Australian Iron & Steel

Australian Iron & Steel (AI&S) was an Australian iron and steel manufacturer formed in 1928 to succeed Hoskins Iron & Steel and finance the transfer and expansion of steelmaking from Lithgow to Port Kembla on the New South Wales coast. The company was created at a time when the Australian steel industry was being reorganized around larger, coastal works capable of receiving raw materials by sea and serving expanding domestic manufacturing and construction markets. AI&S was backed by the Hoskins family, the British engineering and steel interests Dorman Long and Baldwins, and the Australian coal and shipping company Howard Smith Limited. The Hoskins interests contributed the operating assets of the predecessor business, while Dorman Long and Baldwins contributed equipment and related assets. Howard Smith provided cash financing and became the company's shipping agent. Cecil Hoskins served as chairman, with his brother Arthur Sidney Hoskins also joining the board. The company's principal development was the Port Kembla works. By 1932, the plant produced bars, iron pipe, rails and plate, while further facilities—including a sheet mill, galvanising plant and improvements to the bar mill—were planned. The new works experienced technical and financial difficulties, however, and the company was unable to resolve them independently. In October 1935, BHP acquired all AI&S ordinary shares in exchange for 750,000 BHP ordinary shares. AI&S then continued as a wholly owned BHP subsidiary; the transaction did not initially include its preference shares. The post-merger company faced immediate financial and industrial challenges. Its half-year profit fell sharply in 1936 and later turned into a loss. A dispute over the dismissal of Port Kembla mill hand Norman Annable developed into a broader strike beginning in January 1936 and eventually involving more than 3,000 workers. BHP nevertheless expanded the works as international steel demand improved. Additional merchant-mill, blast-furnace, steel-furnace and billet-making capacity substantially increased output before the Second World War. During the war, Port Kembla became a strategically important Australian industrial site. Constraints on shipping and the danger posed to maritime supply routes encouraged the reopening of iron-ore quarries and railway connections in New South Wales so that the works could maintain blast-furnace operations. The plant also manufactured war matériel, including components for 25-pounder guns. AI&S remained the corporate name associated with the Port Kembla integrated steelworks for much of the post-war period, although control rested with BHP. The subsidiary also operated facilities at Kwinana in Western Australia, including a rolling mill opened in 1956 and a blast furnace that operated from 1968 to 1982. Plans for a fully integrated Kwinana works were curtailed by global steel overcapacity. AI&S preference shares continued to trade until 1959, when they were converted into BHP ordinary shares under an accepted BHP offer. The AI&S corporate identity is now historical rather than an active independent brand. The Port Kembla steelmaking complex continued through later BHP structures and is associated with BlueScope's Australian steel operations. AI&S's lasting significance lies in its role in creating the Port Kembla works, one of Australia's major integrated steelmaking sites, and in the consolidation of Australian steel production under BHP.

Australian Iron & Steel was incorporated in 1928 as the successor to Hoskins Iron & Steel. Its formation was closely tied to the decision to move major steelmaking and rolling operations from Lithgow to Port Kembla, a coastal location better suited to shipping raw materials and finished products. The new enterprise required substantial capital, and its ownership combined the Hoskins family with British industrial companies Dorman Long and Baldwins and Australian coal and shipping company Howard Smith Limited. The ownership structure reflected the assets and financing each participant brought to the venture. The Hoskins and Dorman Long interests received ordinary shares for contributed assets, while Baldwins received shares partly in exchange for obsolete rolling-mill equipment that was dismantled at its Margam works and reinstalled at Port Kembla. Howard Smith and the preference shareholders supplied cash, and Howard Smith became AI&S's shipping agent. Cecil Hoskins became chairman and Arthur Sidney Hoskins joined the board. The company issued additional ordinary shares in 1929 and invested in Southern Portland Cement and Southern Blue Metal Quarries. The first Port Kembla works produced bars, iron pipe, rails and plate by 1932. AI&S also planned a sheet mill, galvanising plant and bar-mill modifications. The new facilities proved difficult to operate and placed pressure on the company's finances. In October 1935, BHP acquired all AI&S ordinary shares in return for 750,000 BHP ordinary shares. AI&S became a BHP subsidiary, although its preference shares were not included in the initial merger. BHP changed the subsidiary's board and appointed Harold Darling as chairman. The company's financial position remained difficult: it reported a substantial fall in half-year profit in March 1936 and a half-year loss later that year. The sheet mill was transferred to John Lysaght in April 1936, where it was subsequently operated successfully. Labour relations also deteriorated. A dispute over the dismissal of mill hand Norman Annable after he refused overtime developed into a wider strike over employment conditions. The stoppage began in January 1936 and continued until the end of March, eventually involving more than 3,000 Port Kembla workers. Improving international steel demand led BHP to expand Port Kembla from 1937. A second merchant mill, another blast furnace and a third steel furnace were added, followed by a billet mill. These projects approximately doubled the works' capacity compared with the period before the merger. The timing was important because the steelworks became central to Australia's industrial and military production during the Second World War. Shipping constraints and the threat of attacks on maritime routes encouraged the reopening of iron-ore quarries and railway infrastructure in New South Wales, including the former Hoskins quarry at Cadia and another quarry at Breadalbane. Port Kembla supplied military production, including components for 25-pounder guns. After the war, AI&S continued as the name of the BHP subsidiary operating the Port Kembla integrated works. It also expanded beyond New South Wales. A rolling mill began operating at Kwinana in Western Australia in 1956, and a blast furnace operated there from 1968 until 1982. Kwinana had originally been intended to become a second integrated steelworks, but international overcapacity undermined the larger development plan. The AI&S preference shares remained a long-running financial obligation for BHP because of their relatively high distribution rate. In 1959, shareholders accepted BHP's offer to convert the preference shares into ordinary BHP shares, ending their separate stock-market existence. The AI&S corporate entity and name subsequently lost their independent significance as the Port Kembla operations were carried through later BHP corporate arrangements. The steelworks are now associated with BlueScope. AI&S is therefore best understood as a historical Australian steel company and industrial identity whose principal legacy is the development of Port Kembla as a major integrated steelmaking centre.
