What is it?

I found this oh so pretty little flower on our outing today. I am not up on my Oz flowers do have not a clue what it is. Any info would be gratefully received.

Today we ventured out towards the Blue Mountains in search of a bit of land that was a land grant given to my Great Great Great grandfather, Edward Smith Hall. We did find it which is now part of the University of Sydney Vet School. Pictures were taken and we pondered how on earth these pioneers ever managed to survive especially the women who had children in tow too. They must have been made of strong stuff.

My thanks to you all for continuing to stop by and view my shots.
