Good to hear you are back online Spida, I've stayed at that spot too, although you are supposed to be self contained they do have a male and female flush toilet open over at the station as you know, a bit old but not too bad, although I wouldn't venture over there at night (ok, I did but with a torch, lol ).   

The Pinjarra Country Caravan Park about 3kms down the road towards Dwellingup is not too bad either, it is fenced off by an electric fence from the stock is it is owned by a working cattle farm.  Has a resident caretaker;

See;  http://turu.com.au/parks/wa/peel/pinjarrah-park-country-camping.aspx 

Just a note of caution, there is no warning sign the CP is coming up, the sign showing a caravan is right at the entry crossover (ditch either side) don't miss it as no good turn arounds further down the road if you do. 

This is not to be confused with the Pinjarra Caravan Park on Pinjarra road to Mandurah. 

Hard drive on laptop crashed so have had 3 days in Pinjarra. Luckily there is a shop here that could do the job and recover all my files etc!!!! Whew. AND all the passwords etc! Funny how lost one can be without a computer! Also good that the 'powers that be' have not asked me to move from the 24hour park behind the dump point. Have spent a lot of money in this little town and didn't feel like a CP as well! Will head back to Yanchep for a couple of days and make sure everything is back where I need it then make serious moves south and back east over the next 2 months.
