Moving on to Derby on the WA North Wet Coast,not a very interesting place, little going for it. Extremely tidal (11 metre tides) and mostly mud and mangroves. Sound familiar.
A few Pics.

 Apparently one has to hug a Boab tree. Go on ask me why.

 The longest wstering trough.

 Frosty's  Pool put  in by some diggers during WW2 as somewhere to cool off.
