How Much Does Excavation Cost in Brisbane? (2026 Price Guide)

How Much Does Excavation Cost in Brisbane?

Whether you are preparing a site for a new concrete driveway, digging footings for a retaining wall, or levelling ground for a shed slab, excavation is often the first step in any concreting project. Understanding what excavation costs in Brisbane helps you budget accurately and avoid surprises when the quotes come in.

The short answer: excavation in Brisbane typically costs between $80 and $250 per hour for equipment and operator, or $30 to $200 per cubic metre depending on the soil type, access, and volume of material to be removed. Most residential excavation jobs for concreting projects fall between $1,500 and $5,000.

This guide breaks down excavation pricing by method, common project types, the factors that affect cost, and how to keep your excavation bill as low as possible.

Excavation Cost Per Hour (Brisbane 2026)

Most excavation contractors in Brisbane charge by the hour, with rates varying based on the size of equipment needed. Here are typical hourly rates including the operator:

Equipment Type	Hourly Rate (Wet Hire)	Best For
Mini excavator (1.5 – 2 tonne)	$80 – $130	Tight access, small trenches, garden work
Bobcat / skid steer	$100 – $140	Site levelling, driveway prep, spreading
Medium excavator (5 – 6 tonne)	$130 – $180	Driveway excavation, retaining wall footings
Large excavator (12 – 20 tonne)	$180 – $280	Major earthworks, pool excavation, house sites
Tipper truck (for soil removal)	$90 – $150	Carting excavated material to tip

"Wet hire" means the rate includes the operator. "Dry hire" (machine only, you supply the operator) is cheaper but requires someone with the right tickets to operate the equipment. For most residential concreting projects, wet hire is the standard approach.

Excavation Cost Per Cubic Metre

Some contractors quote by volume rather than by the hour, which can be easier to compare across quotes. Typical rates per cubic metre in Brisbane:

Soil Type	Cost Per m³ (Excavate + Load)	Notes
Standard soil (clay, loam)	$30 – $80	Most common in Brisbane residential
Hard clay or compacted fill	$60 – $120	Common in established suburbs
Soft rock or shale	$80 – $150	Hilly suburbs, requires breaker
Hard rock (basalt, sandstone)	$120 – $250+	May need rock hammer attachment

These rates cover excavation and loading onto a truck. They do not include tip fees for disposing of the material, which are an additional cost covered below.

What Does a Typical Excavation Project Cost?

Here is what Brisbane homeowners typically pay for common excavation projects related to concreting work in 2026:

Project Type	Typical Scope	Estimated Total Cost
Driveway removal and preparation	Remove old concrete + excavate sub-base (50-80 m²)	$1,500 – $4,000
Shed slab site preparation	Level and compact pad (20-40 m²)	$800 – $2,500
Patio or entertaining area prep	Excavate and level (15-30 m²)	$600 – $2,000
Retaining wall footing trench	Dig footing trench (10-20 m long)	$500 – $2,000
Pool excavation	Full pool dig (standard fibreglass)	$3,000 – $8,000
House slab site cut	Cut and fill for house pad	$5,000 – $15,000+
Pathway or side access excavation	Remove old surface + prep (10-20 m²)	$400 – $1,200

These estimates include equipment hire, operator, and basic soil removal. Tip fees, rock breaking, and difficult access are additional costs.

Tip Fees: The Hidden Cost of Excavation

One cost that catches many homeowners off guard is the tip fee for disposing of excavated material. In Brisbane and surrounding areas, tip fees in 2026 are approximately:

Material Type	Tip Fee Per m³	Tip Fee Per Tonne
Clean fill (soil, clay)	$30 – $60	$20 – $40
Mixed fill (soil with some debris)	$60 – $100	$40 – $70
Concrete and rubble	$40 – $80	$30 – $55
Contaminated soil	$100 – $200+	$80 – $150+
Green waste (roots, vegetation)	$40 – $70	$30 – $50

For a typical driveway excavation that generates 10 to 15 cubic metres of spoil, tip fees alone can add $300 to $900 to the total cost. Some contractors include tip fees in their quote while others list them separately — always check.

7 Factors That Affect Excavation Cost in Brisbane

1. Soil Type

Brisbane's geology varies dramatically by suburb. Sandy soils in bayside suburbs like Wynnum and Redlands are easy to dig. Heavy clay in Logan and Springfield requires more effort. Rocky ground in hilly suburbs like Mt Gravatt, Paddington, and The Gap can double or triple excavation time and may require a rock breaker attachment ($50 to $100 per hour extra).

2. Access to the Site

If the excavator can drive straight to the work area, the job is straightforward. If it needs to be craned over a house, track through a narrow side gate, or work in a confined rear yard, expect to pay more. Some jobs in inner-city Brisbane suburbs with tight access may require a mini excavator (slower but fits through standard gates) instead of a larger, more efficient machine.

3. Depth and Volume

Shallow excavation (100 to 200mm for a driveway sub-base) is quick work. Deep excavation (1 metre+ for retaining wall footings or pool digs) takes longer and generates more spoil to remove. The more cubic metres of material that need to be dug and carted away, the higher the cost.

4. Underground Services

Before any excavation begins, a Dial Before You Dig (DBYD) search should be completed to identify underground water, sewer, gas, electrical, and telecommunications services. If services are present in the excavation area, hand digging or vacuum excavation may be required near them, which is slower and more expensive than machine excavation.

5. Existing Concrete or Structures

If old concrete needs to be broken up and removed before new excavation can begin, this adds to the cost. Concrete demolition typically costs $30 to $60 per square metre depending on thickness, plus removal and tip fees. Reinforced concrete with steel mesh costs more to break and dispose of.

6. Distance to Tip

The further the tip site is from your property, the more you will pay for cartage. Each truck trip takes time, and if the nearest tip is 30+ minutes away, the tipper truck spends more time driving than working. In outer Brisbane suburbs, this can add significantly to the total cost.

7. Weather and Timing

Brisbane's wet season (December to March) can make excavation more difficult and expensive. Wet clay becomes heavy and sticky, slopes become unstable, and trucks can damage soft ground. If possible, scheduling excavation during the drier months (April to November) can result in a smoother, faster, and cheaper job.

How to Save Money on Excavation in Brisbane

Get at least three quotes. Excavation pricing varies widely between contractors. Make sure each quote specifies whether tip fees, rock breaking, and travel time are included.

Combine excavation with your concreting job. Many concreters (including Concrete Concepts Group) handle excavation and site preparation as part of the overall project. This avoids the cost and coordination of hiring a separate excavation contractor.

Keep access clear. Before the excavator arrives, remove anything that might slow access — garden furniture, pot plants, fencing panels, overhanging branches. Every hour saved is money saved.

Know your soil. If you suspect rock on your property (common in hilly Brisbane suburbs), mention it when getting quotes. A contractor who brings the right equipment the first time avoids costly return trips.

Complete your Dial Before You Dig search early. This free service takes 2 to 3 business days and identifies underground services. Having this information ready when contractors quote means they can price the job accurately.

Consider reusing clean fill. If you have low areas on your property that need filling, excavated soil can sometimes be reused on-site instead of being carted to the tip, saving hundreds in tip fees and cartage.
