I've spent hundreds of hours herping in the hills particularly around the mundaring area. A friend of mine has a large property in the national park, 1 of 4 I think. I've seen 10 - 15 carpetys in the area over the last 5 years. Have never seen one with any orange/yellow. Mostly black and white with different shades of gray. Not saying that some don't exist with that colour in the area, I have just never seen them.
