Dated versions never change. ## Query The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/qld-qbcc-licensed-contractors/rows. Counts and sums: https://publicdata.au/api/v1/datasets/qld-qbcc-licensed-contractors/aggregate. - Rows: https://publicdata.au/api/v1/datasets/qld-qbcc-licensed-contractors/rows?licence_grade=eq.Trade%20Contractor%20Licence&limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/qld-qbcc-licensed-contractors/aggregate?group=licence_class&metric=count&licence_grade=eq.Trade%20Contractor%20Licence Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`. - `select`: Fields to return, comma-separated. Every field when absent. - `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent. - `limit`: Rows per page, 1 to 10,000. 100 when absent. - `offset`: Rows to skip. The `next` URL in each answer sets it for you. - `group`: On `aggregate`, fields to group by, comma-separated. - `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent. - `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers. Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions//` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets//versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

The CSV also opens in Excel. https://publicdata.au/d/qld-qbcc-licensed-contractors/v/2026-09-23/data.csv.gz is the CSV at about a tenth of the size. ### How often is QBCC licensed builders and contractors register updated? QBCC releases it monthly. This site checks the portal every week and adds a dated version when the file changes. ### Can I use QBCC licensed builders and contractors register commercially? Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file. ### Is this the official source for QBCC licensed builders and contractors register? No. The publisher is Queensland Building and Construction Commission, and its page is https://www.data.qld.gov.au/dataset/qbcc-licensed-contractors-register. This site republishes the publisher's file without changing its content. The original sits beside every version as source.csv with its SHA-256, so the two can be compared. ### How do I get only the rows for one licence grade? Every version has one JSON file per value of licence_grade, 12 files in the current version, listed with row counts at https://publicdata.au/d/qld-qbcc-licensed-contractors/v/2026-09-23/by/licence_grade/index.json. For example https://publicdata.au/d/qld-qbcc-licensed-contractors/v/2026-09-23/by/licence_grade/trade-contractor-licence.json holds the 107,473 rows where licence_grade is Trade Contractor Licence. ### What is in each row? One licence class held by one licensee, with the licence number, the licensee's name, ACN or ABN where given, business address, whether the licensee is an individual or a company, the financial category and the licence grade and class, such as a trade contractor licence for plumbing and drainage. A licensee with several classes has several rows under one licence number. ### Are cancelled licences included? No. The commission includes active licences and suspended ones, and leaves out cancelled licences. It points readers to its online licence search for the status of an individual licensee on a given day. ### How current is it? The commission states the file is current as at the date it was generated, 23 September 2026 in the first version here, and replaces it from time to time. ## What this site did to the data Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.csv`. ## Improve this dataset This page is built from [register/qld-qbcc-licensed-contractors.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/qld-qbcc-licensed-contractors.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
