A cliff collapse at Bronte Beach has damaged infrastructure and closed parts of the beach and walking paths, narrowly missing beachgoers.
Incident and Immediate Response
Around midday on Friday, 1 August 2025, a section of sandstone about 20 metres long and six metres deep gave way at the northern end of Bronte Beach in Sydney’s eastern suburbs. Large rocks fell onto a stormwater drain and damaged a safety rail. The collapse occurred beneath a headland access point used by surfers and beach visitors.
Waverley authorities, staff, and lifeguards sealed off sections of the beach, the headland footpath, and the park above. Parts of the walking path and a small portion of the beach remain closed while assessments continue.

Narrow Miss for Surfers and Lifeguards
Several people were in the immediate area at the time but avoided injury. One surfer had stepped off the stairs moments before the collapse, while others were approaching the same spot. A lifeguard was reportedly about to descend the stairs when the rocks fell. Witnesses described a loud crack and ground movement as the cliff gave way.
Possible Cause and Expert Insight
Waverley authorities have indicated that recent heavy rainfall may have contributed to the instability of the cliff, which sits above a stormwater culvert. The damaged culvert and surrounding area are subject to a geotechnical assessment to determine stability and whether closures should be extended.
Professor Ana Vila Concejo, a coastal geomorphology expert from the University of Sydney, said rockfalls are a natural process for sandstone cliffs, which can fracture over time due to wave action.
Community Reaction
Local residents expressed concern about safety and the risk of similar incidents in surrounding coastal areas. Some noted they had recently walked the now-damaged stairs and stormwater pipe. Others said that on a busy, dry day, the outcome could have been far worse.
Next Steps
The authorities’ investigation will continue, with further safety measures to be considered once the geotechnical assessment is complete. Authorities are urging the public to avoid the affected areas until they are deemed safe.
