Oil refining and domestic consumption
Australia's oil refining sector plays a critical role in meeting the country's domestic energy demands, despite the nation being a net importer of crude oil. The primary fossil fuel refined in Australia is crude oil, which is processed into various petroleum products such as gasoline, diesel, jet fuel, and liquefied petroleum gas (LPG). Historically, Australia had a robust refining capacity, but over the past decade, several refineries have closed due to aging infrastructure, high operational costs, and competition from larger, more efficient refineries in the Asia-Pacific region. As of recent years, only four refineries remain operational: the Lytton Refinery in Queensland, the Altona Refinery in Victoria, the Kwinana Refinery in Western Australia, and the Geelong Refinery in Victoria. These facilities collectively process approximately 30-40% of Australia's crude oil requirements, with the remainder imported as refined products.
Domestic consumption of refined oil products in Australia is substantial, driven primarily by the transport sector, which accounts for over 90% of liquid fuel use. Gasoline and diesel are the most consumed products, powering cars, trucks, and other vehicles essential for both personal and commercial transportation. The industrial sector also relies on diesel for machinery and equipment, while jet fuel is critical for the aviation industry. LPG is another significant product, widely used for heating, cooking, and as an automotive fuel in rural areas. Despite efforts to transition to renewable energy sources, fossil fuels, particularly refined oil products, remain the backbone of Australia's energy mix due to their high energy density and existing infrastructure.
The decline in domestic refining capacity has raised concerns about energy security, as Australia has become increasingly reliant on imported refined products.

Coal seam gas development and impact
Coal seam gas (CSG), also known as coalbed methane, is a significant fossil fuel resource in Australia, particularly in Queensland and New South Wales. CSG is extracted from coal seams through a process that involves drilling wells and reducing the pressure in the coal seam to allow the gas to flow to the surface. This resource has become a critical component of Australia's energy mix, providing a domestically produced source of natural gas for electricity generation, industrial use, and export as liquefied natural gas (LNG). The development of CSG has been driven by its abundance and the need to diversify energy sources, but it has also sparked considerable debate due to its environmental and social impacts.
The extraction of CSG involves several stages, including exploration, drilling, hydraulic fracturing (fracking), and production. While CSG is often considered a cleaner-burning fuel compared to coal, its development raises concerns about water usage, land disturbance, and greenhouse gas emissions. One of the primary environmental impacts of CSG extraction is its effect on water resources. The process requires large volumes of water for drilling and fracking, which can strain local water supplies, particularly in arid and semi-arid regions. Additionally, there is a risk of contamination of groundwater and surface water from the chemicals used in fracking and the release of saline water co-produced with the gas. These issues have led to significant community opposition in areas where CSG development is proposed or underway.
Another critical impact of CSG development is its contribution to land degradation and habitat disruption. The construction of well pads, access roads, and pipelines can fragment ecosystems, disrupt wildlife habitats, and lead to soil erosion. In agricultural regions, CSG activities can interfere with farming practices, affecting soil quality and crop yields. Farmers and rural communities often express concerns about the long-term viability of their land and livelihoods in the face of CSG development. Furthermore, the industrialization of previously rural or natural landscapes can alter the character of these areas, impacting local communities and tourism.
Greenhouse gas emissions are another significant concern associated with CSG development. While natural gas is often promoted as a lower-emission alternative to coal, the extraction and processing of CSG can result in methane leaks, a potent greenhouse gas. Methane has a much higher global warming potential than carbon dioxide in the short term, meaning that even small leaks can significantly contribute to climate change. Additionally, the lifecycle emissions of CSG, including those from production, processing, and transportation, must be carefully managed to ensure that its use aligns with Australia's climate goals.
Despite these challenges, CSG development has provided economic benefits to Australia, particularly in regional areas. It has created jobs, stimulated local economies, and contributed to government revenues through royalties and taxes. The export of CSG as LNG has also bolstered Australia's trade balance, positioning the country as one of the world's largest LNG exporters. However, the industry must balance these economic benefits with the need to address environmental and social impacts through robust regulation, monitoring, and community engagement.
In conclusion, coal seam gas development plays a significant role in Australia's fossil fuel landscape, offering both opportunities and challenges. While it provides a valuable energy resource and economic benefits, its environmental and social impacts, particularly on water, land, and climate, require careful management. As Australia continues to navigate its energy transition, the sustainable development of CSG will be crucial to ensuring that its benefits are realized without compromising long-term environmental and community well-being.
