The Discovery at Era Beach and Immediate Beach Closures
Early on the morning of April 25, 2026, surf lifesavers patrolling Sydney's Royal National Park spotted a large whale carcass washed up on a rocky platform at the southern end of Era Beach. The animal, heavily decomposed after likely spending time decaying at sea, immediately raised alarms due to its potential to attract sharks. Within hours, authorities closed four popular beaches in the area: Garie Beach, Wattamolla Beach, Era Beach, and Burning Palms Beach. These closures came as reports of significant shark activity flooded in, with large sharks sighted swimming close to shore and around the carcass.
Royal National Park, located about 50 kilometers south of Sydney's central business district, is a cherished destination for surfers, hikers, and families, especially during long weekends like this one in late April. The timing couldn't have been worse, coinciding with heightened visitor numbers eager to enjoy the autumn sun and waves. Surf Life Saving New South Wales (SLSNSW) quickly deployed drones and jet skis for surveillance, issuing urgent warnings via social media and the SharkSmart app to keep people out of the water.
The decision to shut the beaches was precautionary but firm. As SLSNSW CEO Stephen Pearce explained, the presence of the carcass creates a feeding hotspot that draws in opportunistic predators. "The lifesavers are reporting a significant amount of sharks visibly off the beach and around the rock platform," Pearce said. "Our warning is, 'Don't go in the water'. We can't prevent people from going in, but knowing just how many sharks are there and the reports of larger white and bull sharks in the water, they're not the fish you want to be swimming in the same water with."
Understanding the Shark Threat
Shark activity around decomposing whale carcasses is a well-documented phenomenon in coastal Australia. The carcass releases blood, oils, and organic matter into the water, creating a chum-like effect that lures sharks from kilometers away. In this case, sightings included large great white sharks and bull sharks, both known for their presence in New South Wales waters during this season.
Bull sharks, in particular, are notorious for venturing into shallower coastal areas and estuaries, especially after heavy rains that flush nutrients and baitfish into the surf zone. Great whites, more offshore dwellers, are drawn in by large food sources like whales. The combination poses a heightened risk for swimmers, surfers, and divers in the vicinity. Historical data from the NSW Department of Primary Industries (DPI) shows that murky waters post-rain or around carcasses amplify encounters, as reduced visibility makes it harder for sharks to distinguish prey.
While shark attacks remain rare—Australia records around 20 bites annually nationwide, with fewer than three fatalities—the presence of multiple large sharks elevates the odds. In Royal National Park's remote Figure 8 Pools area, access is via bushwalks, complicating evacuations if needed.
The Whale: Species, Size, and Possible Cause of Death
Details on the whale remain preliminary as experts have not yet conducted a full necropsy due to its advanced decomposition and rocky location. Appearing large—estimated at least 10-15 meters based on visual reports—it is likely a humpback whale (Megaptera novaeangliae), common in Australian waters during their northward migration from Antarctic feeding grounds to breeding areas in Queensland. April marks the early phase of this annual journey, with thousands passing the east coast.
Australian whale strandings have increased in recent years, with over 100 entanglements reported in NSW alone since 2024. Causes include vessel strikes, fishing gear entanglement, acoustic trauma from sonar, and disease. The 2025-26 season has seen heightened reports, partly attributed to recovering populations post-commercial whaling bans. Conservation groups like the NSW National Parks and Wildlife Service (NPWS) monitor strandings via the Whale and Dolphin Strandings Hotline, but remote sites like Era Beach pose logistical challenges for response teams.
Authorities Mobilize: Patrols, Technology, and Alerts
SLSNSW ramped up operations immediately, using aerial drones equipped with cameras to scan for sharks up to 2 kilometers offshore. Jet skis with spotters patrolled the perimeter, while the SharkSmart app pushed real-time alerts to users' phones. NPWS rangers restricted bush track access to the beaches, posting signs and coordinating with local councils.
NSW's shark mitigation program, bolstered by $30 million in funding this summer, includes 37 acoustic listening stations and 305 SMART drumlines statewide. Though not deployed at RNP (nets are seasonal and whale-sensitive), the tech proved vital here. DPI shark scientists monitored tagged animals, noting bull shark movements post-recent rains.
The closures are set for at least 24 hours, with extensions possible until the carcass is addressed. NPWS is assessing removal options: towing offshore (risky with sharks/decomposition), blasting, or heavy machinery burial—complicated by the rocky terrain and environmental protections in the park. ABC News reports highlight the coordinated effort between agencies.

A Pattern of Past Incidents: Lessons from History
This isn't the first time a whale carcass has disrupted Sydney's beaches. In September 2020 at Bulli Beach (near Wollongong), sharks feasted on a humpback, closing beaches for days. Bondi Beach shut in 2018 after a shark-bitten whale calf washed up. Newport Beach closed for a week in 2011 due to a 10-meter sperm whale.
Further south, Tasmania relocated a swim event in April 2026 over a rotting sperm whale. Nationally, strandings peak May-November, with 2025 seeing record entanglements (nearly 100 in NSW). These events underscore the dual nature of whale recovery: more animals mean more carcasses, amplifying shark risks during migration.
Stats from Taronga Zoo's Shark Incident Database show 465 bites in NSW over 235 years, but recent upticks correlate with population growth and ocean use. Fatalities remain low (average 2.8/year nationally).
Community and Tourism Impacts
For locals in the Illawarra and Sydney southern suburbs, the closures disrupt routines. Surfers miss prime autumn swells at Garie and Era, known for consistent waves. Hikers on the famous Coast Track can't access Figure 8 Pools, a bucket-list spot drawing thousands weekly.
Tourism takes a hit during school holidays' tail end. Operators report cancellations for guided walks and kayaking. Economically minor compared to peak summer, but highlights vulnerability in eco-tourism reliant on safe access. Social media buzz amplifies: posts of the carcass went viral, mixing awe with frustration.
Conservationists view it positively—whales signal healthy oceans—but urge better necropsy protocols for strandings data.
Whale Migration: Why Now?
Australia hosts the world's longest mammalian migration: humpbacks travel 10,000+ km round-trip. Peak northbound sightings May-July off NSW, but early arrivals/deaths occur. Climate shifts may alter patterns, increasing strandings via stronger storms or shifted prey.
2026 season projections: 40,000+ humpbacks past east coast, up from pre-whaling lows. Entanglements rose with krill fishery growth; crab pot gear common culprit. NSW's response includes seasonal net removal (September-May) to protect whales.
NSW Shark Safety: Tech and Strategies
NSW leads with proactive measures: SharkSmart app (430k+ downloads), drone fleet (spotting 80% threats early), tagged monitors tracking 100+ sharks. Drumlines bait non-lethally relocate great whites/tigers/bulls.
- Drones: Cover 10km radius, AI-enhanced.
- Listening stations: Real-time pings from tagged sharks.
- Patrols: 24/7 during alerts.
- Public education: Avoid dawn/dusk, murky water, bait schools.
Effectiveness: Bites down despite rising visits (17m coastal annually). RNP lacks nets due to ecology, relying on alerts.

Carcass Removal Challenges and Plans
Removing the Era carcass is tricky: rocky perch prevents easy towing; blasting risks park habitat. Options include excavators via helicopter (costly), waiting decomposition (weeks, prolonged risk), or offshore sink (scavenger magnet).
NPWS prioritizes safety/environment; past ops towed via barges or buried. Updates expected soon; monitoring continues.News.com.au details the logistics.
Safety Tips and Looking Ahead
Until resolved:
- Check SharkSmart app before water entry.
- Avoid swimming near rivers post-rain or known carcasses.
- Surf between flags with lifeguards.
- Report sightings: 000 or hotline.
As migration ramps, expect more strandings. Long-term: better vessel tracking, gear redesigns. This incident reminds coastal dwellers of nature's balance—majestic whales sustain ecosystems, but demand vigilance.
Beaches may reopen soon if sharks disperse; stay tuned to official channels for updates.
