My understanding is that a creche at a pool or gym would still need to adhere to the same standards and guidelines that other creches/childcare centres do - I know that the one I go to does and that the carers have to be trained and accredited. With this in mind most pools have swim instructors who are specifically trained to teach swimming to the disabled and the carers should be trained too. I think the Human Rights and Equal Opportunity Commission should be getting a letter from you about this - it is disgaceful, and I daresay illegal to discriminate at that level.
