Oxalis species are difficult to ID even in the hand. Sightings of Oxalis need to include good photos of the whole plant, of the stem showing the hairs, and the stipules (outgrowths) at the bases of the leaf stalks. In some cases, a definite ID requires knowing whether the plant has a taproot or not, or bulbils that form underground or not. Not a good idea to check by pulling up the plant if you do not have a collecting permit from the relevant NSW department.

To identify the yellow-flowered Oxalis spp, you need to have almost every bit of the plant in hand!

I wouldn't disagree with any of that, and I almost never bother trying to key out Oxalis, after many frustrating hours at it. However, this one seems to have rather glaucous leaves and in the NSW Flora O. rubens is the only species described that way - "subglaucous" actually. Plus it is described as being on islands, beaches and dunes, which is not far from where this photo was taken. That said, I once sent off a somewhat glaucous specimen growing on dunes at Durras and it got ID'd as perennans, so I give up!
