IMHO based on the botanical publications sources, this photographed plant, foliage only, has features of both Stylidium montanum and Stylidium graminifolium .

I used the key under Stylidium in NatureMapr, and considered leaf shape, width, serrations and altitude; the site is at 830 m which doesn't seem high enough to be montane or subalpine

Yeah.
The leaves, pale green, nearly horizontal rosette arranged, with nearly flat laminas, suggest Stylidium montanum.
These leaves serrations all the way to their bottoms fit the description of Stylidium graminifolium, yet serrations in its leaves look quite different in the form of fine serrations .
Hence the serrations in this sighting's photographs approach the description as lobes, rather than fine serrations of Stylidium graminifolium .
And yet, more, Stylidium graminifolium in the strict sense, has leaves usually growing upright, closer to vertical and at more than 45ยบ angle from horizontal;
and the leaves have much narrower laminas up to ca. 2.5 mm wide,
with bi-furrowed surfaces .
I suggest, we see in action here, the mixing or introgression, of genes from both taxa .
