I presume this was bought. It has far too few stamens to be in the Hibbertia obtusifolia group. My initial thought is H. empetrifolia, the farthest west it gets being the eatern edge of the tablelands. If you really want to know what species it is, I need a photo of the centre of a flower clear enough so I can count the stamens and see if they are on one side of the carpels or all round them, and also count the carpels. Or field notes giving that information. That is for starters.
