Budget check
Put a bracket on it before anyone visits
These are the Cardinia rates our quotes are being written from right now (September 2026). Working rates until we measure the job; after that the written quote is the price, full stop.
What it is doing with your numbers
Area times the current band for the job, plus $35 per square metre when an old surface has to come out, plus fifteen percent when the site is sloped, tight or needs a staged pour. Shire permit fees stay out because they belong to the council, not the contractor. The result is a truthful bracket for planning; the single figure comes from a free measure. The cost guide unpacks each input and the specification shows what every rate is built from.
