Point Samson a beautiful getaway

I have jst been down to Roebourne for work and was delighted to find that there was not a bed to be had for love nor money in Karratha for the night and had to stay at Point Samson just 13km from Roebourne. Walking along the gorgeous main beach I couldn't help but be in awe of the number of sea birds wheeling around and diving into the water. The water was literally boiling with schools of fish close to the surface. I just wondered- how long will this fishery last?
