Airborne ultrafine particles in Australian cities. There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the c ....Airborne ultrafine particles in Australian cities. There is an acute deficiency of knowledge in Australia on urban airborne ultrafine particles, originating from transport and other anthropogenic sources, which pose significant health and environmental risks. The aim of this project is to address this deficiency by an extensive multi-city, cross-disciplinary study using state of the art instrumentation and data analytic techniques. The outcome will be an in depth, quantitative insight into the characteristics of the particles, their sources and spatial and temporal variation across different urban areas and time scales. Further, the impacts of changing fuels, vehicle technologies, and climate on future trends of the particles will be elucidated.Read moreRead less
How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environ ....How effective are environmental flows? Novel approaches for monitoring and assessing ecological responses to large-scale flow alteration. Australia has begun a multi-billion dollar program to return water to stressed rivers as environmental flows. However, during times of unprecedented water scarcity, such an investment in the environment can be controversial because the ecological benefits of released water are mostly poorly understood. This project will demonstrate the effectiveness of environmental flows, and promote greater understanding of the links between flow patterns and river health. The project will build upon existing knowledge to create a sound framework for planning, monitoring, and evaluation of environmental watering decisions across regional Australia, greatly improving our ability to sustainably manage rivers into the future.Read moreRead less

The project is expected to advance our capabilities to identify emerging hazards and understand factors that affect spatiotemporal trends in hazards across Australia. Moreover, in a world first, the project aims to assess c ....Understanding Australia by analysing wastewater during the Census 2021 . This project aims to utilise the Australian Census 2021, a unique opportunity to link exposure to chemical and biological hazards with catchment socio-demographic data via systematic wastewater analysis. The project is expected to advance our capabilities to identify emerging hazards and understand factors that affect spatiotemporal trends in hazards across Australia. Moreover, in a world first, the project aims to assess chemical fate on a national level by linking sales/use with fate and release from wastewater treatment plants and assess treatment efficiency at >100 plants around Australia. The project expects to provide insight for government, wastewater managers and industry into hazards that may affect environmental and human health.Read moreRead less
Best practice temperate woodland assessment, management and monitoring. This ARC proposal is central to the goals of National Research Priority #1 – An environmentally sustainable Australia. The loss of biodiversity in agricultural landscapes in rural Australia is a major social, economic and ecological issue. Australian governments and local communities invest considerable money restoring temperate woodlands in agricultural landscapes. However, there remains considerable uncertainty about the e ....Best practice temperate woodland assessment, management and monitoring. This ARC proposal is central to the goals of National Research Priority #1 – An environmentally sustainable Australia. The loss of biodiversity in agricultural landscapes in rural Australia is a major social, economic and ecological issue. Australian governments and local communities invest considerable money restoring temperate woodlands in agricultural landscapes. However, there remains considerable uncertainty about the effectiveness of this investment. This project will produce an unparalleled evidence-base for individuals and organisations that make long-term investments in these landscapes for conservation.Read moreRead less
E. coli as an indicator of faecal contamination in the Australian context. The goal of this research is to improve our ability to use Escherichia coli as an indicator of water quality by determining the extent to which non-faecal sources of E. coli contribute to coliform counts and to develop a method to differentiate non-faecal E. coli from those that are faecal derived.
New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ec ....New tools to detect ecological effects of contaminants in estuaries. Identifying risks to estuarine environments from pollutants is difficult for environmental managers, who must choose between laboratory toxicity testing that is precise, but hard to generalise to field situations, and more realistic field-based monitoring, which is expensive, with a high signal to noise ratio. New molecular techniques may provide more options. Metabolomics can provide insights into the health of animals, and ecogenomics offers a way to rapidly assess the composition of an ecological community. These techniques offer great promise, but they must be cross-validated against existing methods to derive the best ’toolbox’. Working with Melbourne Water and CSIRO the investigators aim to do this using demonstration estuaries in Victoria.Read moreRead less
Integrating satellite observations into environmental accounts. Accounting for biomass, water and ecosystem helps to manage and protect Australia's natural capital. Existing data provide only limited information, but this project will build on recent advances in satellite observation and model-data fusion technology to produce national accounts with unprecedented detail, for each year since 1990.
Diagnosing river health using invertebrate traits and DNA barcodes. Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline.

Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
A new-generation flood forecasting system using observations from space. Floods are dangerous and expensive, costing Australia more than any other cause of natural disaster. This project will use satellite measurements of soil moisture and rainfall along with computer models to improve the Bureau of Meteorology’s predictions of floods in rivers. Better flood forecasts will reduce costs and save lives.
Microbiology of a tropical creek impacted by sewage effluent: novel assessment using N-cycle functional markers and changes in community composition. Although most of Darwin Harbour has good water quality, there is much concern about local 'hot spots' where sewage has degraded ecosystem processes and values. As no bio-indicators of tropical marine water and sediment quality are known, the project will identify functional markers and microbial indicators of stress for integrated environmental mo ....Microbiology of a tropical creek impacted by sewage effluent: novel assessment using N-cycle functional markers and changes in community composition.
