Project: Lower Murrumbidgee – Gayini (Nimmie Caira), NSW

The Gayini Nimmie-Caira property is approximately 84,000 hectares of freehold land covering open lignum floodplain in the lower Murrumbidgee Valley between Hay and Balranald, making it one of the largest single private holdings in the Riverina bioregion. The area is unique in containing large areas of continuous lignum through key floodways which support nationally-significant colonial nesting waterbird rookeries. The Lower Bidgee wetland system is the largest wetland in the Murrumbidgee Valley, and is listed on the Directory of Important Wetlands of Australia. It contains river redgum and black box forests and woodlands, as well as grasslands and chenopod shrublands, and is also home to a range of threatened species, including the largest known population of the endangered southern bell frog in NSW.

Gayini Nimmie-Cairai is cuilturally rich as it was home to the Nari Nari people for over 60000 years. The Nari Nari are now working with us to ensure significant areas of occupation across the area are protected, maintain and enhanced.

Our approach

A consortium of partners will lead the rehabilitation and rejuvenation of Gayine Nimmie-Caira. Our goal is for Nimmie Caira to be an exemplar of Indigenous-led, culture-based enterprise that sustains healthy Country, responsible agriculture, education, research and independent Indigenous livelihoods.  The consortium brings together leading science and conservation, Traditional Knowledge, community partnerships, and a long history of sustainable agriculture to deliver a world’s best approach to the holistic management of land and water at Gayini Nimmie-Caira.  A Land and Water Management Plan has been developed to guide activities over the next 10 years.


The overarching land and water management objectives for the Nimmie-Caira are to:

  • protect, maintain and enhance environmental values such as floodplain vegetation, bird habitat and southern bell frog populations
  • protect, maintain and enhance Aboriginal Cultural Heritage values 
  • create economic value from the Nimmie-Caira without compromising environmental and Aboriginal Cultural Heritage objectives.
