What Affects the Cost
Fence length. Adelaide blocks in established inner suburbs (Norwood, Unley, Prospect) are on the smaller side, keeping fence runs shorter than Perth or Melbourne. Newer suburbs in the north (Munno Para, Angle Vale) and south (Seaford, Aldinga) have larger blocks with longer boundaries.
Timber species. Treated pine paling at $75–$120/m installed is the standard for boundary fences. Hardwood at $180–$350/m is used for feature fences and heritage areas where the aesthetic matters. Timber picket fences ($120–$200/m) are commonly required in character overlay zones.
Colorbond steel. Adelaide is home to Stratco, one of Australia's largest Colorbond fencing manufacturers. Their Good Neighbour range starts at around $121 per panel (supply only), with fully installed Colorbond running $180–$300 per metre. Colorbond is a strong choice in reactive clay areas because steel posts eliminate rot and soil-movement issues that affect timber.
Reactive clay soils. Suburbs in Adelaide's north (Salisbury, Elizabeth, Parafield Gardens) and south (Morphett Vale, Hackham, Reynella) sit on Class H to E reactive clay. Posts need deeper footings (750mm+) and wider concrete pads to resist soil movement.
Heritage restrictions. Properties in heritage or character overlay areas in the eastern suburbs and Adelaide Hills face restrictions on fence style, height, and materials.
Ground slope. Hills-area properties (Stirling, Crafers, Blackwood, Bridgewater) often have significant ground slope along boundaries, requiring stepped or raked fence panels that add 15–25% to the per-metre rate.
A 15-metre treated pine paling fence on a flat block in a newer northern suburb with easy access sits toward $1,700. A full-boundary hardwood fence on a sloping Hills block with deep-set posts in reactive clay, heritage design requirements, and driveway gates pushes toward $8,800.
Adelaide-Specific Considerations
Reactive clay soils in the north and south. Large parts of Adelaide's northern plains (Salisbury, Elizabeth, Parafield Gardens, Smithfield) and southern suburbs (Morphett Vale, Hackham, Reynella, Christies Beach) sit on reactive clay, classified H (high), H1, H2, or E (extreme) under AS 2870. This clay swells when wet and shrinks when dry, putting lateral pressure on fence posts and causing them to lean over time. Standard 600mm footings are often insufficient. A good contractor will specify deeper footings (750mm+) and wider concrete pads in these areas. Galvanised steel posts ($14–$20 each) are worth considering in reactive clay because they resist the moisture cycling that causes timber posts to deteriorate faster.
Heritage and character fencing in the east. Suburbs like Burnside, Unley, Norwood, Walkerville, and Adelaide Hills townships (Stirling, Aldgate, Hahndorf) often have heritage or character overlay requirements that affect front fencing. Front fences may need to be timber picket-style or sympathetic to the period of the home, with specific height limits, materials, and colour palettes dictated by your council's Development Plan. Check with your local council before choosing a design. Planning permit fees and processing time apply on top of the build cost.
Colorbond and Stratco in Adelaide. Stratco, headquartered in Adelaide, is one of Australia's largest manufacturers of COLORBOND steel fencing. This means Adelaide has strong local supply and competitive pricing for Colorbond fencing compared to other capitals. The Good Neighbour profile looks identical on both sides, which avoids the neighbour getting the "bad side." In reactive clay areas, Colorbond on steel posts is a practical choice because it sidesteps both the soil movement and termite issues that affect timber.
SA Fences Act 1975. South Australia's cost-sharing legislation under the Fences Act 1975 requires you to give your neighbour written notice at least 30 days before starting fence work on a shared boundary. The notice must describe the proposed fence and estimated cost. If the neighbour disagrees, the matter can go to the SA Civil and Administrative Tribunal (SACAT). You must wait the full 30 days before commencing work, or you lose the right to recover costs from your neighbour. Most fencing contractors in Adelaide are familiar with this process.
Smaller inner-suburban blocks. Adelaide's inner suburbs (Prospect, Norwood, Goodwood, Mile End) have some of the most compact blocks of any Australian capital. Shorter boundary fences mean lower total costs, but access can be tight through older homes, adding labour time for hand-carrying materials.
Dial Before You Dig. Call 1100 before digging any post holes. Gas, water, and telecom services run along property boundaries throughout Adelaide.
Hiring a Licensed Carpenter in SA
In South Australia, a Building Work Contractor's Licence is required for building work. This is administered by Consumer and Business Services (CBS). You can verify a contractor's licence on the CBS licence holder search.
Ask for:
Building Work Contractor's Licence number
Proof of public liability insurance
A written quote with per-metre pricing, timber species, treatment grade (H4 for posts), and post depth
Explanation of the SA Fences Act 30-day notice process
Dial Before You Dig confirmation
Worth checking:
A good contractor will specify deeper footings in known reactive clay areas
They will explain the SA Fences Act notice process and 30-day waiting period
They will have called Dial Before You Dig before any excavation
They will offer both timber and Colorbond options so you can compare
Once the fence is up, timber fences in Adelaide's dry climate benefit from a protective stain every 2–3 years. See our deck and fence painting guide for product options and costs.
How We Calculate
Estimates are based on current licensed fencing contractor and carpenter rates across the Adelaide metropolitan area, adjusted for material costs in SA. All prices include GST. Figures cover standard residential timber fencing. Colorbond, aluminium, pool fencing, and masonry walls may fall outside these ranges.
