It would be the same as for any development adjacent to the cables where they make landfall. It will improve beach access. Mentioned in a previous article (linked below) - the region hosts submarine cables, so it's part of the Northern Sydney Protection Zone. Furthermore they have facilitated an increase of erosion to adjacent beaches. There are three main types of seawalls: vertical, curved, and mound. there is no excuse for purchasing a property on the beach in the last 30 years let alone 5 without an inkling of understanding of the risks.

The co-founder of Ksubiis to launch a '70s surf-inspired hotel on New South Wales' Mid North Coast. Here's a screengrab from the website about the proposed breakwall extension: It seems that the main concern about the extension is the interruption of the natural flow of sand onto Mooloolaba beach and hence increased erosion risk. That's the most sensible thing I've read so far. Point being that the experiment is a gimmick as it would be quite easily modelled in a software program given all geometric surfaces and the regular wave pattern. In 2017, Gold Coast City Council funded, in conjunction with threatened property owners, an artificial reef offshore from Palm Beach. The group aims to raise awareness of the impact that the building sector can have while pointing out that more drastic measures need to be taken, as most countries do not include full building.

Here Willi. No more excuses for your terrible workmanship anymore. Building up during periods of low swell energy, while being transported into the surf zoneduring periods of high swell energy, acting as a buffer to the incoming surf. For Sydney its not just beach suburbs. Surely, private properties can be protected but public amenities will require huge ongoing costs to keep up with the public requirement (sand nourishment is the first thing that comes to mind).
