Douglas Partners acknowledges Australia’s First Peoples as the Traditional Owners of the Land and Sea on which we operate.

We pay our respects to Elders past and present and to all Aboriginal and Torres Strait Islander peoples across the many communities in which we live, visit and work. We recognise and respect their ongoing cultural and spiritual connection to Country.
