Sutherland Shire Council has announced a $4.2 million coastal management plan to address erosion at Cronulla Beach following a series of severe storms that stripped significant amounts of sand from the popular swimming spot earlier this year.

The plan, developed over 18 months in consultation with coastal engineers and the local community, aims to restore and protect the beach for future generations while maintaining its natural character.

The Scale of the Problem

Winter storms in June and July 2025 removed an estimated 15,000 cubic metres of sand from Cronulla Beach and adjacent areas. At its worst point, the beach lost up to 4 metres of width in some sections, exposing infrastructure and reducing the recreational area significantly.

“This wasn’t unprecedented, but it was severe,” explained council’s coastal engineer Dr. James Whitmore. “We’ve known for years that Cronulla faces erosion pressures. Climate change is intensifying storm patterns, and we need to act.”

What the Plan Includes

The council’s strategy involves multiple approaches:

Sand Nourishment

• 25,000 cubic metres of compatible sand to be sourced from offshore deposits
• Beach replenishment scheduled for March 2026, after summer season
• Ongoing monitoring to track sand movement

Dune Restoration

• Native vegetation planting along dune systems
• Improved fencing to prevent pedestrian damage to dunes
• Partnership with local Landcare groups for maintenance

Infrastructure Protection

• Buried rock seawall beneath sand at critical points
• Stormwater outlet modifications to reduce localised erosion
• Upgraded beach access paths to funnel foot traffic

Monitoring System

• New wave and sand monitoring equipment
• Quarterly drone surveys to track beach changes
• Early warning system for erosion events

Community Consultation

The plan emerged from extensive community engagement, with over 2,000 submissions received during the public comment period. While most residents supported action, opinions varied on methods.

“Some wanted hard engineering solutions like sea walls,” Whitmore noted. “Others wanted purely natural approaches. We’ve tried to balance both, prioritising solutions that work with natural coastal processes rather than against them.”

Local surf lifesaving clubs were closely consulted to ensure the beach remains safe for patrols and competitions. Cronulla Surf Life Saving Club president Mark Thomas expressed cautious optimism: “We’ve lost beach width that affects our competition areas. If this plan restores that while protecting the beach long-term, we support it.”

Funding and Timeline

The $4.2 million budget draws from multiple sources:

• Sutherland Shire Council: $2.5 million
• NSW Government Coastal Management Program: $1.2 million
• Federal Government Beach Restoration Fund: $500,000

Works will commence in February 2026, with major sand nourishment completed before the 2026 winter storm season. The full plan spans five years, with annual reviews and adaptations based on monitoring results.

What Residents Can Do

Council is encouraging residents to support the plan through simple actions:

• Stay on designated beach access paths
• Report erosion damage promptly via the council’s online portal
• Participate in dune care volunteer programs
• Avoid removing vegetation from dune areas

A community information session will be held at Cronulla RSL on November 5 at 7pm. Council staff and coastal engineers will present the plan details and answer questions.
