A large team of scientists in CSIRO and Bureau of Meteorology have now completed new climate change projections for Australia.  These are based on extensive analysis of the CMIP5 climate model ensemble and are focussed on each of fifteen regions around Australia. Associated products include a Technical Report, a series of regional reports, and an extensive website.  These projections form part of a larger project developed with funding from the Commonwealth’s Government Regional Natural Resources Management Planning for Climate Change Fund. This fund was established to support regional Natural Resource Management (NRM) organisations to update their plans to account for likely climate change impacts.  The projections cover a range of variables, such as temperature, precipitation, sea level rise, humidity, and radiation, including some aspects of extremes, such as hot days and extreme rainfall.  Development of these projections included extensive consultation with natural resource management planners and associated impacts and adaptation researchers to ensure that the projections met their needs and expectations. A variety of information is provided to meet a diversity of user needs. Key messages on regional climate change, including confidence statements have been published for narrative focussed use. For further modelling and regional planning projection data sets have been prepared in various user friendly formats. Communication products aimed at a wider audience, such as brochures, have also been developed.

The presentation will illustrate the approach used to develop projections, as well as showing final results across a range of variables and regions.
