At a Glance
Residential fencing in Perth typically costs $1,900–$9,500 per job. Sandy soils make post hole digging straightforward in most suburbs, but coastal areas with limestone subgrade and sloping blocks that need retaining walls before fencing can push costs higher.
What's Included in the Price
- Removal and disposal of the old fence (if applicable)
- Post holes dug and posts concreted in (deeper footings may be needed in sandy coastal soils)
- Rails, palings or panels installed and capped
- Gate installation (pedestrian or driveway, if specified)
- Compliance with AS 1684 Residential Timber-Framed Construction for structural requirements
Materials represent around half the total cost. Labour, concrete, and old fence disposal make up the rest.
What Affects the Cost
- Fence length. Perth's large suburban blocks mean longer fence runs than most east coast cities. A full perimeter fence on a standard 700m2 block is a substantial job.
- Timber species. Jarrah is locally sourced and popular for feature fences. Treated pine is the standard for boundaries. Hardwood posts with pine palings are a common mid-range option.
- Sand and limestone. Most of Perth sits on sandy soils, which are easy to dig but can require wider post footings to prevent leaning. Coastal suburbs with limestone subgrade (Scarborough, Hillarys, Mindarie) may need rock breaking for post holes.
- Retaining walls. Where ground levels differ between properties, a retaining wall is often needed before or in place of a standard fence. This is a separate job that adds significant cost.
- WA Dividing Fences Act. Like other states, WA requires neighbours to share the cost of a sufficient boundary fence. The process involves written notice and a 21-day response period.
- Gates. Perth homes commonly have both a pedestrian side gate and double driveway gates. Automated gates are an increasingly popular add-on.
A 20-metre treated pine paling fence on flat sandy ground with a pedestrian gate sits toward $1,900. A full-boundary jarrah fence on a sloping block with limestone drilling, retaining wall coordination, and automated driveway gates pushes toward $9,500.
Perth-Specific Considerations
Large blocks, long runs. Perth has some of the largest residential blocks of any Australian capital. Suburbs like Joondalup, Wanneroo, Baldivis, and Rockingham regularly feature 600–900m2 blocks, meaning full perimeter fencing can exceed 80 metres. When comparing quotes, make sure the per-metre rate is consistent across the full length.
Sandy soils. Most of Perth's metropolitan area sits on Bassendean or Spearwood sand. Post holes are quick to dig but posts can shift if footings are undersized. A good contractor will use larger-diameter concrete footings than they might in clay soil.
Limestone subgrade. In coastal suburbs from Scarborough through to Mindarie and down to Fremantle, limestone sits just below the sand. This can require rock-breaking equipment for post holes, which adds time and cost per post.
Retaining walls and level differences. Perth blocks often have significant level differences between properties, particularly in hillside suburbs like Kalamunda and Lesmurdie. If the ground drops more than 500mm at the boundary, a retaining wall is usually needed before the fence goes in. Retaining walls are a separate trade (often a landscaper or mason), so coordinate both quotes.
Dial Before You Dig. Call 1100 before any post holes. Gas, water, and telecom lines run along boundaries throughout Perth. This is free and should be completed for every fencing job.
Hiring a Licensed Carpenter in WA
In Western Australia, builder registration is managed by Building and Energy (DEMIRS). For fencing work that requires a building permit or is valued over $20,000, registration is required. For smaller fencing jobs, registration is not mandatory but using a registered contractor provides better consumer protection.
Ask for:
- Builder registration number (if applicable) or ABN and insurance details
- Proof of public liability insurance
- A written quote with per-metre pricing, timber species, and post spacing
- Confirmation that Dial Before You Dig has been completed
- Explanation of WA Dividing Fences Act notice requirements (for boundary fences)
Red flags: Wants to dig without calling 1100, skips concrete footings to save time, or does not mention the Dividing Fences Act process for shared boundaries.
How We Calculate
Estimates are based on current registered builder and fencing contractor rates across the Perth metropolitan area, adjusted for local material costs in WA. All prices include GST. Figures cover standard residential timber fencing. Colorbond, aluminium, and masonry fencing are separate trades and not included.
