Timber Deck vs Concrete Patio Cost Brisbane — At a Glance for AU
The deck-versus-slab choice runs A$150–A$480 per square metre installed — the surface and the site carrying the range. This is a realistic planning number for Australia in 2026, not a marketing low-ball.
| Line Item | Typical Range (AUD) | What Drives It |
|---|---|---|
| Timber deck installed per square metre | A$300–A$480 | The hardwood at the Brisbane rate |
| Concrete slab patio per square metre | A$150–A$250 | The poured finish at the budget |
| Decorative concrete upgrade | A$220–A$380 | The exposed or the coloured finish |
| Site excavation difference | A$19–A$62 | The slab at the cut and fill |

Understanding Timber Deck vs Concrete Patio Cost Brisbane
The timber decks running $240-$380 per square metre — the hardwood character at the Brisbane labour. The concrete slabs at $120-$200 — the poured budget path. The decorative concrete at $180-$300 at the mid-tier finish.
The site at the decision: the slopes and the drains favouring the deck at the posts; the flat sites at the slab efficiency. The Queensland heat at the surfaces — the timber at the barefoot comfort; the concrete at the thermal mass. The maintenance streams: the deck at the 12-18 month oiling; the slab at the sealing at the 5-10 year scope.
What Moves the Price Up or Down
The price moves with the surface choice, the site grade, the finish tier, and the maintenance stream.
| Factor | Cost Impact | Detail |
|---|---|---|
| Surface choice | +40-60% | The deck against the slab |
| Site grade and excavation | +10-25% | The cut and fill at the slab |
| Finish tier | +20-40% | The decorative against the plain |
| Brisbane labour window | +10-20% | The pre-Christmas rush |
| Maintenance stream | +10-20% | The oiling against the sealing |
Brisbane Outdoor Surface Options
Three surfaces serve the yard — the deck, the slab, the decorative trading.
| Option | Description | Best For | Cost Level |
|---|---|---|---|
| Hardwood timber deck | The character at the slope tolerance | The lifestyle builds | $240-$380 per m2 |
| Concrete slab | The budget at the flat sites | The utility patios | $120-$200 per m2 |
| Decorative concrete | The exposed finish at the mid-tier | The presentation builds | $180-$300 per m2 |
The deck serving the lifestyle — the slab serving the budget at the flat sites.
Three Realistic Project Scenarios
The family timber deck — A$9,000–A$14,250
A 30 square metre hardwood deck at the posts.
- Boards and frame — A$5,620–A$8,910
- Posts and labour — A$3,380–A$5,340
Why this matters: The deck path serves the lifestyle — the 30 m2 at the $9,300 total with the character priced.
The budget slab patio — A$4,500–A$7,500
A 30 square metre concrete patio at the flat site.
- Slab and excavation — A$4,500–A$7,500
Why this matters: The slab path serves the budget — the 30 m2 at the $4,800 total with the poured finish honestly.
The decorative mid-tier — A$6,750–A$11,250
A 30 square metre exposed-aggregate patio.
- Decorative slab — A$6,750–A$11,250
Why this matters: The decorative path serves the presentation — the 30 m2 at the $7,200 total with the exposed finish.
The scenarios share the footprint — the surface choice and the site grade separating the totals.

From Quote to Completion: the Typical Timeline
Most timber deck vs concrete patio cost brisbane projects follow the same five-stage rhythm. Knowing the calendar before you sign prevents the two classic frustrations — feeling rushed into a deposit, and being surprised by a mid-project gap while materials arrive.
- Design and quoting — 2-4 weeks
- Timber delivery and acclimatisation — 1-2 weeks
- Frame and board install — 1-2 weeks typical
- Final oil coat and handover — 2-4 weeks after install
- Design and quoting — 2-4 weeks
Smart Ways to Control the Budget
Cost control on timber deck vs concrete patio cost brisbane is mostly about scope discipline and timing. These are the strategies that consistently deliver the largest savings:
Price the species by the lifespan, not the sticker
Merbau at $55-90 per square metre supplied against the treated pine at $25-40 — the 25-year hardwood lifespan against the 10-15 year pine cycle. The total ownership math pricing the honest comparison over the decades, not the build day.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- Requires the decades framing at the timber yard.
- Requires planning lead-time you may not have on urgent timelines
Buy boards in the one moisture-stabilised batch
The single-batch supply at the consistent moisture content pricing the even gaps — the mixed batches shrinking unevenly and producing the irregular spacing. The batch number recorded at the delivery docket.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- Takes the full-quantity order at the one delivery.
- Requires planning lead-time you may not have on urgent timelines
Price the frame separately from the boards
The H3 treated pine frame at $15-25 per square metre against the hardwood subframe at $40-70 — the pine frame at the code-approved path under the merbau surface. The frame spec quoted line by line, never bundled.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- The frame and the boards priced as separate lines at the quote.
- Requires planning lead-time you may not have on urgent timelines
Time the install for the shoulder season
The spring and autumn install windows at the standard rates — the summer rush pricing the 15-25% premium at the peak. The winter quoting serving the honest availability and the off-season rate cards.
Advantages:
- Directly reduces the controllable parts of the quote
- No impact on quality or compliance when scoped correctly
Disadvantages:
- Requires the booking at the quiet season.
- Requires planning lead-time you may not have on urgent timelines
Permits, Rules and Safety
Both surfaces at the permit scope — the decks at the structure and the slabs at the site works. The standard footprints at the exempt path at most Brisbane councils honestly.
- (‘Setback and boundary review’, ‘$0-150’, ‘The boundary clearances at the site plan — the attached structures at the easement and the setback rules.’, ‘The site plan checked at the quoting stage.’)
- (‘Deck permit’, ‘$100-400 typical in AU councils’, ‘The structural review at the footings, the frame, and the balustrade code — the over-1-metre heights and the pool zones always at the permit scope.’, ‘The unpermitted deck pricing the resale disclosure.’)
- (‘Pool zone compliance check’, ‘$0-250’, ‘The pool-adjacent decks at the CPRC non-climbable zone review — the barrier code at the pool vicinity scope.’, ‘Applies at every deck within the pool zone.’)
Maintenance and Long-Term Ownership Costs
The project price is only the first line of the budget. These recurring items are what owners in Australia actually spend money on after the crews leave:
| Task | Frequency | Typical Cost | Why It Matters |
|---|---|---|---|
| Deck wash | Yearly | $100-300 | The surface grime and the mildew at the gentle wash — the coating adhesion protected at the clean surface. |
| Deck oil | Every 12-18 months | $4-8/sq m | The timber hydrated at the oiling cycle — the neglect pricing the grey restoration at the multiple of the maintenance. |
| Fastener and joist check | Yearly | $0-150 | The screws and the hangers at the movement cycle — the structural issues caught at the walk. |
| Inspection walk | Yearly | $0-250 | The structure, the fasteners, and the gaps walked at the season — the issues caught at the early stage. |
The deck at the 12-18 month oiling at $4-$8 per square metre; the slab at the 5-10 year sealing at $8-$15. The streams at the decades honestly compared.
