Found two on a dry track, then went and walked up a usually dry creek bed, and there were many. I've included the ones with the double stems, though they were maybe 100 metres away.
You have actually included two species. Image 1 and 2 are of C. fuscata. The multi-flowered plant in image 3 is C. carnea. The number of flowers is a key feature in determining species. C. fuscata will always have one flower and C. carnea will often have multiple flowers. I will confirm based on the first two images.
If you would like you can report the carnea as a different sighting. It might be wise to remove image 3 from this sighting in case someone fails to read the comments and assumes the 3rd image is fuscata. But it's not anything to worry about.
