Master Builders Association of South Australia

Master Builders Association of South Australia Inc (“Master Builders SA”) was established in 1884 as the peak body representing South Australia’s building and construction industry.

Master Builders SA is committed to building a productive industry and a prosperous South Australian community and economy.

The South Australian building and construction industry directly employs more than 65,000 South Australians across all sectors, including residential, commercial, civil engineering, land development and building completion services. Indirectly, the industry supports tens of thousands more South Australian jobs.

The industry undertakes about $16 billion of work every year, contributing more than $1 for every $7 of economic activity within the State. Indirectly, more than one-quarter of South Australia’s wealth is produced by the building and construction industry.

South Australia’s building and construction industry is focused on the development and transfer of skills into a life-long career. It is consistently among the leading sectors when it comes to training and apprentices and last year provided new apprentice places for more young workers than the Northern Territory, ACT and Tasmania combined.

Master Builders SA is proud of the industry it represents, the jobs it creates, the 11,000 homes it built and extended for families last year and commercial premises it has built for South Australian businesses.
