This project aims to explore how the visual appearance of warning messages influences internet users. It plans to conduct a randomised controlled experiment with naïve participants on a real-life website to test the effectiveness of messages designed to discourage viewers of legal ‘barely legal’ pornography. It is anticipated that results will assist policing efforts by indicating whether warnings can be used to dissuade first-time CEM viewers and whether differences exist between harm or deterrent-focused messages.Read moreRead less
Cosmic powerhouses: The birth, death, and legacy of black hole jets. This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies. The project will addres ....Cosmic powerhouses: The birth, death, and legacy of black hole jets. This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies. The project will address these questions using novel supercomputer models of black hole jets in realistic cosmological environments, then confront these predictions with new data from Square Kilometre Array (SKA) pathfinding radio telescopes. This will substantially enhance Australia’s leadership capacity in a strategically important area.Read moreRead less
Remote presence for guidance on physical tasks. This project aims to transform remote collaboration on physical tasks. Current systems for remote collaboration on physical tasks are not as effective as working face-to-face. This could be overcome by sharing non-verbal cues, designing systems to account for cultural issues, and using a new model of communication. This project will develop theories and interaction methods for remote guidance based on natural non-verbal communication cues and cultu ....Remote presence for guidance on physical tasks. This project aims to transform remote collaboration on physical tasks. Current systems for remote collaboration on physical tasks are not as effective as working face-to-face. This could be overcome by sharing non-verbal cues, designing systems to account for cultural issues, and using a new model of communication. This project will develop theories and interaction methods for remote guidance based on natural non-verbal communication cues and cultural issues. This project is expected to benefit industries with widely distributed multi-cultural workforces such as mining, defence and medicine.Read moreRead less
Are ocean storms impacting Australia becoming more severe? This project aims to improve our understanding of the severe ocean storms that impact Australia. The novel approach will make use of multiple decades of the background 'noise', recorded continuously by earthquake seismic observatories, to locate and analyse ocean storms through time and identify changes in storm tracks. An interdisciplinary interpretation will follow which combines the large body of new results from seismology with data ....Are ocean storms impacting Australia becoming more severe? This project aims to improve our understanding of the severe ocean storms that impact Australia. The novel approach will make use of multiple decades of the background 'noise', recorded continuously by earthquake seismic observatories, to locate and analyse ocean storms through time and identify changes in storm tracks. An interdisciplinary interpretation will follow which combines the large body of new results from seismology with data from oceanography and meteorology. Significant advancement in our knowledge of severe storms will benefit Australia by indicating whether such storms are becoming more severe or, alternatively, if storm patterns are shifting.Read moreRead less
Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine ....Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.Read moreRead less

Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less
Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire ....Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire risk and spread, trained and validated on a two-decade satellite fire record. The predictive ability of the model will be tested on the 2019/20 fire season to determine if novel drivers of fire can be identified, and the model itself will be operationalised into a novel short-to-mid term fire risk prediction tool.
