This is a short and informative 5.0 minute movie for the Engineering, Economics and Exposure Project - NEXIS Development for DCCEE. This second version of the movie is based on the original NEXIS movie (10-4830 created in late 2010). This 11-5376 movie is a promotional movie that demonstrates NEXIS capabilities, and explains how NEXIS will be benefitial to the NEXIS stakeholder. This movie may also go onto the web, where it's purpose is to convince the public that NEXIS is a worthwhile investment in Australia's future.

Power point presentation given to a meeting of earthquake hazard model stakeholders, in Sydney on July 22nd 2008.

This paper is an introduction to the two AJEM Special Issues on risk assessment. The role of risk assessment in emergency management in Australia is firmly established and much progress has been made in utilising risk modelling tools and supporting data to develop new information on risk for some hazards. Significant further work is required to reach an understanding of all hazards risks nationally.

Data package relates to tsunami modelling outputs that were used for the Catastrophic Working Group. This data relates is the underlying model development.

This project aims to improve the estimation of tropical cyclone risk in the Australian region by employing a numerical simulation approach based on a climate model. Climate models are the main tools used for predicting the effects of climate change, but usually they have employed resolutions too coarse to simulate reliably smaller weather systems such as tropical cyclones. In this work, a regional climate model of unprecedented fine resolution (the CSIRO regional model CCAM) will be implemented over the Australian region and an improved estimate both of present-day and future tropical cyclone hazard will be made. When combined with the results of a tropical cyclone damage model, new estimates of the tropical cyclone risk to infrastructure in northern Australia will be obtained

Geoscience Australia (GA) embarked on the development of the National Exposure Information System (NEXIS) project in response to the Council of Australian Governments (COAG) reform commitment on Australia's ability to manage natural disasters and other emergencies. The COAG commitment was for the establishment of a nationally consistent system of data collection, research and analysis to ensure a sound knowledge base on natural disasters and disaster mitigation - (DOTARS 2002). NEXIS has also been identified as an important component for improving several projects of national interest within Geoscience Australia (GA). These include the Risk Analysis Methods Section (RAMS), Climate hazards and Risk Section (CHRS) and the Vulnerability Section (VS) which investigate natural and man-made risks and their impacts on the community. The NEXIS was developed by the Exposure Information Section (EIS), National Geographic Information Group (NGIG), formerly the Engineering, Economic and Exposure Project (E3P), Risk and Impact Analysis Group (RIAG), within Geoscience Australia. It has a key role to gather accurate and up-to-date exposure information about Australia's resident population and buildings. This information is used when calculating the risk from natural and man-made disasters in order to inform policy and operational decision makers of the impact on Australian communities. In order to understand the effects a natural or man-made disaster could have on a community we need to know as much as we can about the people and buildings that occupy that area. This includes information about: People: how many people will be affected and where they live Buildings: the type of construction materials used, the number of storeys, and age all contribute to how a building withstands damage Cost : how much will it cost to rebuild a house or replace contents if damaged This information is used to not only investigate physical impacts of a disaster, but also forms base information that is needed to help inform the socio-economic impacts, such as loss to the business community when impacted by severe cyclonic wind storms. The National Exposure Information System (NEXIS) aims to maintain building level detail for all residential, commercial and industrial building in Australia. NEXIS information is available at Local Government Are (LGA) & Statistical Local Area (SLA)

Climate change is expected to exacerbate a range of natural hazards in Australia leading to more severe community impacts in the future. There is a need to adapt to a changing hazard environment and increasing community exposure in regions most likely influenced by climate change. Through this paper GA develops a methodology for projecting Australian communities in a spatial sense into the future. The application of this methodology is demonstrated in a case study. In order to address the fact that the impacts of climate change are expected to be more evident in the second half of this century, this model was to extend beyond the 30 year limitation of finer scale population projections, dwelling projections and development plans.

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) and Geoscience Australia are developing a long-term partnership in order to better understand and reduce the risks associated with earthquake hazards in the Philippines. The current partnership is specifically designed to enhance the damage estimation capabilities of the Rapid Earthquake Damage Assessment System (REDAS) software, developed by PHIVOLCS. We have chosen Iloilo City, Western Visayas, as the pilot community to demonstrate our earthquake risk assessment - QuiveR (Quick Unified Inventory of Vulnerability and Exposure for REDAS) Any natural hazard risk assessment requires an understanding on the nature and vulnerability of the building stock in the region of interest. We have acquired two main datasets; 1) the Philippine National Statistics Office census data; and 2) the Iloilo City Assessors Office Data, each providing unique attributes on the nature of the building stock and socio-economic indicators for the city. Finally, to supplement and validate these data, we conducted building surveys within Iloilo City. Through this project, we have engaged with local structural engineering community which led to the development of a National Building Classification Schema and consensus-based vulnerability curves for key building types in the Philippines. Finally, we discuss how models from this engagement process have been incorporated into REDAS to enable risk calculations for scenario earthquakes near Iloilo City. Finally, we have demonstrated how detailed understanding of the building stock in a local community can assist with natural hazard risk assessments - not just for risk reduction and response activities for future earthquakes, but possibly for a range of natural hazards.

The impacts of climate change, including sea level rise and the increased frequency of storm surge events, will adversely affect infrastructure in a significant number of Australian coastal communities. In order to quantify this risk and develop suitable adaptation strategies, the Department of Climate Change and Energy Efficiency (DCCEE) commissioned the National Coastal Vulnerability Assessment (NCVA). With contributions from Geoscience Australia (GA) and the University of Tasmania, this first-pass national assessment has identified the extent and value of infrastructure that are potentially vulnerable to impacts of climate change. A number of fundamental national scale datasets underpinned the NCVA. A mid-resolution digital elevation model was used to model a series of sea level rise projections incorporating 1 in 100 year storm-tide estimates where available. The model outputs were overlain with a national coastal geomorphology dataset, titled the Smartline. The Smartline identified coastal landforms that are potentially unstable and may recede under the influence of rising sea level. These datasets were then overlain with Geoscience Australia's National Exposure Information System (NEXIS) to quantify the number and value of infrastructure elements (including residential and commercial buildings, roads and rail) potentially vulnerable to a range of sea-level rise and recession estimates for the year 2100.

Hydrometeorological events make up or contribute to a majority of disasters in Australia and around the world. Scientists expect climate change will accelerate the frequency and intensity of these events in the future. Information on the location and characteristics of the built and social environment combined with hazard modelling and spatial analysis can facilitate the identification of buildings, people and infrastructure exposed to a particular natural hazard event. This information informs evidence based decision making and future planning to aid in the preparedness, response and recovery to severe hazard events. In Australia, the National Exposure Information System (NEXIS) is a significant national project being undertaken by Geoscience Australia (GA). In 2006 GA embarked on the development of NEXIS in response to the Council of Australian Governments (COAG) reform commitment on Australian's ability to manage natural disasters and other emergencies. The COAG commitment called for the establishment of a 'nationally consistent system of data collection, research and analysis to ensure a sound knowledge base on natural disasters and disaster mitigation' (DOTARS 2002). NEXIS database contains information on buildings, people, businesses and infrastructure and is derived from publicly available demographic, structural, economic and statistical data. Exposure profiles contain information on: building type, size, construction materials, age, replacement costs and population demographics for all residential, commercial and industrial buildings in Australia. Aggregated exposure information underpins risk assessment, emergency management, climate change adaptation, urban planning, insurance industry and research to help assist evidence based decision making. NEXIS development and operationalisation is crucial to support the decision makers and underpins community safety, emergency management and disaster risk reduction initiatives Australia This paper will discuss the development of NEXIS and its application in several national projects with the Department of Climate Change Energy and Efficiency (DCCEE) in Australia and recent national disaster impacts assessments on: Queensland tropical cyclone Yasi, Victoria bushfires and the Queensland floods.
