Social Impact Assessment (SIA) is a critical part of predicting, measuring and managing the impacts of development. Maximising opportunities associated with development and minimising potential negative impacts of change are critical, in particular for the protection of the interests of vulnerable peoples. Social Impact Assessment reports provide insights and input into agreement-making and offer value for money in that undoing harmful impacts is expensive compared to the cost of identifying and preventing such impacts in the first instance. Social Impact Investing Queensland works closely with ImpaxSIA Consulting to provide quality social impact assessments for resource development and infrastructure development planning. ImpaxSIA is one of Australia's leader providers in social impact assessment with over 25 major SIAs and with specialist expertise in linear projects and resource development, including oil and gas.
