Expert Arborist Reports Across Mosman Council

Covering Mosman, Balmoral, Clifton Gardens, Beauty Point and The Spit.

Mosman is defined by heritage homes, harbour-side properties and some of the most significant urban tree canopy on the Lower North Shore. Renovations, luxury home redevelopment and construction near retained trees mean DA Arborist Reports are commonly required alongside tree removal and safety assessments.

Suburbs We Service throughout Mosman Council

Mosman

  • Mosman

Mosman is characterised by heritage homes, established tree-lined streets, harbour-side properties and significant canopy trees. Renovations, luxury home redevelopment and construction near retained trees commonly require Arborist Reports, Arboricultural Impact Assessments and Tree Protection Plans.

Balmoral & Clifton Gardens

  • Balmoral
  • Clifton Gardens

Balmoral and Clifton Gardens include waterfront homes, bushland reserves and environmentally sensitive foreshore areas. Development Applications, tree removal proposals and building works near mature trees frequently require Council-ready arboricultural assessments.

Beauty Point & The Spit

  • Beauty Point
  • The Spit

Beauty Point and The Spit contain established residential properties, waterfront development and land adjoining Sydney Harbour bushland. Arborist Reports are commonly required for Development Applications, construction compliance and the management of protected trees.

Mosman Tree Preservation Rules

Most trees in Mosman are protected under the State Environmental Planning Policy (Biodiversity and Conservation) 2021 and managed in accordance with Mosman Council's Urban Forest Management Policy. Council consent is generally required before removing, pruning or damaging a protected tree.

  • Council approval
    Generally required if a tree is 5 metres or more in height, has a trunk circumference of 450 mm or more measured 300 mm above ground level, is listed on the Urban Forest Management Register, or is 2 metres or more in height within a Heritage Conservation Area or forms part of a heritage item.
  • Applications
    A Tree Permit Application is required for most pruning and tree removal on private land. If a tree is protected by a Development Consent, changes generally require a Modification Application rather than a separate tree permit.
  • Heritage and significant trees
    Additional planning controls apply to trees within Heritage Conservation Areas, heritage items and those listed on the Urban Forest Management Register.
  • Exemptions
    Council lists exempt species including Rubber Tree (Ficus elastica), Privet, Umbrella Tree, Norfolk Island Hibiscus, Coral Tree, Cocos Palm, Citrus, Mulberry, Oleander, Willow and several other nominated species. Deadwood removal on private land in accordance with AS 4373 is also exempt.
  • Public trees
    All vegetation on Council land is protected and any pruning or removal requires Council approval.
  • Development and tree protection
    Where development affects retained trees, Council may require an Arborist Report, Arboricultural Impact Assessment, Tree Protection Plan prepared in accordance with AS 4970, and Project Arborist inspections during construction where required by the development consent.
  • Need help?
    We can determine whether your project requires a Tree Permit, Development Application or Arborist Report and prepare Council-ready documentation.

Understanding these requirements early can help avoid delays and ensure your project complies with Council's planning and tree protection controls.

Frequently Asked Questions

Is my tree exempt from Council approval?

Council lists exempt species including Rubber Tree (Ficus elastica), Privet, Umbrella Tree, Norfolk Island Hibiscus, Coral Tree, Cocos Palm, Citrus, Mulberry, Oleander, Willow and several other nominated species, along with deadwood removal in accordance with AS 4373. We can confirm exemption status before you proceed.

How soon can you attend for an urgent assessment?

Fast-track reporting is available for urgent and hazardous tree assessments, subject to availability.

Do I need Council approval to remove a tree?

In most cases, yes. Council approval is generally required if a tree is 5 metres or more in height, has a trunk circumference of 450 mm or more measured 300 mm above ground level, is listed on the Urban Forest Management Register, or is 2 metres or more in height within a Heritage Conservation Area or forming part of a heritage item.

Can I remove a tree already protected by a Development Consent?

Generally, no. If a tree is protected by a Development Consent, changes usually require a Modification Application rather than a separate tree permit.

Do the same rules apply to trees on Council land?

No. All vegetation on Council land is protected, and any pruning or removal requires separate Council approval regardless of private-land exemptions.

Do you prepare reports for builders, architects and developers?

Yes. We prepare DA Arborist Reports at design stage, Tree Protection Plans post-approval and Project Arborist inspections through construction for residential and commercial projects across Mosman.

Do I need an Arborist Report for a CDC?

Many Complying Development Certificate (CDC) projects affecting trees still require an arboricultural assessment demonstrating compliance with AS 4970 and the relevant planning controls.
