Photos taken around 16 July 2006:

(Left to right) [1] An excellent shot of the eastern section of the lake entrance area with the northern breakwater works to the left. We can see that a great deal of sand needs to be removed once both the northern and southern breakwater works are complete. [2] The northern breakwater works are proceeding swiftly thanks to the experience of the LIA contractor Coast Wide Civil. [3] The rock 'wall' on the left is in fact an unstructured pile of basalt which will be used to complete the northern breakwater. The 'road' running up to the works cannot be entered by the public. [4] The Lake Illawarra Entrance Works project Stage-2 is a substantial undertaking. Sand dredged from the entrance once the northern and southern breakwaters are completed will be trucked down to replenish the southern end of Warilla Beach (the boulders top-right running up to the Little Lake entrance and Barrack Point.   

(Left to right) [1] We can see the only real 'deep' water at the lake entrance is that manufactured by the LIA next to the causeway at Reddall Reserve (next to the bottom car parks). The lagoon middle-right is an excellent venue for recreation and children, specifically designed by the LIA. [2] A good shot of the southern training wall, which breaks to allow flushing of the lagoon then re-starts with the intermediate breakwater. The walls will be extended to form the southern arm of the current breakwater works. [3] The southern training wall running up to Windang Island. Note how sand from Warilla Beach has already nearly covered much of the wall - one of the perennial problems facing the lake entrance. [4] The wave action constantly pushing sand into the lake entrance. Perkins Beach is the main culprit in this shot, but it depends on which way the swell and wind is running, for how long and how strong. 

(Left to right) [1] Right above the northern breakwater works. The project is making good time, with the new breakwaters jutting into the ocean and the monumental shift of sand highly likely to create excellent surfing conditions. [2] The four main machines being used by Coast Wide Civil on the initial northern breakwater. The very expensive and effective plant machinery is much larger than the photo illustrates. [3] The basalt rock stockpile which is being transformed into the northern breakwater. From a distance the 'wall' looks to be properly manufactured, but of course at this stage is just a pile of boulders and rock placed along the lake shore. [4] The basalt along the rock pile is quickly being re-laid through Perkins Beach. Yet again this shot is a good example of how shallow Lake Illawarra naturally is.
