We have just had two nights at Kojonup in the RV site, across the road from the Information Centre.  Drinking water is available near the dump point, toilets and free bbqs are in park across the road.  Good level area, walking distance to shops, pubs, swimming pool, bowls club etc.  $5.00 per night.

Is in Camps book, but mine is in the 4wd, and it is dark outside : )

Thanks for the head up on that one.  I don't know how I missed it previously.  I spent one night in the free camp between Kojonup and Arthur River, picnic table and not much else but big area, more further in but watch the scratchy and overhaning branches for those, best to walk the track first..

Would that be Martup Pools?  We camped there last May, but I believe the mossies get bad

Not sure, the area is called Woodanalling on the map (on the main road though), no town there, big rest stop sign showing table and trees, I went a fair way in and didn't see any water (pools) only a couple of gravel pits. 

The front area is flat and wide and ok for big rigs, the picnic area is on the eastern side of the road.  May be in Camps, I'm not sure.
