In December 2005, Girringun traditional owners signed the first ever such agreement in Australia for the management of traditional hunting of protected species in the greater Hinchinbrook Island area.  This agreement was subsequently accredited by the GBRMPA (Great Barrier Reef Marine Park Authority) and the EPA (Environment Protection Authority).  Implementation of the agreement is steered by the Girringun TUMRA Steering Committee which can be contacted through this organisation.

TUMRA established a formal agreement between Saltwater Traditional Owners, GBRMPA (Great Barrier Reef Marine Park Authority) and QPWS (Queensland Parks and Wildlife Service) and how collectively Traditional Owners manage traditional take of turtles and dugong.
