ONE case study of a transnational corporation involved in the chosen global economic activity, including its operations, spatial pattern, internal organisation, and role in the global economy

What this dot point is asking

NESA requires one TNC case study linked to your chosen economic activity. The TNC case study lets you trace operations, organisation, spatial pattern, supply chains, and impacts at corporate scale. BHP iron ore is the strongest Aussie TNC case because the data are public, the operations span the world's largest dry-bulk supply chain, and the impacts touch every dimension of the syllabus.

BHP at a glance

BHP Group is a Melbourne-headquartered global mining company, the world's largest by market capitalisation at around US$140 billion (2024). It was formed by the 2001 merger of Broken Hill Proprietary (Australian, founded 1885) and Billiton (UK-South African). Single primary listing on the Australian Securities Exchange since 2022. Around 80,000 employees globally.

BHP runs three core commodity portfolios: iron ore, copper, and metallurgical coal, plus a growing nickel and potash exposure. Iron ore is the single largest profit contributor, around 55 percent of group earnings.

The iron ore operations

Mines

Seven Pilbara mines plus the developing South Flank project make up Western Australia Iron Ore (WAIO):

• Mount Whaleback (Newman) - opened 1968, BHP's flagship and largest single-pit iron ore mine globally.
• Yandi (Yandicoogina) - large open-cut producer.
• Mining Area C - includes the South Flank development (delivered 2021, capacity 80 Mtpa).
• Jimblebar - automation pioneer; uses autonomous haul trucks.
• Eastern Ridge - feeds Newman.
• Newman - blending hub.
• South Flank - replaces the depleting Yandi capacity and lifted total WAIO capacity to around 290 Mtpa.

WAIO produced 257 Mt of iron ore in FY2024.

Rail and port

A privately owned, vertically integrated rail-port system. Around 1,000 km of heavy-haul railway connects the inland mines to Port Hedland. BHP runs around 200 dedicated locomotives, with autonomous trains operating since 2019.

Port Hedland is the world's largest tonnage bulk export port. BHP exports through Nelson Point and Finucane Island terminals, with around 615 Mt total Port Hedland throughput in 2023 (BHP plus other operators).

Shipping and marketing

A marketing hub in Singapore manages contracts, shipping logistics, and pricing for global customers. Cape-size dry-bulk carriers (typically 180,000-220,000 dwt) make the 7-12 day voyage to Chinese ports including Qingdao, Caofeidian, and Bayuquan.

Spatial pattern

BHP iron ore is one of the most spatially concentrated supply chains in global commodities. The activity is anchored to:

• Production. A 200 km by 100 km area of the Pilbara in Western Australia.
• Logistics. A 1,000 km rail spine and a single dominant port.
• Marketing. A Singapore office with currency, tax, and proximity advantages.
• Consumption. A 4,000-5,000 km shipping route to north-east Asian steel mills.

The concentration is by design. Mining is capital-intensive, infrastructure-intensive, and benefits from co-location and scale.

Internal organisation

BHP runs a global functional structure under a CEO (currently Mike Henry, 2020-present). Iron ore is part of the Minerals Australia portfolio under an Asset President, who reports to a CFO and a board.

The 2022 unification of BHP's London and Sydney listings simplified governance and capital management. The corporate strategy emphasises the so-called future-facing commodities (copper, nickel, potash) over thermal coal, which was divested via demerger (South32, 2015) and asset sales.

Role in the global economy

BHP iron ore contributes to:

• Australian export earnings. Iron ore is Australia's largest export by value at around $138 billion in 2022-23. BHP contributes around a quarter of that.
• Australian tax revenue. BHP paid around $9 billion in Australian taxes and royalties in FY2024.
• WA state revenue. Iron ore royalties were around $7 billion in 2023-24, the largest single state revenue source for Western Australia.
• Global steel supply. Around 70 percent of seaborne iron ore goes to China, where it underpins around 50 percent of global steel production and the construction sector that supports it.

Ecological and social dimensions

Direct environmental footprint

• Land disturbance. Around 30,000 ha of Pilbara mine footprint across BHP's iron ore operations.
• Water use. Around 25 GL of process and dust suppression water per year, much from groundwater.
• Direct emissions. Around 8.5 Mt CO2-equivalent in FY2024, mainly from diesel use in trucks and processing.

Scope 3 emissions

Around 380 Mt CO2-equivalent per year associated with customer use of BHP iron ore in steelmaking. This is more than 10 times BHP's own direct emissions and is the principal climate impact of the iron ore business.

Indigenous engagement

BHP operates on the traditional lands of multiple Aboriginal groups including the Banjima, Nyiyaparli, Yindjibarndi, Kariyarra, and Martu peoples. Indigenous Land Use Agreements (ILUAs) govern access and royalties. After the 2020 Juukan Gorge destruction by competitor Rio Tinto, BHP paused 40-plus mine plans pending heritage review and committed to new Indigenous heritage protocols.

Local and regional impacts

The Pilbara mining workforce drives a fly-in-fly-out (FIFO) economy. Port Hedland has a permanent population of around 16,000 but mining services bring transient populations to 25,000-plus. Housing affordability, public health, and Indigenous wellbeing in Port Hedland have been long-standing concerns.

Climate strategy

BHP committed (2020) to net-zero operational (Scope 1 and 2) emissions by 2050, with a 30 percent reduction by 2030. Customer-emissions (Scope 3) targets are softer: a 30 percent reduction in steelmaking customer emissions intensity by 2030, contingent on customer technology change. Hydrogen direct-reduction steel-making (HBI plus green hydrogen) is the long-term decarbonisation pathway.

Why BHP iron ore works as your case study

The data are public (annual report, ASX disclosures, BREE/AME reports), the operations span every syllabus dimension (extraction, transport, marketing, consumption), the impacts hit every scale (local Pilbara, national export earnings, global steel and emissions), and the management responses (Indigenous heritage, decarbonisation) connect the TNC topic to the wider HSC Geography syllabus.
