The commission’s overall objective is to ensure all functions comply with legislative laws that govern its operations. In order to work ethically, efficiently and effectively, ESCOSA operates under a corporate governance framework. It is through this structure that the commission is able to excite its mandate.

ESCOSA has a diverse range of skilled employees, with backgrounds in sectors such as law, economics, engineering, accounting, IT, and human resources. It executes its operations through the organization’s structure. This entails three main groups, which handle consumer and regulatory affairs; pricing and analysis; as well as governance and strategy. Each structure in the commission plays a significant role in achieving the objectives set for in the Essential Services Commission Act.


The Essential Services Commission of South Australia believes in maintaining transparency. The commission invites all parties to provide their views with regard to regulation of essential services. Industry players can provide their diverse views along with evidence to help the commission decide on how best to enforce regulations or create better polices. Through consumer engagements and consultations, ESCOSA is able to provide a platform for local residents to be heard.
