Broadhectare study

Residential land supply in Queensland is monitored by QGSO in our broadhectare study.  A broadhectare study identifies the location and quantifies the area, timing of development and dwelling yield of larger land parcels to house a specified region’s growing population.

Broadhectare studies are available for South East Queensland and other regions throughout Queensland.

Each study involves consultation and collaboration with local government, the Urban Development Institute of Australia (Queensland) and major developers.

A measure of future residential land supply

The land identified in the broadhectare study is the first stage in the land development pipeline. It includes parcels of land identified as suitable and potentially available for future residential development. The study focuses on land parcels greater than 0.25 ha.

The identified residential land is categorised according to development potential as for either urban or rural residential use. The timing for land development is based on local government infrastructure extension programs, recent lot approvals and the development intentions of major developers. Timing is divided into the following five categories:

The category ‘not specified’ also includes smaller parcels in existing developed areas where development occurs randomly (depending on the owners’ intentions).


The spatial analysis process utilised in the broadhectare study involves creating segments based on the Digital Cadastral Database (DCDB) over each local government area. Each segment is then updated with data that impact on the suitability and availability for residential development. Using rule-based filtering, broadhectare land stocks are identified.
