How does Starworks rank quantity surveyors nationally?

To rank quantity surveyors across Australia, Starworks combines each business's Google star rating, its review volume, and whether customers can reach it by website and phone. Volume is weighted because it shows how much evidence stands behind a rating, so a 4.9-star quantity surveyor with 200 reviews ranks above a 5-star one with 5 reviews. Placement cannot be bought. For scale, the median rating across the 123 quantity surveyors in Australia is 5.0 stars from a median of 3 reviews.

Where can I find the best quantity surveyors in my city?

Starworks publishes a separate ranking for quantity surveyors in every Australian city and suburb it holds enough data for, each built from that place's own Google review record rather than from this national list. Browse by city below.

Why does my quantity surveyor business not appear in these national rankings?

Starworks ranks public Google Maps data, so a business needs a Google profile in the quantity surveyor category carrying at least one review and a rating to be eligible. This national ranking of quantity surveyors in Australia lists the top 50 of 123 quantity surveyors; a business ranked outside them appears on its own city page wherever Starworks holds enough data for that city.
