This year, new comprehensive climate change projections for Australia were produced by CSIRO and the Bureau of Meteorology in consultation with Natural Resource Management groups and Australian researchers.

Increasingly, end-users require access to projections through web-based services. Accordingly, a broad range of information and data products have been made available through the web-site, www.climatechangeinaustralia.gov.au .

The web-site aims to meet the needs of a range of users from newcomers through to experts seeking detailed datasets for use in impact assessments. A variety of interactive tools have been developed to deliver the information in an easy to understand form. During design and development, we met two major challenges: 1) handling the enormous datasets involved while providing the flexibility and responsiveness demanded by users; and 2) communicating the information in appealing and easy to use ways without compromising scientific credibility.

There are eight core web-tools: Australia's Future Climate, Summary Data Explorer,Climate Analogues Mapper, Map Explorer,Plume Plot Generator, Thresholds Calculator,Marine Explorer, and Australian Climate Futures. We will present a brief description of each web-tool and then briefly demonstrate two of them: Australia's Future Climate and the Map Explorer. The Australian Climate Futures web-tool will be demonstrated in a separate presentation.

Based on previous experience, we anticipate the web-site will be a major source of climate projections knowledge for the Australian community and provide quality data for use in impact assessments and adaptation programmes for years to come.
