Storm damage and fallen trees in Narrabeen
People first
If anyone is trapped or hurt, call 000. If a tree is on the house, blocking the driveway or looks set to fall on the property, call the NSW SES.
Wires down? Stay back
Ausgrid says to keep at least 8 metres, about 2 car lengths, from fallen wires and to report them. Treat any branch touching a line as live.
Leave hanging branches alone
The SES says not to try removing trees or branches after a storm. Keep everyone out from under split or hung-up limbs.
Photograph, then call the insurer
Take photos and video before anything is moved, and speak to your insurer before you pay anyone for clean-up work.
Then an arborist
Once it's safe, an arborist can take the damaged tree down in pieces and tell you whether what's left standing is sound.
Tree removal in Narrabeen: what's local
East coast lows
The Bureau of Meteorology says these storms bring damaging winds, heavy rain and big swells. Council says the June 2016 east coast low hit Collaroy-Narrabeen hard, with devastating beach erosion and significant impacts on private properties.
Water that can't get out
In that June 2016 storm, more than twice the monthly average rain fell in a day, and king tides and big surf blocked the lagoon entrance. Saturated ground loosens a tree's grip, so a lean that appears after heavy rain deserves a quick look.
Lagoon and wetland trees
Council's Narrabeen Ward list includes swamp mahogany, swamp she-oak, bangalay, coast banksia, Sydney red gum and cabbage tree palm. Around the lagoon's fringes grows Swamp Oak Floodplain Forest, an endangered community, and North Narrabeen has endangered freshwater wetland at Nareen Parade.
Crews in the street
Ausgrid's trimming program listed Narrabeen and Collaroy in both October and November 2026. Street trees under the wires are Ausgrid's to clear, not yours.
Tree removal in Narrabeen: good to know
Council protects threatened species, their habitat and endangered ecological communities, and says it won't approve removing healthy, stable trees. Near the lagoon, a swamp she-oak may be part of that endangered forest rather than a lone garden tree, so ask council before booking a removal.
Since NSW's 2026 changes, dead and dying protected trees need a permit too, and a tree can only come out as an imminent risk once council agrees in writing. An arborist's written assessment is what council needs to see.
Hiring an arborist in Narrabeen
After any big blow, we'd walk the yard once the wind drops and look for new leans, cracked soil on one side of a trunk and hung-up branches. Anything there gets an arborist's visit before the next storm, with photos sent to council if removal might be needed. A healthy tree that just looks battered usually only needs a prune.
