Yearly sand renourishment occurs to replenish sand lost to sand drift that has been exacerbated by development of the bay. Around 20,000 cubic metres of sand is transported annually to keep up with losses of around the same volume. Moving forward the council is looking into sand back-passing, potentially coordinated with a nearby dredging program, to make the renourishment more cost effective in the long term.
