The Indigenous Estate in Australia is a vast and complex system of land, resources, and people. Positioned as a systemic wicked problem, it is difficult to define, understand, and solve, impacted upon by overlapping, complex and contradictory policy. One of the main challenges facing the Indigenous Estate is the dominance of western business models that do not respond to Indigenous priorities for self-determination. This leads to restrictive practices such as asset stripping, corporate assimilation, and environmental degradation. Indigenous knowledges offer a way forward to address the challenges within the Indigenous Estate, to resist assimilation and build benefit for community and country. This knowledge is established through a cultural and spiritual base to care for country and community, and principles of respectful design, which can be used to develop business models that are place-based, sustainable, and beneficial to everyone. The aim of the chapter is to first shape the definition of the Indigenous Estate in Australia, second is to position the Indigenous Estate as a wicked complex problem, third is to present the Gongan Business Model as an example of an Indigenous Knowledges soft system methodology and finally outline directions for future research. We draw on the Gongan Business Model as an example of how Indigenous knowledges can be foundational to business design, offering solutions to the wicked complex problems of the estate. We argue that the Indigenous Estate is a ‘wicked complex problem’ requiring strategies and application of Indigenous knowledges in business and community contexts. These insights are essential for ensuring long-term cultural, social, environmental, political, and economic sustainability of the Indigenous Estate fostering a more sustainable, equitable, and prosperous future for all people living in Australia.
