Don, I read the same info from the same website; you either lazily copy/pasted some of the text or wrote it down verbatim.
At least you did some basic research this time instead of your normal cod-gob efforts, even though you drew your own conclusions.
The washed up baby wipes happened in 2011.
The Diamond Head/Vaucluse outfalls are slated for closure later this year, or didn't you know that either?
Nah, you haven't read enough - the latest incidents with baby wipes was only at Xmas time, that's why Coogee and Maroubra were closed then. Admittedly that only happens occasionally since the outfall was moved but it does still happen. I don't copy/paste - I read up about stuff and this happens to be something I've taken an interest in for some years just because the practice is so disgusting. Dirty old Sydney...
Vaucluse - who knows if that will actually close - it's just a matter of redirecting that wealthy suburb excreta into the main Eastern outfall at Maroubra - which will continue to pollute up and down that coastline when conditions are right. So really all they're doing is combining that outfall with the Eastern outfall and making that problem worse.
That the main eastern outfall still exists is still a ridiculous anathema in the 21st century - it was moved to 3.6km off-shore by the Carr government but the sheer amount of sewage being discharged (499 m/l a day @ 82 meters depth, which will be made worse as the population expands) means that the dissipation simply doesn't happen quickly enough. Remember that's only partly-treated - 'effluent'.
Surprisingly Melbourne is one place that gets it right - in fact Boags Rocks sewage outfall on the Mornington Peninsula (on the Bass Strait side) releases water treated to such a high standard that it contains no bacteria at all. That's thanks to the fact that Melbourne Water spent big $$$ at the Eastern Treatment Plant to get it right - why couldn't Sydney do the same?
