Hi
@RobynV - fellow Australian here
I'm not sure where you are situated- I'm a bit outside Canberra. I'm part of a low carb group which has doctors and other medical professionals which are very interested in low carb diets not just for diabetes but for other things. One of those doctors may be able to recommend someone in your area that's interested in blood glucose issues generally. They may be much more willing to organise the appropriate tests.
Is that something that would interest you?
