Probably OK. Polygonum aviculare and Plogonum arenastrum both occur in the ACT and the differences, though fairly obvious in the hand, are not so easy in a photo. The Vicflora key is easier to use than Plantnet. It states that the in arenastrum, the leaves are more or less equal throughout, the largest leaves 5-20 mm long; and in aviculare, the leaves on the side stems are markedly smaller (often about half as long as) the main stems), the largest leaves 20-50 mm long. Please comment.

I worked through VicFlora and settled on aviculare over arenastrum because leaves on laterals were distinctly smaller. Actual leaf size was a bit small for aviculare, but several species on this sandbar were showing stunted and reduced growth.
