The research utilised a motivation-opportunity-ability (MOA)-based conceptual model and market segmentation, identifying discrete segments within this population with regards to their attitudes to solar PV adoption and informing solar PV adoption interventions tailored to each. Design/methodology/approach: The research utilised a tailored survey distributed to strata property owners. To identify segments within the resulting 547-respondent sample, latent class analysis and k-means cluster analysis were performed. Findings: Data analysis revealed three discrete segments within this sample: “Frustrated Advocates”, who are highly supportive of strata solar but are less likely to consider it feasible for their particular strata scheme and who might respond to an ongoing collaborative intervention; “Passive Supporters”, who are more confident that strata solar would be feasible for their scheme but less enthusiastic in their personal support; and “Older Avoiders”, who are indifferent to strata solar in principle, unwilling to support it in practice, and who might require a carrot-and-stick approach that recognises their actual motivations. Research limitations/implications: The research does not test interventions targeting the identified segments. However, its findings can inform tailored interventions and subsequent case studies, and influence broader research into multi-stakeholder decision-making. Practical implications: This article proposes intervention strategies based on the segments' identified characteristics, to encourage and support adoption of solar PV in existing strata properties. Social implications: This article could help strata property owners and their tenants to access an important form of renewable energy. Originality/value: Through the application of an MOA-based model, this article enhances extant literature by enabling the conceptualisation of the directly relevant factors facing strata property owners seeking to adopt solar PV, particularly the need for collective approval from diverse stakeholders, and demonstrates how a segmentation-based methodology can provide robust findings with regards to their resulting attitudes. 2025-06-03T00:00:00Z http://hdl.handle.net/10453/194461 Title: Potential for a circular economy for sustainable large-scale renewable energy systems Authors: Pham, L; Kutay, C; James, G Abstract: The renewable energy industry has been in rapid progression to reduce carbon emissions to net zero by 2050. In this process, we cannot ignore the inevitable and continual decommissioning of a multitude of generation and transmission systems at their end-of-life, leading to a very large mass of waste being produced. With renewable generator lifespans ranging between 20-30 years, there is a limited period to develop a plan to re-introduce materials from these systems into future projects. This paper aims to discuss the status of our renewable energy market and the material available for re-use. This review relies on company and government reports, published work and other sources to establish the material that exists in our solar and wind farms, battery storage and transmission systems, and future changes expected. Then, we collate the options for recycling and the output of these existing recycling processes to separate and reuse the materials collected. There is a significant overlap in material across the generation and transmission networks which could be introduced into the circular economy through mass processing. At present some of this already have proposed uses, but most still goes to landfill, removing them from the circular process we aim to achieve. This research highlights the difficulty in achieving sustainability aspect of the renewable energy industry and some opportunities for introducing all material into the circular economy. This problem is handled for the energy industry and policy makers as well as encouraging those in recycling to take up this challenge. 2025-06-30T00:00:00Z http://hdl.handle.net/10453/194440 Title: From 3Ps to 6Rs: Urban Water and Wastewater Policies Influencing Circularity in the Built Environment in Australia Authors: Gajanayake, A; Karunasena, G; Paul, R Abstract: Wastewater systems in Australia are designed to efficiently transport the 3Ps (Poo, Pee and Paper) from households for treatment and safe disposal. With increasing water shortages, government policies are focusing on alternative sources of water such as recycled water to reduce freshwater demand and Circular Economy (CE) adoption. This chapter examines Australia's water and wastewater policies to assess how they incorporate the 6Rs (Rethink, Reduce, Remove, Reuse, Recycle and Recover) of circular economy strategies into the built environment. The analysis reveals that most of the policies focus on the use of recycled water for non-potable purposes and there is very limited use of recycled water in construction and built environment when this sector is responsible for 15–20% of the total freshwater use in Australia. The major challenges to achieving circularity in the water system are inconsistent regulations on water uses, conventional water and wastewater management systems that impede the utilisation of recycled water, lack of effective education and training among the construction practitioners and absence of metrics and tools to quantify the benefits. Given the economic focus of the construction and built environment sector, adequate attention is needed to address these challenges while developing and implementing water and wastewater policies. 2025-01-01T00:00:00Z http://hdl.handle.net/10453/194404 Title: Australia Authors: Austin, G Abstract: Australia has served as an international partner for Western security and intelligence interests for over a century, even before its national independence in 1901. It sent troops to fight with the British Empire in South Africa in 1889 and with the colonial powers, including the US, in the Boxer rebellion in China in 1900. This positioning of Australia was strengthened significantly since then by alliances with the US and the UK in two world wars, especially against Japan from 1941 to 1945, and by Australia s subsequent participation in most US-led foreign wars (Korea, Vietnam, Iraq and Afghanistan). Australia has partnered closely with the US in strategic competition with China, including in cyberspace, since at least 2011. As a result, over eight decades, Australia has become ever more deeply engaged in the most powerful cyber military and intelligence alliance in the world-the Five Eyes. This position was further transformed and strengthened in 2021 under the auspices of the AUKUS agreement. At the same time, new forms of multilateral cyber diplomacy with a hard security focus affecting Australia began to emerge, for example, with Ukraine, within NATO, and with major Indo-Pacific powers apart from China. These hard security interests of Australia in cyberspace have now pushed into the shade what had become a creditable level of international citizenship in support of the development of cyber norms within the framework of the United Nations and other multilateral settings. The main policy challenge for Australia now is to reconcile different strands of international cyber policy to secure its basic needs national defence, economic prosperity and domestic human security-while contributing to the good order of the region and the world. 2025-01-01T00:00:00Z
