Anyway, my diabetes nurse & GP agree that the clinic dietitian isn't for me & they've given me some other names to check out. But the GP clearly thinks it's not very complicated overall: "Eat lots of vegetables, nuts & fish and a reasonable amount of fruit" (which is pretty close to what I do anyway).
Then when I say I'd like to find somebody who can give guidance on possible strategies for getting to remission or even reversal there's some eye-rolling. "I think a <6% target is too low; go for something between 6% and 7%". Which I think is really just a translation of the main guidelines here in Oz (<7% in general, maybe <6.5% if Metformin+lifestyle, following ADA guidelines I believe).
Which is fine; he's a good non-D-specialist GP. It'd be good to bump things up a level, however.
On diet in general, this is the best thing I've found so far:

... claims abound for the competitive merits of various diets relative to one another. Whereas such claims, particularly when attached to commercial interests, emphasize distinctions, the fundamentals of virtually all eating patterns associated with meaningful evidence of health benefit overlap substantially. There have been no rigorous, long-term studies comparing contenders for best diet laurels using methodology that precludes bias and confounding, and for many reasons such studies are unlikely. In the absence of such direct comparisons, claims for the established superiority of any one specific diet over others are exaggerated. The weight of evidence strongly supports a theme of healthful eating while allowing for variations on that theme. A diet of minimally processed foods close to nature, predominantly plants, is decisively associated with health promotion and disease prevention and is consistent with the salient components of seemingly distinct dietary approaches.
