Not a species I know. It keyed easily to Wahlenbergia planiflora in bot Plantnet and Vicflora, so I am pretty sure of the ID. I am not sure of the subspecies, which I suspect is longipila, from the haity leaves and broad seed case, rather than planiflora, with hairless leaves and a narrow seed case. It is not clear from the text in Plantnet whether the seed case is in longipila is hairy or not. The common species with flowers with a short tube and long lobes is Wahlenbergia multicaulis, which has much smaller flowers and a narrow seed case.
Hi Betty I think, it is very hard to id the subspecies from the 2 photos - perhaps I would tend to subsp. planiflora based on shape of glabrous seed capsule. The ACT Census Vers 4.0 2017 lists only the subsp. planiflora.
