It turns out the whole rural oculist thing is more complicated than I thought.
Firstly I was wrong in thinking that oculist was the preferred term in the nineteenth century. Five minutes with Querypic showed that while that might have been the case in the early part of the nineteenth century, by some time around 1860, the preferred term was optician:

As well as pharmacists
(interestingly, while the pharmacist was doing the testing, the spectacles were being made up by Carter and Werner, a large wholesale optician in Ballarat)
and those who simply claimed to be spectacle makers
and not just in Australia – a search of Welsh Newspapers online reveals much the same story:
with spectaclemaker being the term used in the days before the medicalisation of sight testing. and the Federation of Spectacle Makers being the recognised trade body:
But basically anyone could claim to be an eye tester.
However, what is also interesting is the case of our Tasmanian pharmacist outsourcing the making of spectacles to a wholesale optician- it meant that the pharmacist need only do the sight test without having to develop any technical skill in spectacle making …
