Privacy is an important consideration for many Sydney homeowners. Neighbouring properties, overlooking windows, and compact blocks can leave backyards feeling exposed. Trees offer a natural alternative to fences and screening structures while adding greenery and character.
The best choice depends on available space, sunlight, soil, water requirements, maintenance, and the screening height you need.
This guide covers the best trees for Sydney backyards, including options for smaller gardens, fast-growing varieties, planting considerations, and common mistakes to avoid.
What to Consider When Choosing Privacy Trees for a Garden
Before choosing a privacy tree, consider:
- Mature height and width
- Growth rate
- Evergreen or deciduous growth
- Root behaviour and nearby structures
- Sunlight and soil conditions
- Water requirements
- Pruning and maintenance
- Sydney’s climate and growing conditions
A tree that suits one property may not suit another, particularly on compact blocks.

8 of the Best Privacy Trees for Sydney Backyards
1. Lilly Pilly
Lilly Pilly works well as a living screen along a backyard boundary. Its leaves stay green year-round, and you can choose a variety that suits your garden’s size. Keep up with pruning to stop it from getting too large.
2. Water Gum
Water Gum brings dense foliage and a natural appearance to a garden. It can provide good screening in Sydney backyards, provided there is enough room for it to grow. Some pruning will help manage its size.
3. Magnolia ‘Little Gem’
Magnolia ‘Little Gem’ is a good fit for smaller gardens. The glossy evergreen leaves offer privacy throughout the year, while its white flowers bring some extra colour and interest to the space.
4. Podocarpus
Podocarpus is useful along narrow boundaries as it grows upwards rather than outwards. The foliage stays green year-round, providing a steady screen from neighbouring properties. It may need trimming from time to time as it gets taller.
5. Tuckeroo
Tuckeroo is a native Australian tree with thick foliage that provides useful backyard screening. Birds can also benefit from the food and shelter it provides. Give it plenty of sunlight, suitable soil and enough space to grow.
6. Waterhousia
Waterhousia grows quickly and forms a thick canopy, providing privacy as the tree develops. It needs plenty of space around it, so larger backyards are usually a better fit. Pruning will also be part of its upkeep as it grows.
7. Callistemon (Bottlebrush)
Callistemon, commonly called Bottlebrush, adds colour and screening to a backyard. Its flowers attract local wildlife, and it grows well in sunny spots with suitable soil and drainage.
8. Photinia
Photinia has dense foliage and colourful new growth, making it a popular privacy plant. It responds well to pruning, which can help maintain a fuller screen where garden space is limited.

Evergreen vs Deciduous Trees for Privacy
If you need privacy year-round, look for an evergreen tree. Its leaves stay on the tree rather than dropping in winter. Deciduous trees lose their leaves, but that can be handy if you want extra winter sun in the backyard.
Consider how seasonal changes in sunlight will affect your garden before planting.
Best Privacy Trees for Small Sydney Backyards
Narrow-growing, compact evergreen varieties are often better suited to smaller Sydney blocks. Layered planting with trees, shrubs, and ground covers can create privacy without relying on a single oversized tree.
Always consider mature height and width rather than the plant’s current nursery size.
Best Fast-Growing Trees for Privacy
Fast-growing trees can establish screening sooner, but faster growth can also require more pruning and greater space. Growth rate should be considered alongside mature size, root behaviour and maintenance needs.
How Far Should Privacy Trees Be Planted From Fences and Structures?
Planting distances vary by species and should allow room for mature roots and branches. Consider fences, buildings, underground infrastructure and access for future pruning.
There is no single distance suitable for every privacy tree, so species-specific requirements should be checked before planting.
Privacy Trees vs Hedges: Which Is Better?
Privacy trees can provide height and a softer natural screen, while hedges create dense, controlled boundaries. Trees, hedges and shrubs can also be combined as layered screening.
The right option depends on the available space, the desired height, and how much maintenance you want to undertake.
How to Create a Natural Privacy Screen With Trees
Start by identifying the areas that need screening and checking the mature size of each tree. Choose species that work well together and consider staggered planting for better coverage. Trees can be combined with shrubs and ground covers to build a fuller screen. Plan for irrigation, pruning and ongoing maintenance from the start.
Common Mistakes When Planting Privacy Trees
Avoid:
- Choosing a tree that becomes too large
- Planting too close to fences or buildings
- Ignoring root growth
- Choosing deciduous trees when year-round screening is required
- Failing to consider neighbouring properties
- Underestimating pruning requirements
