How John's handles emergency tree services.
Keep people away from damaged branches and never approach a tree touching powerlines. Once immediate danger and electricity-network hazards have been reported to the right emergency service, call and explain what has happened and what is affected.
Across the Lower North Shore, detached homes, strata properties, compact sites and harbour-side blocks can each need a different access plan. The area has established native and ornamental trees across gardens, streets and bushland edges.
Urgent calls commonly involve fallen trees, broken or hanging limbs, storm damage and blocked driveways or access. After the immediate hazard is dealt with, branches, timber, stumps and remaining tree work can be discussed.
- Fallen trees
- Broken or hanging limbs
- Storm damage

What to check before the work starts.
Deal with immediate danger first. Once it is safe, keep any photos of the damage and check whether Mosman Municipal Council asks for a notification or other follow-up after urgent tree work.
- If there is an immediate danger, keep people clear and contact emergency services where necessary. Check the current Mosman Municipal Council process for urgent tree work when it is safe to do so.
- Keep people away from damaged branches and unstable trees.
- Stay clear of trees touching powerlines and call Ausgrid on 13 13 88.
- Tell us what has moved, what is affected and whether safe access is blocked.
