Message from the Chief Executive OfficerFrom an environmental perspective, we maintained our progress in reducing the greenhouse intensity of our operations. Since establishing our current five-year reduction target to reduce the intensity of our production by five per cent, we have achieved a 10 per cent reduction. While water intensity reduced compared to last year, there is still an overall increase to date of five per cent against the 2001/02 baseline. In the year ahead, we will endeavour to improve performance in this area.We continued to meet our commitment to spend one per cent of our pre-tax profit on a three-year rolling average on community programs, contributing US$57.4 million to our local communities. In health we have been successful in reducing the number of new cases of occupational illness by 36 per cent when compared to the 2002/03 baseline.In June 2005 we welcomed WMC Resources Ltd to theBHP Billiton Group and look forward to reporting on the activities At BHP Billiton we recognise that integrating sound principlesof former WMC assets in future reports.

Our Performance – Socio-Economic The socio-economic aspects of our operations relate to how we manage our people and contribute to the economies within which we operate. Our priorities are: ·our relationships with our employees and contractors: development of our leaders; diversity, including indigenous employment; training; remuneration and other benefits of our employees ·our economic contribution to society: the payments we make to governments, including taxes and royalties, and the added value we provide as a result of our operations and their broader contributions through aspects such as payments to suppliers and employees. Employee Relations
Employee relations at BHP Billiton is the responsibility of local and business unit management. Each business is required to: ·implement employment arrangements that deliver outcomes consistent with the BHP Billiton Charter, Sustainable Development Policy and Guide to Business Conduct ·build open and productive relationships with employees and provide processes to address workplace issues in an equitable manner ·ensure that employees have the opportunity to develop skills that allow them to contribute to business success, and are recognised and rewarded for those results ·support fundamental human rights and freedom of association and ensure legal requirements governing employment are fully met ·respect local legislative requirements and other local standards and circumstances. Employee Profile During the year, the average number of permanent employees across the Company (including our owned and operated facilities as well as our share of unincorporated joint ventures) was around 36 470 compared to 35 070 reported in the previous period. This does not include approximately 3000 employees who have joined our Company as a result of the WMC acquisition. Regional Geographic Breakdown of Total Number of Employees 2004/05 South Africa 45%
[Graphic Appears Here] Rest of World 1% Australia and Asia 29% Europe (inc UK) 2% North America 7% South America 16% Diversity Approximately seven per cent of our Company’s management are women. In the year ending 30 June 2005, about 12 per cent of full-time employees at operated sites and offices were women. There were significant regional differences, with women representing about 9 per cent of full-time employees in Africa, 11 per cent in Australia, 18 per cent in North America and 7 per cent in South America. While there are currently no female members of the Board, the Company Secretary is a woman, as is the President of Gas and Power. The Company has identified some specific sites and countries where diversity issues are particularly sensitive. Examples of ongoing policies or programs undertaken to address employment diversity issues include employment equity in South Africa, which ultimately aims to achieve representation at all levels in our businesses consistent with the demographic profile of South Africa, and targeted indigenous employment programs in the Pilbara region of Australia (Iron Ore), the Northwest Territories in Canada (EKATI), and New Mexico in the United States (New Mexico Coal). Supply Our approach is to use local suppliers wherever possible. Over the reporting period, our distribution of spend with international suppliers reduced from 26 per cent in the previous year to 19 per cent in the current year, while distribution of spend with both local and national suppliers was at 27 per cent and 54 per cent respectively.

Policy in Action – Case Studies continued Aluminium CSG implements comprehensive occupational healthHealthmanagement strategy < Lung function testing at Mozal, Mozambique [Graphic Appears Here] Within our Aluminium Customer Sector Group (CSG), there are a number of health risks associated with the industry that must be controlled in order to ensure the health and safety of our workforce. To improve the identification and management of these risks in a comprehensive and systematic manner, an occupational health management program is being implemented. The key factor is promoting an environment that contributes to our employees and contractors being fit for work and fit for life. Our objectives are to adopt common standards for exposure assessment and medical evaluation; establish a baseline health risk profile; implement internationally referenced standards and methodologies; implement a strategy to minimise health and business risk; and establish a review process to ensure continuous improvement. As respiratory health issues are known to be associated with exposure to irritants in smelting, particular focus was given to this aspect during the initial phase. Progress to date includes increased awareness of respiratory health responsibilities; development and implementation of a standard protocol for respiratory health management; a peer review of the program protocol by international experts; an independent audit of the quality of lung capacity measurement practices; and a review of the respiratory protection program to allow improvement plans to be developed, which are currently being implemented. The next steps are to develop standard protocols for key health processes; progress implementation of the program; develop pitch exposure risk profiles, implement control strategies and investigate medical surveillance requirements; implement a medical screening process for contractors and develop contractor exposure profiles; continue to focus on the prevention of hearing loss by limiting noise exposure; and implement a strategy for injury case management and rehabilitation. We aim to assure the sustainability of the program through ongoing risk management, occupational health professional networking, and effective management and resourcing of the tasks within the program. [Graphic Appears Here] The BHP Billiton Fatal Risk Control Protocols (FRCPs) have been re-released with improvements, and a team of FRCP facilitators has been appointed to assist sites with their implementation. Their effective implementation forms an integral part of our safety strategy and the elimination of fatalities from our operations. In 2004, workshops were held in South Africa, South America and Australia to review the initial version of the FRCPs with the aim of improving their usability and ensuring the areas of risk were being appropriately addressed. Recommendations led to the document wording being refined and the development of an additional FRCP on Lifting Operations. There are now ten Protocols, and the team of FRCP facilitators, each of whom is an expert in one of the ten key risk areas, is available to assist sites globally with their implementation. A toolbox of communications materials is also available to support the re-release. Since the introduction of the FRCPs, a number of incidents have demonstrated the potential of the Protocols to help avoid fatalities, including: 12 • Optimum Colliery, South Africa – a bulldozer slid down an embankment and overturned. The protection afforded by the rollover safety frame and correct use of a three-point safety belt helped save the operator’s life. ·BHP Billiton Maatschappij, Suriname – a pick-up collided with a barricade and flipped onto its roof. The driver was saved from injury or death by wearing his safety belt correctly. ·Escondida copper mine, Chile – a contractor who fell from a work platform was saved from injury or death by his safety harness, which kept him suspended in the air. Each of our sites is required to achieve implementation of the additional requirements introduced in Issue 2 of the FRCPs by 30 June 2006. > BHP BILLITON SUSTAINABILITY SUMMARY REPORT 2005

[Graphic Appears Here] The use of water resources is of increasing importance. All sites with fresh water consumption greater than 500 megalitres have water management plans that require them to identify water sources, water consumption and opportunities to reduce water usage. In addition, we have set an aggregate Group target of 10 per cent reduction in fresh water consumption per unit of production by 30 June 2007. To help achieve these targets, many initiatives have been implemented. Carbon Steel Materials, South Walker Creek coal mine, Queensland, Australia Through the mine’s water conservation program, usage from its borefield supply source has been reduced from over 120 megalitres per month to less than 40 megalitres. The program is ongoing, with further investigation of on-site groundwater use. Base Metals, Antamina, Peru, South America Excess water from our operations has been used to transform 170 hectares of desert into a thriving plantation that includes threatened native tree species and is a shelter for birds, reptiles and mammals. The project has a potential life of another 18 years until Antamina’s closure plan is implemented. Aluminium, Boddington bauxite mine, Western Australia In 2003, Boddington implemented water conservation strategies with the aim of demonstrating ‘a measurable reduction in water consumption per unit of production within 12 months’. Consumption fell from 34.5 litres per tonne of aluminium produced to 31.43 litres, a 9 per cent reduction. The focus is now on cutting usage even further. Energy Coal, Cerrejón, Colombia, South America In 1999, 1.2 million cubic metres of stored water became acidified, resulting in a low pH that was outside discharge standards. Any spill could cause environmental harm. A pervious anaerobic filter was developed with limestone as the treatment medium. Over the next three years, the filter solution allowed the reuse of all the acid water. [Graphic Appears Here] When we began developing the Angostura oil and gas operation in the Mayaro/Guayaguayare region of Trinidad and Tobago, there was a sense of frustration in the local community as they felt the returns to the community from the energy sector had traditionally been too small. By consulting with the community to understand and address their needs and by initiating programs that help build local capabilities, strong relationships are being developed. The Mayaro/Guayaguayare region has historically been economically and socially marginalised. Though much of the country’s petroleum wealth is derived from the area, its economy and basic infrastructure are weak. There is widespread poverty, high unemployment and low academic performance. To earn the trust and respect of the community, we began by conducting bi-weekly meetings with community leaders. We also invited our subcontractors to answer questions, resolve issues and discuss employment needs. These meetings commenced during the construction phase of the project and continued for 20 consecutive months. The outcomes of the process have been significant. A commitment to local employment has led to an average of 60 per cent of our workforce being comprised of people from the area. During the peak labour period, the project hired 795 local people. To build local capacity and help raise the quality of life in the region, more than 61 community projects have been implemented, all based on local needs. Through this approach, our broad aims are to maximise local involvement in the Angostura operation, to help establish partnerships and other collaborations between international suppliers and resident organisations to support infrastructure development, and to enhance opportunities for local enterprises.

Policy in Action – Case Studies continued
[Graphic Appears Here] The Mozal aluminium smelter project in the Maputo province of southern Mozambique stands as a model for realising a sustainable long-term investment based on sound business principles that encompass the recognition and effective management of social and environmental responsibilities. The joint venture project was the country’s largest ever private investment. The first aluminium was cast in June 2000, and the first ingots were exported later that year. In August 2003, an expansion project to double production capacity was completed. From its earliest days, the project presented a number of significant challenges. The country was poor and hampered by fragile institutional structures. There were limited numbers of people with the training and skills required. Malaria and HIV/AIDS were prevalent. Infrastructure was poorly developed and there was limited local capacity to meet project needs. With the motto ‘Together we make a difference’ a wide-ranging program of health, safety, environment, community and socio- economic initiatives was put in place. Initiatives include: ·setting up programs focused on significant community matters, such as malaria prevention, HIV/AIDS, and maternal and child health ·the creation of the Mozal Community Development Trust (MCDT) to facilitate projects and programs to improve the quality of life of the surrounding communities. To date, some 200projects have been initiated by the MCDT, with expenditure exceeding US$10 million ·improving educational facilities in the region by providing funding towards the building of the first secondary educational facility in the vicinity of the mine; constructing a new primary school and supporting the training of teachers ·establishing various training programs and facilities to maximise the number of nationals in the workforce. Currently 93per cent of the 1105 permanent staff is Mozambican · developing a residential area within the vicinity of the smelter ·assisting local Small and Medium Enterprises to successfully compete for work and succeed in executing contracts without compromising Mozal’s HSEC principles, schedule or quality objectives. The commitment to ensure the sustainability of the business and its host communities has delivered significant achievements. Both project implementation phases were completed well under budget and ahead of schedule. Following good HSEC performance during phase 1, considerably better performance was recorded during phase 2 and the commencement of operations. Harmonious industrial relations are exemplified by the 16 million work hour phase 2 construction period, when no days were lost due to industrial action. Operational performance has exceeded design and is running at benchmark levels. The region and the country have benefited from needs-based infrastructure, social and community upliftment projects. • Students enjoy improved educational facilities at the Beluluane Primary School [Graphic Appears Here] • As part of its small business development, Mozal supports a local chicken raising enterprise The Mozal experience demonstrates that, when establishing a major resource project, it makes good business sense to invest not only in the venture but also in the host community. Primary business objectives do not have to be sacrificed. Risks can be mitigated through the collective efforts of the business, community, governments and their instrumentalities. 14 > BHP BILLITON SUSTAINABILITY SUMMARY REPORT 2005

[Graphic Appears Here] About BHP Billiton BHP Billiton is the world’s largest diversified resources company, with a portfolio of high-quality, long-life assets and a significant pipeline of growth projects. We have around 36 000 employees working in more than 100 operations and offices in 25 countries (see our BHP Billiton Locations Map). Headquartered in Melbourne, Australia, the Group has primary listings on the Australian and London Stock Exchanges. We have adopted a business model based on customer-oriented groupings called Customer Sector Groups (CSGs). This structure reflects our focus on the needs of our customers. Each CSG is a substantial business in its own right, and several are leaders in their respective fields. They have autonomy to optimise their businesses, with clear accountabilities. The CSGs are Aluminium, Base Metals, Carbon Steel Materials, Diamonds and Specialty Products, Energy Coal, Petroleum, and Stainless Steel Materials. Our key markets include downstream refiners and processors of raw materials, such as steelworks, smelters, petroleum refiners, power stations and diamond cutters. During the year we welcomed WMC Resources Ltd to the Group and look forward to reporting on the activities of former WMC assets in future reports. In line with the values expressed in our Charter, throughout our operations we have an overriding commitment to health, safety, environmental responsibility and sustainable development.
