South-eastern Australia Surface Geochemistry II: Light Hydrocarbon Geochemistry in Bottom-waters of the Gippsland Basin, Eastern Otway Basin, Torquay Sub-Basin and the Durroon Sub-Basin Vols 1 and 2

The Bureau of Mineral Resources (BMR) collected 1430 line-km of bottom-water
Direct Hydrocarbon Detection (DHD) data during a survey aboard R.V. Rig Seismic in
the Durroon Sub-basin, the Otway Basin, the Torquay Sub-basin, and the Gippsland
Basin, during late September and early October of 1991.
No significant bottom-water anomalies were detected in the Durroon Sub-basin.
Anomalous concentrations of light C2+ hydrocarbons were detected in the eastern
Otway Basin. The anomalies were not extensive, comprising only a few data points
representing a few kilometres in extent. One anomaly (of methane, ethane and
propane) was accompanied by high levels of the biogenic hydrocarbons, ethylene and
propylene, suggesting in-situ biogenic activity in the water column. However,
anomalous concentrations of C7 and C8 hydrocarbons were also found here and at
three other locations, and are from an unknown 'source'.
A weak bottom-water anomaly was detected in the Torquay Sub-basin in the same
location as an anomaly detected during an earlier survey (Rig Seismic Survey 89), two
years previously. The weakness of the anomaly prevents a confident interpretation of
the potential 'source' of the hydrocarbon anomaly, but the data suggests it is derived
from a gas/condensate, or dry thermogenic gas 'source'.
Several strong bottom-water anomalies were detected in the Gippsland Basin. Bottomwater
anomalies were found near the Sunfish and Tuna oil/gas accumulations, in
similar locations to anomalies found on Rig Seismic Survey 89, two years earlier.
However, another previously-detected anomaly (near Barracouta) was not reproduced.
Additional anomalies were found near Flathead, and to the west of Wahoo. The
anomaly west of Wahoo was weak and in a similar area to that detected on Survey 89.
The composition of most bottom-water hydrocarbon anomalies in the Gippsland Basin
are indicative of a liquid-prone hydrocarbon 'source', while one anomaly in the
northern sector of the survey area is indicative of a gas/condensate 'source'.

Queensland State Earthquake Risk Assessment

In 2017 Queensland Fire and Emergency Services (QFES) completed the State Natural Hazard Risk Assessment which evaluated the risks presented by seven in-scope natural hazards. The risks presented by earthquakes were evaluated as part of this assessment in broad terms. The assessment highlighted a number of key vulnerabilities and risks presented by earthquakes to the communities of Queensland requiring further analysis.
As QFES matures the Queensland Emergency Risk Management Framework (QERMF) by working with Local and District Disaster Management Groups (LDMGs/DDMGs), opportunities have arisen whereby QFES, in collaboration with relevant Federal and State Government and industry partners, are in a position to provide State-level support to LDMGs and DDMGs, through the development of in-depth risk assessments.
The State Natural Hazard Risk Assessment 2017 and the State Disaster Management Plan 2018 note that the QERMF, as the endorsed methodology for the assessment of disaster related risk, is intended to:
• Provide consistent guidance in understanding disaster risk that acts as a conduit for publicly available risk information. This approach assists in establishing and implementing a framework for collaboration and sharing of information in disaster risk management, including risk informed disaster risk reduction strategies and plans.
• Encourage holistic risk assessments that provide an understanding of the many different dimensions of disaster risk (hazards, exposures, vulnerabilities, capability and capacities). The assessments include diverse types of direct and indirect impacts of disaster, such as physical, social, economic, environmental and institutional.
The assessment and its intended audience
This risk assessment was developed using the QERMF to undertake a scenario-based analysis of Queensland’s earthquake risk.
It is intended to complement and support LDMGs and DDMGs in the completion of their risk-based disaster management plans. The development of the State Earthquake Risk Assessment 2018 was supported by Geoscience Australia (GA) through the provision of expert advice, relevant spatial datasets and the development of the scenarios used through this assessment.
Input has been sought from GA to help contextualise the findings of the National Seismic Hazard Assessment 2018 for Queensland.
Consultation with the University of Queensland has been sought to provide the ‘Queensland Context’, capitalising on the 80-year history of earthquake research and study undertaken by the university. A robust scientific basis enhances the assessment and enables disaster management groups to inform their local level planning.
Overall, the assessment and associated report seeks to complement and build upon existing Local and District earthquake risk assessments by providing updated and validated information relating to the changes in understanding Queensland’s earthquake potential.

Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the SA Exploration Initiative - Area A (A1-A7), SA., 1993 survey were acquired in 1992 by the SA Government, and consisted of 330915 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.
