Building cost by city and region

Only the New South Wales register publishes the cost an applicant declared. A region appears here for a project type once at least 30 applications of that type carried one.

The counts below were read on 2026-09-21. Every figure on a region page is read again when that page opens.

A declared cost of works is the applicant’s own estimate, filed so the council can work out a lodgement fee. It is not a contract price. Under the official definition it covers design and construction and excludes GST and the land.
