This report provides regional information on hazard and risks posed by landslides to communities within the southeast Queensland area. Research is based on the mapping of landslides that resulted from the January 1974 rainfall event. It firstly identifies areas of potential landslide using two methodologies and then undertakes a quantitative assessment of landslide hazard and risk.

In the following discussion the term 'landslides' is used in a very broad sense to include rock falls, topples, flows of solid material and slow movements of a few tens of centimeters per year.

The report is the fourth in a series of multi-hazard case studies by the Geoscience Australia Cities Project. It is a summary report which considers tropical cyclone, including severe wind and storm tide at Gladstone. It also provides an overview of the risks posed by severe thunderstorms, floods, landslides, heatwaves, bushfires and earthquakes. Produced in conjunction with the Bureau of Meteorology and in cooperation with Queensland Department of Emergency Services, Gladstone City Council and Calliope Shire Council.

This is a report describing a quantitative landslide risk assessment carried out in the Cairns area as part of the AGSO Cities Project. The study objective is to provide information on landslide types, conmunity vulnerability and risks to the Cairns City Council for planning and emergency management purposes. Using geological and geomorphological observations and historical information, a regional map of landslide hazards in the Cairns area has been produced. This map was entered into a geographic information system (GIS) containing comprehensive information on buildings, roads and demography.

The important role of information management in improving baseline data for natural hazards has been demonstrated through a collaborative pilot project between Geoscience Australia, Mineral Resources Tasmania and the University of Wollongong. The result is a 'virtual' landslide database that makes full use of diverse data across three levels of government and has enabled landslide data to be collated and accessed from a single source. Such a system establishes the foundation for a very powerful and coordinated information resource in Australia and provides a suitable basis for greater investment in data collection. This paper highlights the capacity to extend the methodology across all hazards and describes one solution in facilitating a sound knowledge base on natural disasters and disaster risk reduction.

The cost of landslide is underestimated in Australia because the impact and loss associated with these events are not readily reported or captured. There is no reliable source of data which highlights landslide cost to communities and explains who currently pays for the impacts and associated costs. The aim of this document is to investigate and analyse landslide costs within a Local Government Area (LGA) in order to highlight the varied landslide associated costs met by the local government, state traffic and rail authorities and the public. It is anticipated this may assist in developing a baseline awareness of the range of landslide costs that are experienced at a local level in Australia. Local government authorities across Australia are required to manage and mitigate landslide hazards. The Illawarra region of New South Wales (NSW) is one example of an area in Australia continuously affected by slope failure, often resulting in damage to property or infrastructure as well as occasional injuries and fatalities. Landslide losses are described for the region of Wollongong in NSW using a series of case studies to highlight the different types of landslide cost met by different parties, the variations in the landslide types that occur and the different cost components arising from them. This approach was chosen due to variations across the quality, availability and consistency of data. It was found that many generic natural hazard cost models are inappropriate for determining landslide costs because of the differences in the types of landslide movement and damage. Further work is recommended to develop a cost data model suitable for capturing consistent landslide cost data. Better quantification of landslide cost is essential to allow comparisons to be made with other natural hazard events at appropriate levels. This may allow for more informed policy development and decision making across all levels.

It is impractical for a single agency in Australia to hold responsibility for maintaining a national landslide database. Geoscience Australia has successfully demonstrated the benefits of adopting information management strategies as one solution in bringing local, regional and national scale landslide data together. In the first time that networked service oriented interoperability has been applied to a natural hazards domain, Australia now has an up-to-date central landslide database that makes full use of diverse data across three levels of government . The approach is centred upon a 'common data model' that addresses aspects of landslides captured by different agencies. The methodology brings four distinct components together: a landslide application schema; a landslide domain model; web service implementations and a user interface. Sharing and exchanging data more efficiently through an interoperable approach ensures that full value is made of available information, and that responsibility for collecting and maintaining this data is shared across all agencies. Specific-purpose data not only continues to serve the needs of individual database custodians, but also now serves a broader need. Such a system establishes the foundation for a very powerful and coordinated information resource in Australia through its ability to collate and characterise large volumes of information, and provides a suitable basis for greater investment in data collection. At a minimum the pilot project provides Australia with a framework for a centralised national landslide inventory, which can connect other available landslide databases. There is also considerable capacity for this approach to provide State Governments with a simple way to compile and maintain their own state-wide databases, and to extend the approach across other natural hazard databases and integrate data from other domains.

Slope failures with associated submarine slides, sediment accumulation along contourite drifts and focus seepage features have been interpreted from new sub-bottom profiler, multibeam bathymetry, side-scan sonar, echo-sounder data together with geochemical analyses of sediment samples along the continental slope off Western Australia. The processes recognised show the implication of slope instability and hydrocarbon seepage in shaping the continental slope geomorphology. The spatial correlation between regional seafloor features and reactivation of pre-existing faults suggests tectonics and seismic activity being the main potential triggering parameters for slope processes offshore northern Perth Basin. Geomechanical models have been used to test potential up-fault leakage using the present-day stress field and the results correlate with the seepage features observed in the study area. The marine survey results provide additional support for the presence of an active petroleum system in the northern Perth Basin; and combined with geomechanical models, the study helps reducing petroleum exploration and geohazards riks.
