This is a hard one. The leaf tip shape points to Swainsona behriana, but the ratio of the length of the calyx teeth to the rest of the calyx is more suggestive of Swainsoa sericea. Both PlantNet and VicFlora keys split them on how the hairs are attached to the stems - S. behriana with hairs attached at the base or towards one end, and S. Sericea with hairs attached about the middle. Not something I can tell with a photo.
