This assignment requires a comprehensive analysis of BHP Billiton's business operations, particularly their mining activities in Australia. Students need to examine the company's compliance with competition law, drawing from submissions made to the Competition Policy Review Panel. The analysis should also consider BHP Billiton's environmental impact, referencing agreements and reports on strategic assessments related to iron ore mining in the Pilbara region. Additionally, students are expected to explore other aspects of BHP Billiton's business, such as its divestments and involvement with domestic gas security in Western Australia.
