This is not one of the usual species of Goodenia in this area. It is important enough, if you are willing, to go back and get more photos of the leaves, the flower stalk, and the outside of the flower. If anyone has a collecting permit, it should go in to the herbarium for a proper ID. With a photo, too often it happens that even with detailed photos, the one piece of information needed for an ID is not there.
I can only think I was tired yesterday when I looked at these photos. It was obvious when I had a second look. As a general rule, with sightings, could you take photos of the whole plant, a flower from the top and side, and a whole leaf. In some plants, the bottom of the leaf is also important. Your main photo, of one flower, is stunning.
