Eucalyptus & Gum Tree Removal: What to Know

Eucalyptus trees are iconic to the Australian landscape but can pose significant risks in residential settings. Here is what you need to know about gum tree removal in Sydney.

Common Eucalyptus Species in Sydney

Sydney Blue Gum (E. saligna)

Grows to 40+ metres. One of the tallest and most impressive eucalyptus species in Sydney. Often found on ridgelines and in urban parks. Generally protected under council TPOs due to its ecological significance and size.

Spotted Gum (Corymbia maculata)

Grows to 30+ metres. Recognisable by its smooth, mottled bark. Common in Sydney gardens and streetscapes. A hard, dense timber that is more costly to cut and dispose of than softer species.

Ironbark (E. sideroxylon, E. crebra)

Grows to 25+ metres. Extremely hard, dense timber with deeply furrowed bark. Among the most difficult and expensive eucalyptus species to remove due to timber density. Chainsaws wear faster on ironbark.

Scribbly Gum (E. haemastoma)

Grows to 15 metres. Named for the characteristic "scribble" marks on its bark caused by moth larvae. A smaller, lighter eucalyptus that is generally less expensive to remove than larger species.

Hazards Associated with Eucalyptus Trees

Sudden Limb Drop

Eucalyptus trees are prone to dropping large, heavy branches without warning, particularly during hot, still weather. This poses a serious risk to people, vehicles and structures underneath the canopy.

Bushfire Risk

Eucalyptus leaves contain volatile oils that make them highly flammable. In bushfire-prone areas of Sydney (many areas on the urban fringe), large eucalyptus trees close to homes are a significant fire risk. The 10/50 Vegetation Clearing Scheme may allow removal within 10 metres of a building.

Root Damage

Large eucalyptus trees have extensive root systems that can damage driveways, foundations, retaining walls, sewer lines and stormwater pipes. Roots can extend well beyond the canopy drip line.

Council Regulations for Gum Tree Removal

Most Sydney councils protect eucalyptus trees under their Tree Preservation Orders. You will typically need council approval to remove a gum tree if:

•The tree is above the height threshold (usually 3-5 metres depending on council)
•The trunk diameter exceeds the council threshold at chest height (usually 150-300 mm)
•The tree is a native species with ecological value

An arborist report is usually required to support the removal application. Valid reasons for approval include structural failure risk, significant property damage, or the tree being dead or dying.

Indicative Cost Range

Eucalyptus Size	Indicative Cost
Small (under 10 metres)	$800 - $2,000
Medium (10 - 20 metres)	$2,000 - $5,000
Large (20+ metres)	$5,000 - $15,000+

Frequently Asked Questions

Many eucalyptus species are protected under local council Tree Preservation Orders (TPOs). The level of protection varies by council and species. Native species like Sydney Blue Gum and Spotted Gum are generally protected, while some planted non-local eucalyptus may have fewer restrictions. Always check with your local council before removing any eucalyptus tree.

Removing a large eucalyptus tree (15-25+ metres) in Sydney typically costs between $3,000 and $15,000 or more. Eucalyptus trees are often tall, heavy hardwoods that require experienced climbing arborists or crane-assisted removal, especially in residential settings. The cost depends on height, trunk diameter, access and proximity to structures.

Eucalyptus trees can pose risks due to their tendency for sudden limb drop, particularly during hot, calm weather. They also shed bark and branches naturally, and many species are highly flammable in bushfire conditions. However, healthy, well-maintained eucalyptus trees are a valuable part of the landscape. Regular arborist assessments help manage risks.

Sudden limb drop (also called summer branch drop) is a phenomenon where apparently healthy eucalyptus branches fall without warning, often on still, hot days. The exact cause is debated, but it may relate to internal moisture stress. It is one of the main reasons homeowners seek arborist assessments and, in some cases, tree removal for gum trees near structures.

Yes, in many cases professional pruning can address safety concerns without full removal. Crown reduction, deadwooding and weight reduction pruning can significantly reduce the risk of limb drop. A qualified arborist can assess whether pruning is a viable alternative to removal for your specific tree.
