You don't need a TG licence to own a dive shop. You don't even need a work permit to own it, just to work in it. You do however need a BTB Operator's Licence, and each of your boat captains needs a Captain's licence for the class of boat he drives.
I have dived many times with most dive shops in the area, and I do think most of the above criticisms do apply to many of those. Not all and not all of the time. My problem is that there's no effective regulatory framework to prevent them. But a huge problem lies in getting people to recognise that there are issues that need addressing, even with highly regarded operators. One demonstrated by the emotions surfacing in this thread.
