Excavation Cost Calculator
Estimate the cost of excavation. The scale of the job and how easy the site is to access are the main cost drivers, along with any making-good afterwards.
Your excavation details
Your estimate sits within the typical range.
Spoil (dirt) removal is often underestimated, carting it away can cost as much as the digging. Rock is the big unknown, if you hit rock, breaking it is slow and expensive, so a site assessment helps avoid a nasty surprise.

- Clear and prepare the area yourself where you safely can, you are paying tradie rates for any time spent shifting your gear.
- Bundle related jobs into one visit so you pay the call-out and setup once.

Understanding excavation costs in Australia
Excavation in Australia typically costs around $500 to $2,000 in 2026 for small trench and footing work, rising to $5,000 to $15,000 or more for pool holes, garage pads, basements and site cuts, plus spoil removal and any rock breaking.
Excavation is priced by the volume dug, the machine needed, and how far the spoil must be carted. Access and rock are the big variables, tight sites slow the machines and rock dramatically raises the cost.
Frequently asked questions
How much does excavation cost in Australia?
Roughly $500 to $2,000 in 2026 for small trench and footing work, and $5,000 to $15,000 or more for pool holes, pads and site cuts, plus spoil removal and rock breaking.
Why is spoil removal a separate cost?
The dirt dug out (spoil) has to be carted away and disposed of, often many truckloads, and that can cost as much as the digging itself. It is priced separately because it depends on volume and tip fees.
