blackduckies that is very interesting and sound reasoning - I have not come across someone who waited for the reason you did, but what a lovely way of looking at your situation.

Ok so I have just heard back from Genetic Health Services Vic. The lovely genetic counsellor answered my questions very satisfactorily! She said that, while several of their practitioners (who may perform the CVS) are as experienced as Paul Shekleton, that they also have a significant number of practitioners who are certainly not - who are completing their training in this specialist area. Indeed, one of them may perform the CVS (supervised). And there is no way to control who will perform it.

So for me, that answered my question - and the genetic counsellor agreed that, for my own peace of mind, it sounded like going private with a known practitioner was a good option for me. I'm glad they called back, they are a great resource!
