Ekistica is a leading advisory and technical consultancy firm in regional Australia. We work nationally and internationally with clients in challenging engineering and project development and delivery problems.

Established in 2007 by our parent company, the Indigenous controlled Centre for Appropriate Technology Ltd, our team of professional project managers includes electrical, renewable, environmental, civil, structural and mechanical engineers, engagement specialists, data analysts and IT systems and financial experts. Read more about our people here.

We have delivered many successful projects, across a range of different markets, including a number of ground-breaking projects that challenged the status quo. Many of our most prominent projects are in the renewable energy sector, however, our underlying principles and philosophies are what have allowed us to be innovative and successful across a broader range of infrastructure and technology projects.

Our key strength is our unique comprehension of the challenges associated with developing and building infrastructure in remote, regional or marginalised areas. An understanding that there are a common set of barriers to all remote area infrastructure development which are key determinants to a project’s success or failure:

  1. People and governance: people matter, and so too does the interface between people and the governance and regulatory frameworks that a project operates in.
  2. Technology and supply chains: cost and quality are critical but must be contextualized by consideration for the intellectual, labour and logistical supply chains available to support delivery.
  3. Finance: capital cost equations require consideration of the valuation of risk and the extant capital constraints in potential finance markets.

Ekistica is well-regarded for successfully delivering projects and providing quality independent advice to clients nationally and internationally. Our processes and ISO 9001 accredited Quality Management System ensure all our services are delivered to a consistently high standard.

Indigenous communities around the world are constantly impacted by the decisions of others and type-cast as importers of knowledge.

Ekistica was established to reverse this model, to export the Centre for Appropriate Technology Ltd’s more than 35 years of experience working in remote areas to other contexts and locations; and to constructively impact the world around us, to help shape the world we are all part of and to demonstrate that this can be done from a remote area, with remote area knowledge.

Established in 2007, Ekistica is the commercial services arm of the Centre for Appropriate Technology Ltd, a not-for-profit corporation working creatively at the interface of technology and economy in Aboriginal and Torres Strait Islander communities. The Centre for Appropriate Technology Ltd is owned and governed by an Aboriginal and Torres Strait Islander Board and knows a thing or two about working in remote areas and how to design and deliver services to the people and communities who live there.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.
