Downer Blasting Services (DBS) is just one of the businesses that falls under the Downer Group umbrella. Their beginnings were modest, with the company starting as a small niche player in the Hunter Valley. At the time of their first acquisition, they had five projects and an emulsion-manufacturing facility. Over the next twenty years they would grow to be one of the largest blasting contractors in the Australian mining industry. https://ifactory.com.au/news/case-study-downer-blasting-services
