Concrete Cost Per m² Australia: What Changes the Price and Why

Concrete pricing per square metre is useful for early budgeting, but it only tells part of the story. The final cost depends on the type of concrete, finish, thickness, reinforcement, preparation, access and what the concrete needs to do.

This guide explains how concrete cost per m² works in real projects, so you can compare quotes properly and choose the right service for your site.

How much does concrete cost per m² in Australia?

As a broad guide, concrete work in Australia commonly ranges from about $50 to $170+ per m². Basic resurfacing and plain concrete sit lower, while reinforced concrete, exposed aggregate, stencilled finishes and polished concrete usually sit higher.

Concrete type or finish Typical range per m² Best for Why it costs this much
Spray-on concrete $50–$75 Resurfacing existing concrete Lower material depth because it is a surface system, not a new full-depth slab.
Plain concrete $65–$100 Paths, basic driveways, utility areas Simple finish, fewer decorative steps and usually faster finishing.
Reinforced concrete $80–$135 Driveways, slabs, load-bearing areas Steel mesh, correct placement, thickness and base preparation increase cost.
Coloured concrete $90–$140 Decorative paths, driveways and outdoor areas Colour additives, surface control and finish consistency add time and material cost.
Exposed aggregate $100–$180+ Driveways, outdoor entertaining areas, street-facing surfaces Extra finishing, exposure timing, washing and sealing affect labour and risk.
Polished concrete $100–$300+ Indoor floors and high-end finishes Grinding depth, aggregate exposure, densifier, sealing system and finish level change cost.

Estimate concrete cost by square metre

Use this calculator for early budgeting. It gives a broad estimate only. Real pricing still depends on site inspection, preparation, drainage, access and final scope.

Estimated project range

$3,250 – $5,400

$65 – $108 per m²

This estimate is based on a standard plain concrete job with standard preparation and easy access.

  • Finish type changes labour and material cost.
  • Preparation affects the base, level and risk of future movement.
  • Small jobs can have a higher per-m² rate because setup costs are spread across less area.

Concrete cost per m² by finish type

Decorative finishes do not just add appearance. They add timing, surface control, extra labour and in some cases sealing or polishing systems.

Plain concrete
$65–$100/m²
Reinforced concrete
$80–$135/m²
Coloured concrete
$90–$140/m²
Exposed aggregate
$100–$180+/m²
Polished concrete
$100–$300+/m²

What is usually included in concrete cost per m²?

A per-m² rate usually compresses several parts of the job into one number. That can be helpful for budgeting, but it can also make quotes hard to compare if the scope is not clear.

A standard quote may include concrete supply, labour, pouring, screeding, basic finishing, standard formwork, basic clean-up and reinforcement where specified. But not every quote includes the same allowances.

Ask what is included before comparing prices. A lower per-m² rate may exclude excavation, old concrete removal, pump hire, drainage, disposal, sealing, engineering or saw cutting.

Costs that may sit outside the basic m² rate

Old concrete removal, tipping fees, difficult access, pump hire, drainage channels, council requirements, engineering, decorative sealing and extra cutting can all change the total price.

Concrete cost per m² by project type

The same square metre rate does not apply evenly across every job. A driveway, house slab, polished floor and repair job all have different requirements.

Project type Typical pricing behaviour Main cost drivers Best next page
Concrete driveways Medium to high Vehicle load, thickness, finish, drainage, access Concrete Driveways
Concrete slabs Medium to high Engineering, reinforcement, levels, slab thickness Concrete Slabs
Polished concrete Medium to premium Grinding depth, exposure level, sealing system, finish quality Polished Concrete
Exposed aggregate Medium to premium Aggregate selection, exposure timing, washing, sealing Exposed Aggregate
Concrete repairs Often not priced like new slabs Cause of damage, patch depth, access, matching existing finish Concrete Repairs
Concrete cutting Usually priced by scope, depth and complexity Cut depth, access, safety, disposal, equipment Concrete Cutting

Why concrete price per m² changes so much

Preparation changes the job before concrete arrives

Soft ground, uneven levels, old concrete, tree roots, poor drainage or unstable soil can all increase preparation. The surface area might be the same, but the work below the surface is different.

Thickness changes material volume

A thin path and a vehicle-rated driveway do not use the same amount of concrete. Extra thickness increases the cubic metres required and can also change reinforcement needs.

Reinforcement adds cost for a reason

Steel mesh, bar chairs and correct placement add labour and materials. They are not decorative items. They help the slab handle load and reduce the risk of movement-related failure.

Finish type changes labour timing

Plain concrete is usually faster to finish. Exposed aggregate needs controlled exposure and washing. Polished concrete needs grinding, densifying and sealing. Those extra steps are why finish choice can change the rate.

Access affects equipment and labour

Easy truck access keeps the job efficient. Tight side access, steep blocks, inner-city properties and long distances from truck to pour area can increase labour or require pumping.

Why two 50m² concrete jobs can cost different amounts

Per-m² pricing only makes sense when the scope is similar. These examples show why the same area can produce different totals.

Lower range

50m² plain concrete path

Easy access, minimal excavation and a simple finish keep the job straightforward. The concrete does not need to handle vehicle loads.

Middle range

50m² reinforced driveway

Vehicle loads mean stronger preparation, suitable thickness, reinforcement and control joints. Drainage may also need more attention.

Higher range

50m² exposed aggregate driveway

The base still needs to perform, but the finish also adds timing, washing, surface control and sealing.

Concrete per m² vs concrete per m³

Homeowners often think in square metres because they are measuring the surface area. Concrete supply is often calculated in cubic metres because concrete has depth.

Area × Thickness = Concrete Volume

For example, a 50m² slab at 100mm thick needs about 5m³ of concrete before waste allowance:

50 × 0.10 = 5m³

This is why thickness matters. A thicker slab may look the same from above, but it uses more concrete and may need different reinforcement.

How slab thickness changes concrete volume

Area Thickness Concrete volume before waste allowance What this means
50m² 75mm 3.75m³ Often suited to lighter non-vehicle areas, depending on site requirements.
50m² 100mm 5.00m³ Common planning thickness for many residential concrete areas.
50m² 125mm 6.25m³ Uses 25% more concrete than 100mm thickness.
50m² 150mm 7.50m³ Uses 50% more concrete than 100mm thickness.

Is the cheapest concrete per m² the best option?

Sometimes a lower-cost concrete option is fine. A simple path, small utility area or low-use outdoor space may not need a premium finish or heavy specification.

The cheapest option becomes risky when the concrete needs to carry vehicles, support a structure, deal with poor drainage or perform on unstable ground. In those cases, the cost of the base and preparation matters more than chasing the lowest surface price.

For vehicle areas, start with concrete driveways. For structural or outdoor slab work, see concrete slabs.

Quote comparison checklist

Before choosing a concreter, compare the scope behind the number.

Preparation

Does the quote explain excavation, base material, compaction and old concrete removal?

Thickness and reinforcement

Does it specify slab thickness, mesh, reinforcement type and where it will be used?

Drainage and levels

Does the scope explain how water will move away from the concrete and nearby structures?

Finish and sealing

Does it clearly state the finish type, sealing requirements and any maintenance expectations?

Why concrete cost changes by location

Concrete pricing can change between cities and suburbs because labour, access, soil conditions, disposal, travel time and weather are different across Australia.

Sydney

Dense suburbs, tight access, older properties and higher disposal or access complexity can change project pricing. View our Sydney concrete services.

Adelaide

Heat, site exposure, drainage and soil conditions can affect preparation and finishing decisions. View our Adelaide concrete services.

Frequently asked questions

How much does concrete cost per m² in Australia?

Concrete work in Australia commonly ranges from about $50 to $170 or more per square metre. Basic plain concrete and resurfacing sit lower, while exposed aggregate, reinforced concrete, stencilled finishes and polished concrete sit higher.

Why is reinforced concrete more expensive?

Reinforced concrete costs more because it includes steel mesh or other reinforcement, correct placement, extra handling and usually more careful base preparation.

Is exposed aggregate more expensive than plain concrete?

Yes. Exposed aggregate usually costs more because the finish needs controlled exposure, washing, surface timing and sealing.

Does concrete thickness affect cost?

Yes. Thickness affects the volume of concrete required. A 150mm slab uses 50% more concrete than a 100mm slab over the same area.

Is concrete priced by m² or m³?

Homeowners often compare concrete by square metre, while concrete supply is commonly calculated by cubic metre. Area multiplied by thickness gives the concrete volume.

Why do small concrete jobs cost more per m²?

Small jobs often have a higher per-m² rate because travel, setup, labour, formwork, equipment and minimum charges are spread across a smaller area.

What is the cheapest concrete finish?

Plain concrete is usually the cheapest full-depth concrete finish. Spray-on concrete can be cheaper, but it is a resurfacing option rather than a new structural pour.

How do I compare concrete quotes properly?

Compare the scope, not just the total. Check preparation, thickness, reinforcement, drainage, access, finish, sealing, removal and disposal allowances.
