Warrilla Beach-
"Warrilla Beach is a curving, east-facing 2 km beach extending between Windang Island and the shallow inlet at Barrack Point. The northern half of the beach is backed by the entrance training wall then natural dunes, which have been stabilised to form a large park, with the Warrilla SLSC and a car park located toward the southern end. The southern half of the beach is backed by beachfront houses and a caravan park." (BeachSafe,.org)
Construction of Sea Wall at Warilla Beach-
Warilla Beach suffered from severe erosion from the mid 1940’s due to the effects of coastal processes. The beach erosion accelerated in the 1960’s and 1970’s due to major ocean storms. A sea wall was constructed in the 1960’s along the southern portion of the beach to halt further erosion and provide protection to the housing development behind the beach.
Issue: Removal of coastal sand dunes and vegetation has caused a net loss of sand from Warilla beach over many years.
Effects: Property along Warilla Beach is under threat of erosion. During big seas and high tides the sea wall can accelerate erosion.
Management: Construction of a rock seawall to protect houses undertaken by Shellharbour City Council.

Construction of a groyne at southern end of Warilla Beach-
Issue: At the southern of Warilla Beach is the mouth of Elliot Lake. A groyne was built in the 1960’s to reduce sand build up.
Effects: Elliot Lake needs to be kept open to ensure water quality with regular exchanges with each change of tide.
Management: Shellharbour Council received a grant funding offer of $75,000, under the Coastal Management Program of the Department of Natural Resources, to extend the existing rock groyne at Elliot Lake on the southern end of Warilla Beach
Sand nourishment of Warilla Beach Issue-
Issue: Warilla Beach has experienced erosion over many years.
Effects: Property and infrastructure are at risk.
Management: Shellharbour Council placed 200,000m3 of sand from the Lake Illawarra entrance along the southern portion of Warilla Beach to replenish the beach in front of the existing sea wall. To help stabilise the sand placed in this area and to reduce the potential for sand to bypass and cause shoaling of the entrance channel of Elliot Lake the groyne was extended by 20m
