improve wave formation off the Prince Street seawall, Dredging Today reports.
The sea slug will be created from 45,000 cubic metres of sand dredged from the Hacking River to clear navigation channels.
In what is believed to be a first for a Sydney beach, the sand will be strategically placed about 250 metres offshore in up to eight metres of water to form a two-hectare rectangular mound.
And while the sandbank will break waves, it won’t break the bank, with construction to be carried out at no cost to Sutherland Shire Council.
The sea slug was designed by reef architect Andrew Pitt to influence the breaking patterns of waves along North Cronulla.
The decision to proceed comes after months of negotiation between the council, the dredging contractor McQuade Marine, the surfing community and the Bate Bay Sand Placement Committee, chaired by Leader chief photographer John Veage.
Previously, sand dredged from the Hacking River was dumped along the coast, Mr Veage said.
The committee believed that a strategically placed sand slug could be beneficial at North Cronulla.
