After some help/advise on trip planning for the Perth and south east WA leg of our big lap around into South Oz. Currently on road along Ningaloo coastline.

Looking for a list of must do and must stay places. Would prefer camping but happy to do some caravan parks if we can even get in being school holidays and peak season. We're self sufficient in a well equipped Patrol and off road camper trailer with kids (don't need water, shower, toilet)

Any suggestions would be appreciated.
