.. but only for a while
The 07/25 rwy at SYD will close in April 2008 to enable the construction of enhanced runoff areas at the Western end.
This will increase the usage of the 16/34 runways and may lead to some delays or diversions in extreme wind situations.

Based on the article, the extra safety zone will assist in the deceleration of the aircraft. Does this mean that it is actually an arrest bed made of collapse-able concrete?
Not being familiar with this airport, is this the favored runway for aircraft movement? I noticed that they have 2 N/S runways and they are putting a disclaimer stating that there will be an increase of aircraft movements and noise for those living in the flight path of the N/S runways...but considering they have 2 N/S runways I am guessing the prevailing wind comes in off the water. Any input would be appreciated (I love learning about airports I haven't been to).

RWY 07/25 is, as Curmudgeon mentioned not the preferred runway but used regularly for "Noise sharing". It is used less often because strong winds require it.
Not sure if the proposed extension, or the 5 completed so far, include collapsible concrete( I know the experts will chime in soon with the technical term) I have not seen the plan in that much detail. It may just be an extended braking area.
Curmudgeon, Collapsible concrete is like a high tech gravel or sand trap. A soft base, sometimes blocks or sheets of a styrofoam like material covered by a thin layer of concrete. The concrete protects the "arrestor bed" and allows normal actvities, even driving etc but when an aircraft overruns, the weight penetrates the concrete and the foam acts like a sandtrap bringing the aircraft to gentler halt.*
*gentler halt is relative in this case being less painful than ending up in the Cooks River

My understanding of this, is that it will basically be a pier like structure, long enough to meet current regulations for runway overrun areas. At present, unless you just get off the end of RWY 25, anything at a moderate speed would end up in the Cooks River.
As the article mentions there is also, a main sewerage pipe and a road tunnel (on the river bed) at the end of the runway. The construction will be a major undertaking and personally I reckon that they should do it all the way across the river with an associated taxiway, of course that would actually be a runway extension and require an E.I.S. !!
For normal day to day operations this will not be a big deal. The normal noise sharing practices will not be in operation the days the runway is not available, which will increase noise mainly to the north of the airport, the only real problem will be when there are strong westerlies, which is normally around September and October.
