The Board of Land & Water Australia has identified Australia's unique tropical rivers and associated catchments and estuaries as a priority area for a major investment over five years from July 2005. Land & Water Australia is negotiating with potential partners, undertaking workshops and engaging with relevant States, the Northern Territory, Indigenous land councils and other stakeholders to build a shared vision for the program. Land & Water Australia is also inviting expressions of interest from prospective investors interested in partnerships in research and development to improve the knowledge base for managing Australia's tropical rivers and associated catchments and estuaries.
