding rule of thumb. Besides a card, I could imagine wishing to check that the diver has:
- has a proper dive plan which in theory will work
- has a justifyable bailout plan
- has completed an appropriate checklist for assembly
- has done predive checks
- has paid in advance
Personally, I would have no qualms being asked these questions, especially if it was the first time on a particular boat. It may even reassure me the operator knows what they are on about!
