Foundation and concrete work in Australia: what it costs

Updated 31 October 2026

Foundation and concrete work in Australia costs roughly A$75 to A$110 per square metre for a basic concrete slab, and A$4,000 to A$60,000 for a foundation repair, according to sellers' websites in October 2026. Most jobs are quoted per job, so the quickest way to a real total is a request on BlaBlaPrice with your dimensions and soil details.

Licences that depend on the state

Licensing depends on where the work is and how much it costs. In Queensland, a foundation work licence is needed for foundation work worth more than A$3,300. In Victoria, a footings and slabs licence covers projects over A$16,000. In New South Wales, a builder's licence is required for residential building work over A$5,000, with fees from A$830 to A$4,631. In Western Australia, only registered builders with a building permit may do building work totalling A$20,000 or more. Ask the builder for the licence number before you sign.

Season and site timing

October is spring here. Summer runs December to February and winter June to August, so the weather window changes through the year. Plan the excavation and pour for a dry spell, and ask the contractor how a wet week would move the schedule. Build that into your deadline rather than discovering it on site.

How the work is priced

Slabs and concrete are quoted per square metre, and thickness, finish and site preparation change the price. Foundation repairs depend on the extent of the damage and the repair method, so they are quoted per job. Give your measurements in metres and square metres, and state the slab thickness in millimetres if you know it.

What to put in your request

Give the work needed, the dimensions or volume, the soil and plot, whether you need reinforcement, the site address, your deadline and your budget. A photo of the site helps too. A 13 m long, 2 m high block wall with its foundations is far easier to quote than "a wall", so give the exact measurements.
