My family are '$hi*' farmers from Werribee. Actually a very large percentage of them in the old days were employed by the MMBW as rabbit and fox trappers. This in the days of Mixo if you know what this is. If you're in Werribee and talk to any long time local I am sure they will know my last name.
For the uninitiated or people from afar the Werribee project is about spreading poo poo and wee wee onto paddocks and allowing the land to filter the water. The bonus is very fertile lands, green grass and many happy cows. You have probably eaten beef fed by grass that grew in your own poo

Point is the other half (my old mans side) of the family were fisherman that moored boats at Werribee South, Point Cook and Kirks Point. They have fished the area for years. Still do.
Two things spring to mind on this one.
- Witnessing Flourescent Orange sludge in the water near the outfall as a young child. Explained as over capacity discharge. This was over 20 years ago and i am sure more people now equals more poo. I don't keep up with the times on poo farms so I am sure things have also changed with capacity. I am not a scientist but I am sure flouro orange stuff near outfalls could be bad news.
- A group of Asians either dieing or becoming extremely ill by eating mussels and oysters from the rocks not far from the outfall. Once again, no scientist but if the water was clean why would you fall ill from this?
Wanker is displaying self naming tendencies here but I sure as poo would not paddle my SUP around that area.
