Without looking at the complexities of the ID features, I'd be very wary of calling this a Blue-breasted without extremely knowledgeable local opinion. Especially as it's likely to be the least common and most localised species in that general area.
Check out the link Larry......looks odds on to me?
Just too grey for Variegated

I wouldn't claim anything definite just from flicking through a range of supposedly correctly identified pics, when it comes to fairywrens.
Whilst under Blue-breasted, range is stated as 'Across Southern Australia'.

maybe, but I got the impression whilst in Aus that it was very patchily distributed. I've only seen it at one site, and I've spent more than a year in Aus in total. Whereas Variegated Fairywren is everywhere.
Would 'throughout mainland and Western' include the South, a bit vague?

If you're wondering about the range of Variegated, then it's far more widespread in South Australia than Blue-breasted.
The bill colour is different for many species but caution should be exercised in using this feature alone as the differences can be very subtle and dependent on the light conditions in which the birds are viewed. So while a female Variegated Fairy-wren generally has a far more orange-tan coloured bill than a Blue-breasted, which tends to be a richer, darker red, especially at the tip, this feature is not as reliable as comparing the relationship of the bill colour to the lores and eye-ring. The darker, chestnut lores of Variegated contrast strongly with its paler bill, whereas in Blue-breasted the lores are about the same colour as the bill.

It's worth noting the following from there:
The OP's bird shows obvious contrast between the darker lores and paler bill, which is good for Variegated.
