Cost Breakdown
How Much Concrete Do I Need?
The amount of concrete required depends on your project dimensions. For slabs, multiply length by width by thickness. Always order 5–10% extra to account for wastage, spillage, and ground irregularities.
Standard concrete thickness: Paths (75–100mm), Patios (100mm), Driveways (100–125mm), Heavy duty areas (150mm+).
Concrete Cost Per Square Metre
In 2025, concrete costs in Australia range from $280–$420 per cubic metre depending on the mix type and location. For a standard 100mm thick slab, this translates to approximately $28–$42 per square metre for materials.
Total installed costs including labour typically range from $65–$110 per m² depending on project complexity.
