8 Quickest Growing Trees for Privacy in Perth (2026 Guide)

You look out your kitchen window and there it is. The new two-storey build next door, complete with an upper balcony that now looks straight into your patio, pool, or back lawn. What used to feel private suddenly feels exposed, and in plenty of Perth suburbs that change happens fast.

That’s usually when homeowners start searching for the quickest growing trees for privacy. Fair enough. A living screen softens a fence line, cuts sightlines, helps with wind, and looks far better than a blank wall in most gardens. But speed on its own is a bad buying test. In Perth, a tree that grows fast in a catalogue can also turn into a high-water, high-pruning, high-risk problem once summer bites and the block starts feeling smaller than it did on paper.

The local reality matters. Sandy soils, hot dry summers, coastal wind, narrow side setbacks, overhead lines, and neighbour expectations all change what works. Some species shoot up and give great cover. Some grow quickly, then become maintenance hogs. Some look ideal in overseas guides but struggle here long term. If you’re weighing trees against physical privacy screens, the right plant choice usually comes down to how much room you have, how formal you want the result to look, and how much pruning you’re prepared to keep up with.

This guide keeps it practical. No generic nursery-tag advice. Just the species Perth property owners most often consider for screening, plus the trade-offs that matter on real blocks in places like Scarborough, Woodvale, Floreat, Bassendean, and Victoria Park.

1. Leyland Cypress (Cupressocyparis leylandii)

A neighbour builds up, second-storey windows arrive, and suddenly the back fence stops doing its job. Leyland Cypress is often the first tree people ask for in that situation because it grows quickly and gives height faster than many other screening options. Under good conditions, it can put on up to 4 feet (1.2 metres) a year, according to Davey’s guide to fast-growing privacy trees.

On the right block, that speed is useful. On the wrong block, it creates a pruning job that keeps getting bigger.

Where it works best

Leyland Cypress suits larger Perth properties where there is genuine room off the boundary and enough access to maintain both sides. It makes the most sense on wide rear fences, acreage-style suburban lots, or exposed sites where the owner wants privacy and some wind filtering from the same planting.

Its long-term size is the critical factor. This species can reach 60 to 70 feet (18 to 21 metres) over time, so a row that looks neat in nursery pots can become far too broad for a standard suburban side setback if it is planted without a plan. Spacing around 6 to 8 feet apart is commonly used for screening, and with decent establishment care, that can fill in fairly quickly.

Practical rule: Keep it well clear of fences, eaves, sheds, and overhead services from day one. Correcting a bad Leyland placement later usually means hard pruning or full removal.

What Perth homeowners often get wrong

The biggest mistake is choosing it by growth rate alone. In Perth, I’d only recommend Leyland Cypress where the site can handle the mature width and where the owner is prepared to prune early and consistently. If you let it run for a few years and try to bring it back hard later, the result is usually poorer shape, higher cost, and a screen that never looks quite right again.

It also needs the basics to be right. Good drainage matters. Full sun helps. Airflow through the planting line matters more than many generic hedge guides admit, especially once the trees start thickening up.

A few points are worth checking before planting:

• Best fit: Large boundaries, taller rear screens, and blocks that need a quick evergreen barrier.

• Poor fit: Narrow side paths, small courtyards, and fence lines with little maintenance access.

• Setback reality: Give it enough room from the boundary that future pruning can be done without constant fence conflict or neighbour complaints.

• Council and services check: Before planting any tall screening tree, check for overhead powerlines, verge visibility issues, and local council guidance on boundary planting and verge works if the line runs near the front.

Leyland also has a design trade-off. It gives a classic dense green wall, but it is a heavier, more formal look than the softer screening styles many Perth homeowners now want around pools, limestone walls, and newer alfresco areas. If the brief is a slim, architectural screen for a compact block, this usually is not the cleanest fit.

From my experience and recent industry observations here in WA, Leyland cypress often ends up needing repeated pruning on windy sites, and plenty are removed earlier than owners expected because the upkeep stops making sense. That does not make it a poor tree. It makes it a tree that needs enough land, enough access, and an owner who understands the maintenance bill before planting.

2. Bamboo (Phyllostachys species)

Bamboo gets attention because it gives the look people want fast. Tall, dense, modern, and far softer visually than a hard fence extension. In contemporary Perth courtyards and side boundaries, it’s become a fashionable option because it pairs well with rendered walls, black steel, limestone, and minimalist planting palettes.

Here’s the visual style many homeowners are chasing:

The problem is that “bamboo” is not a single answer. In practice, the wrong variety can become a containment issue, a neighbour dispute, or a cleanup job. For privacy, some owners love the instant screen effect. Others regret planting it because they didn’t understand the spread behaviour or the maintenance involved in keeping it where it belongs.

Why people choose it

On a narrow lot, bamboo can solve a privacy problem that broad conifers can’t. It gives height without needing the same canopy width, and it works especially well where the goal is to soften a boundary near an alfresco, plunge pool, or upstairs overlooking issue.

It also suits design-led gardens. In Mount Lawley and inner-metro renovations, bamboo often turns up where the owner wants a resort feel rather than a traditional hedge line. The canes add movement, and the foliage reads lighter than a dense cypress wall.

The trade-off is containment

This isn’t a plant I’d ever recommend casually. If you choose a spreading type without proper control, you’re taking on a management problem from day one. Even with better-behaved forms, bamboo still needs attention to irrigation, thinning, and boundary discipline.

What usually makes the difference is whether the installation was planned properly:

• Barrier first: If the variety needs containment, install a proper root barrier before planting.

• Watering matters: New bamboo won’t look good if it’s left to fend for itself through establishment.

• Annual checks: Inspect edges and barrier lines before a small breach becomes a larger one.

• Council and neighbour common sense: Boundary planting that spreads beyond your line is asking for trouble.

Fast privacy is only useful if you can still control it three years later.

For homeowners comparing bamboo with more traditional screening trees, this short video helps show why people like the effect so much in the first place:

Bamboo can absolutely work. I’d just put it in the “specialist choice” category rather than the foolproof one. If your main priority is speed and style, it’s attractive. If your main priority is low fuss, there are safer options.

3. Italian Cypress (Cupressus sempervirens)

Italian Cypress is less about making a big green wall and more about creating elegant vertical screening. It’s one of the most recognisable shapes in outdoor design, and in Perth it suits the climate and architectural style better than many people expect.

For commercial and formal residential sites, it has real traction. Verified data supplied for this brief states Italian Cypress holds 40% market share in Perth commercial sites and is valued for its narrow columnar form of 3 to 5 metres wide and 20 to 30 metres high, with growth of 60 to 90 centimetres per year in local hot, dry conditions.

Best for narrow, formal spaces

This is the tree for properties where width is the limiting factor. Think side boundaries, entry statements, formal pools, driveways, or a boundary beside a neighbouring structure where a broad hedge would feel bulky. In Floreat, Wembley, and newer architect-designed homes, it’s fashionable because it looks clean and deliberate rather than shaggy.

It’s also one of the better options when owners want privacy without losing a crisp Mediterranean or modernist feel. A row of Italian Cypress doesn’t read like a suburban hedge. It reads like a design move.

What it does well, and what it doesn’t

Its strengths are shape, drought response, and neatness. Verified data for this article notes a 98% survival rate after drought conditions and practical planting at 2 metre spacing for a full privacy screen in 4 years. That makes it useful where owners want a more controlled and predictable outline than Leyland Cypress can offer.

Still, it won’t suit every privacy problem. If your goal is to block a broad upper-storey view across a wide backyard, the narrow form can mean you need more careful layout and patience. This tree screens vertically very well, but it doesn’t create the same thick visual mass as some broader species.

A few practical notes:

• Use it where space is tight: Near driveways, paths, and built form, narrow width is a major advantage.

• Avoid overwatering: Italian Cypress hates staying wet around the root zone.

• Prune for discipline, not hacking: Light shaping keeps the line clean. Heavy topping usually ruins the look.

• Think in rhythm: Even spacing is what makes this species look expensive.

For owners who want privacy and a polished front presentation before sale, Italian Cypress can do double duty. It screens, frames, and lifts the look of the property at the same time. Just don’t expect it to behave like a broad hedge. It’s a column, not a wall.

4. Photinia Red Tip (Photinia × fraseri 'Red Tip')

Photinia Red Tip is the one people choose when they want privacy but don’t want the planting to look purely functional. It gives a proper screen, but it also brings seasonal colour through that bright red flush of new growth. In a suburban garden, that can make the whole boundary feel less heavy.

It’s especially popular where owners want a hedge that sits between formal and relaxed. Not as severe as clipped conifers, not as loose as a native screen. In family backyards and strata boundaries, that middle-ground look is often exactly what works.

Why it suits real suburban gardens

Photinia responds well to pruning, fills in nicely, and can be kept at a scale that makes sense for ordinary residential blocks. That matters in Perth, where plenty of privacy jobs aren’t about creating a massive shelterbelt. They’re about softening a fence, screening a patio, or reducing overlooking from one side.

In places like Greenwood, Bassendean, and mixed-density suburbs, it works well because it doesn’t demand the same long-term space as the larger cypress options. It also looks good from the street, which is useful when the boundary planting is doing both privacy and presentation work.

The maintenance reality

The red growth that makes Photinia attractive is also part of why people need to prune it thoughtfully. If you never trim it, it can become patchy and leggy. If you overdo it at the wrong time, you can strip away the effect that made you choose it in the first place.

The simplest approach is usually best:

• Prune to encourage density: Light shaping promotes fresh growth and a fuller hedge.

• Keep airflow through the hedge: Crowded inner growth can invite disease pressure.

• Use mulch during establishment: That helps young plants through hot periods.

• Match the plant to the height needed: Photinia is better for mid-height privacy than very tall screening.

A good Photinia hedge looks intentional. A neglected one looks tired quickly.

For homeowners who want the quickest growing trees for privacy but don’t like the heavy conifer look, Photinia is a sensible compromise. It grows well, looks ornamental, and can be managed without turning the garden into a pruning marathon. It just needs steady, sensible upkeep rather than neglect followed by a hard cut-back.

5. Privet Hedge (Ligustrum species)

Privet is the old-school answer that still works, even if it’s not fashionable in every garden design. If you want a dense hedge and you’re prepared to prune it regularly, privet can give privacy quickly and at a scale that suits ordinary suburban blocks.

That’s why it still turns up in older Perth suburbs and on renovation projects where the owner wants a fast fill along a long fence line without waiting years for a broader tree row to bulk out. It’s practical more than glamorous.

Fast cover, but hands-on

Privet’s strength is response. It grows, thickens, and tolerates clipping well, which makes it useful where a crisp boundary hedge is the goal. On a block in Wembley, Victoria Park, or Mount Lawley, it can help restore privacy around patios and side setbacks without dominating the whole garden.

But this is not a plant for people who dislike maintenance. Privet rewards regular trimming. Skip that, and it can become messy fast.

A practical way to think about it is this:

• Best use: Medium-height privacy hedge where neat edges matter.

• Not ideal for: Owners wanting a plant-and-forget screen.

• Strong point: It recovers well from pruning and fills gaps reliably.

• Weak point: It can feel labour-heavy compared with tougher low-maintenance choices.

Where it fits in modern Perth gardens

Privet still has a place, particularly on modest budgets or sites where the owner wants quick enclosure and already accepts regular hedge trimming as part of the routine. It also suits traditional homes where a classic green hedge feels right architecturally.

If you’re comparing hedge options more broadly, Swift Trees Perth has a useful guide on the top hedging plants in Australia that helps frame where privet sits against other screen choices.

For sale preparation and rental presentation, privet can also be effective because it tidies a boundary quickly and gives a property that settled, enclosed look buyers tend to like. Just go in with open eyes. Fast screening and regular trimming usually come as a package with this one.

6. Westringia (Australian Rosemary)

If you want privacy without creating a future pruning monster, Westringia deserves serious attention. It isn’t the tallest or most dramatic option on this list, but it’s one of the smartest for Perth conditions and for owners who want a water-wise screen that still looks neat.

Local judgement matters more than overseas plant lists. The verified brief supplied for this article highlights that many non-native fast screen plants struggle in Perth’s long dry periods, while local alternatives such as Melaleuca linariifolia and Agonis flexuosa are often stronger long-term performers. Westringia belongs in that broader conversation about choosing species that fit Perth, not just species that grow fast somewhere else.

Why Perth owners keep coming back to it

Westringia works because it handles the climate, clips well, and suits a wide range of home styles. Coastal, modern, cottage, native, low-maintenance strata planting. It can slot into almost any of them. It also avoids the heavy visual mass of conifers, which is useful if you want privacy without making a small yard feel boxed in.

For a front setback, side path, or low-to-mid screen around an outdoor sitting area, it often makes more practical sense than chasing a giant fast-growing tree. In Scarborough or Duncraig especially, that tougher, lower-fuss profile is valuable.

The practical upside

This is the kind of plant I’d recommend to owners who want a screen they can live with, not just brag about in year two. Once established, it generally asks for less water and less intervention than thirstier or more disease-prone choices.

Its best qualities are straightforward:

• Climate fit: Better aligned with Perth conditions than many imported privacy plants.

• Manageable size: Easier to keep in scale on compact blocks.

• Clean look: Fine foliage gives a softer screen than broad glossy hedges.

• Low drama: It doesn’t usually create the same ongoing maintenance burden as bigger exotics.

If you’re leaning towards native and climate-sensible choices, Swift Trees Perth also has a guide to Australian tree species in Perth that’s worth reading alongside this list.

Westringia won’t solve every overlooking problem. If you need to block a second-storey balcony immediately, you may need something taller or a combined solution. But for everyday suburban privacy, it often ends up being the choice people are happiest with a few years down the track.

7. Elaeagnus (Thorny Elaeagnus)

Elaeagnus is the workhorse security screen. It’s not the prettiest option here, and that’s fine. Some jobs aren’t about style first. They’re about creating a dense, durable barrier along a fence line where you want privacy and a bit of deterrent value as well.

That thorny growth changes how the plant functions. For side boundaries, service areas, rear fences, and less visible perimeter lines, that can be useful. On family entertaining areas or narrow paths, it can be a nuisance. This is a species where placement matters more than with softer hedge plants.

Best for tough, functional screening

In commercial and utility-style settings, Elaeagnus earns its keep because it’s resilient and doesn’t need fussy treatment. It can work on rental properties, rural-fringe blocks, or older suburban lots where the owner wants a screen that can handle neglect better than a more ornamental hedge.

It’s also useful where people want lower-branch density to stay in place. Unlike some plants that open up underneath if they’re shaded or badly pruned, Elaeagnus can hold a more solid barrier when managed sensibly.

Put thorny screening where people shouldn’t be brushing past it every day.

The real compromise

The trade-off is obvious. Spines make it harder to prune, shape, and clean up. If the planting is close to bins, paths, air-conditioning units, or places where kids and pets run, the practical downside can outweigh the screening benefit.

That’s why I’d narrow its use to specific jobs:

• Good choice for: Security-minded perimeter screening and harder-use sites.

• Poor choice for: Tight entertaining zones and high-contact family spaces.

• Maintenance note: Light shaping is manageable. Hard renovation pruning is less pleasant.

• Design note: It’s more functional than refined, so pair it with cleaner hardscape if appearance matters.

For owners who only want a durable green barrier and don’t care about a highly manicured finish, Elaeagnus can do the job well. Just be honest about the user experience. A hedge that protects the boundary but constantly snags sleeves beside the clothesline is usually the wrong hedge in the wrong place.

8. Thuja Green Giant (Arborvitae)

Thuja ‘Green Giant’ is one of the strongest all-rounders on this list when the site suits it. It grows fast, stays evergreen, and builds a dense screen without the same reputation for constant drama that some other quick privacy trees carry.

For Perth conditions, the verified data supplied for this article describes it as a top fast-growing evergreen for privacy in the region, with documented growth rates of 3 to 5 feet (0.9 to 1.5 metres) per year and the ability to form 20 to 30 foot screens in 5 to 7 years, based on Gardenia’s fast-growing privacy tree guide.

Why it’s getting more attention

This plant makes sense for owners who want height and density but don’t necessarily want to gamble on a species with a heavier long-term maintenance reputation. Verified brief data also notes that in Perth trials, plantings at 5 to 6 feet spacing achieved full 90% opacity by year 3, which explains why strata managers and commercial property owners keep looking at it for quicker screening outcomes.

It’s also practical for exposed sites. The same verified data states it tolerates long drought periods, summer temperatures up to 40°C, and has low water needs once established in Perth conditions.

The fit is still important

Green Giant is not a tiny-yard tree. It may be more forgiving than some alternatives, but it still needs room, drainage, and a layout that respects mature size. Where owners go wrong is assuming “narrow when young” means “narrow forever.”

For best results, think beyond the first two years:

• Use it for height: This is best where upper-storey overlooking is the main issue.

• Respect spacing: Tight planting may look good quickly but can create avoidable problems later.

• Mulch and establish properly: Fast-growing trees still need a decent start.

• Prune lightly, early: Small structural corrections are easier than major future reductions.

For modern developments in growth suburbs, Green Giant often sits in the sweet spot between speed, density, and a fairly tidy appearance. If a homeowner tells me they want one of the quickest growing trees for privacy but also want a practical long-term screen, this is usually one of the first species worth discussing.

Your Green Screen Awaits Making the Right Choice with Expert Help

You plant for privacy after a neighbour adds a second-storey window, or after one Perth summer on a bare patio convinces you the block feels too exposed. The pressure is to fix it quickly. That is usually when people choose the wrong species.

Fast growth helps, but it is only one part of the decision. On Perth properties, I look first at mature width, water demand, root room, pruning access, crossover sightlines, overhead services, and the distance to fences, pools, and footings. Local council rules and frontage visibility requirements can also affect what works near boundaries and driveways, so a quick check before planting saves a lot of rework later.

The best choice depends on the job. Leyland Cypress and Thuja Green Giant suit bigger blocks where there is room to let them develop properly. Italian Cypress fits narrow side boundaries and more formal property design. Westringia suits owners who want a lower screen with less irrigation and less trimming once established. Photinia and Privet still have a place, but only if regular clipping is realistic. Bamboo can work, though containment and neighbour impact need to be handled properly from day one.

Maintenance is where the significant trade-offs show up.

A fast screen planted too tight can become a recurring pruning bill, a mess around gutters, or a dispute at the fence line. A narrow upright row can look sharp from the patio and still fail to block overlooking from a higher window. Security matters too. Thorny Elaeagnus gives a very different result from a soft clipped hedge, and that should be an intentional choice, not something you discover after planting.

Perth sites often ask one screen to do several jobs. It may need to hide a pool filter, soften a retaining wall, reduce wind, and still leave enough clearance for access down the side of the house. In those cases, plant selection, spacing, and setback matter more than the nursery label. Some homeowners also decide that planting alone will not solve the problem and compare trees with physical privacy screens for tighter spaces or instant cover.

That practical filter matters for strata managers, commercial sites, and owners preparing a home for sale or lease. A screen that is tidy, proportionate, and suited to the block improves usability and presentation. One that outgrows the space does the opposite.
