The notes will be issued by BHP Billiton Finance (USA) and will be guaranteed by each of BHP Billiton Limited, an Australian limited company, and BHP Billiton Plc, an English public limited company.

BHP Billiton Finance (USA) will make payments of principal and interest on the notes, and the guarantors will make any payments coming due under the guarantees, free and clear of, and without withholding or deduction for, any Australian and United Kingdom taxes. In the event that payments of principal and interest on the notes or the guarantees become subject to Australian or United Kingdom withholding tax, BHP Billiton Finance (USA) or the guarantors, as applicable, will pay additional amounts so that the amount received by holders of notes after withholding tax will equal the amount that would have been received had no withholding tax been applicable, subject to some exceptions described in the attached prospectus.

In the event that changes in withholding tax law, treaties or interpretations require BHP Billiton Finance (USA) or the guarantors to pay these additional amounts, it may redeem the notes before their stated maturity at a price equal to 100% of their principal amount plus accrued interest to, but not including, the redemption date.

See “Risk Factors” beginning on page 1 of the attached prospectus for a discussion of material risks that you should consider before deciding whether to invest in the notes.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities, or passed upon the accuracy or adequacy of this prospectus supplement or the attached prospectus. Any representation to the contrary is a criminal offense.

Interest on the notes will accrue from and including the delivery date.

The underwriters are offering the notes subject to various conditions. The underwriters expect to deliver the notes in book-entry form through the facilities of The Depository Trust Company and its participants, including Euroclear and Clearstream, Luxembourg, on or about             , 2011.

Some of the information contained or incorporated by reference in this prospectus supplement may constitute “forward-looking statements” (within the meaning of Section 27A of the U.S. Securities Act of 1933 and Section 21E of the U.S. Securities Exchange Act of 1934), which are subject to various risks and uncertainties. These statements can be identified by the use of forward-looking terminology such as “intend,” “aim,” “project,” “anticipate,” “estimate,” “plan,” “believe” “expect,” “may,” “should,” “will,” “continue,” or other similar words. These statements discuss future expectations concerning the results of operations or financial condition or provide other forward-looking information. Our actual results, performance or achievements could be significantly different from the results expressed in, or implied by, those forward-looking statements.

Table of Contents

These forward-looking statements are not guarantees or predictions of future performance, and involve known and unknown risks, uncertainties and other factors, many of which are beyond our control, which may cause actual results to differ materially from those expressed in the statements contained in this prospectus. When considering these forward-looking statements, you should keep in mind the cautionary statements contained or incorporated by reference in this prospectus. These statements describe circumstances that could cause actual results to differ materially from those contained in any forward-looking statement.

For example, our future revenues from our operations, projects or mines described in this prospectus supplement and the attached prospectus (including the documents incorporated by reference herein) will be based, in part, upon the market price of the minerals, metals or petroleum produced, which may vary significantly from current levels. These variations, if materially adverse, may affect the timing or the feasibility of the development of a particular project, or the expansion of certain facilities or mines. Other factors that may affect the actual construction or production commencement dates, costs or production output and anticipated lives of operations, mines or facilities include our ability to profitably produce and transport the minerals, petroleum and/or metals extracted to applicable markets, the impact of foreign currency exchange rates on the market prices of the minerals, petroleum or metals we produce, activities of government authorities in some of the countries where we are exploring or developing these projects, facilities or mines, including increases in taxes, changes in environmental and other regulations and political uncertainty and other factors identified in the description of the risk factors above. We cannot assure you that our estimated economically recoverable reserve figures, closure or divestment of such operations or facilities, including associated costs, actual production or commencement dates, cost or production output, or anticipated lives of the projects, mines and facilities discussed in this prospectus will not differ materially from the statements contained in this prospectus.

Except as required by applicable regulations or by law, we do not undertake any obligation to publicly update or review any forward-looking statements, whether as a result of new information or future events or otherwise.

USE OF PROCEEDS

We anticipate the net proceeds from the issue and sale of the notes, after deducting underwriting discounts and commissions and our estimated expenses, will be approximately US$                                        . We intend to use the net proceeds from the offering of the notes for general corporate purposes, including repayment of commercial paper.

RATIO OF EARNINGS TO FIXED CHARGES

Shown below is the ratio of earnings to fixed charges for the BHP Billiton Group for the periods indicated.

We computed the ratio of earnings to fixed charges by dividing the amount of earnings by the amount of fixed charges. For the purposes of calculating this ratio, we have calculated earnings by adding pre-tax income before adjustment for minority interests in consolidated subsidiaries or income or loss from equity investees, fixed charges and distributed income of equity investees. Interest capitalized and the minority interest in pre-tax income of subsidiaries that have not incurred fixed charges were subtracted from the total of the added items. Fixed charges consist of interest costs, both expensed and capitalized, a reasonable approximation of the interest component of rental expense and pre-tax earnings required to cover any preferred stock dividend requirements.

SELECTED CONSOLIDATED FINANCIAL INFORMATION

The selected financial information for BHP Billiton reflects the combined operations of both BHP Billiton Limited and BHP Billiton Plc. BHP Billiton Limited and BHP Billiton Plc each reports, as its primary financial statements under the requirements of the Securities and Exchange Commission, the BHP Billiton Group’s consolidated financial statements prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and presented in US dollars.

The selected consolidated financial information for the BHP Billiton Group set forth below as at June 30, 2011 and 2010 and for the fiscal years ended June 30, 2011, 2010 and 2009 should be read in conjunction with and is qualified in its entirety by reference to the financial statements of the BHP Billiton Group for the corresponding periods and the accompanying notes thereto included in our Annual Report on Form 20-F for the fiscal year ended June 30, 2011 and incorporated by reference herein. The selected consolidated financial information for the BHP Billiton Group set forth below as at June 30, 2009, 2008 and 2007 and for the fiscal years ended June 30, 2008 and 2007 should be read in conjunction with and is qualified in its entirety by reference to the financial statements of the BHP Billiton Group for the corresponding periods and the accompanying notes thereto included in our Annual Reports on Form 20-F for the fiscal years ended June 30, 2009 and 2008, which are not incorporated by reference herein.

As permitted by AASB 2007-4 and IAS 31 “Interests in Joint Ventures” which became effective on July 1, 2007, the BHP Billiton Group has adopted the policy of recognizing its proportionate interests in the assets, liabilities, revenues and expenses of jointly controlled entities within each applicable line item of the financial statements. All such interests were previously recognized using the equity method. BHP Billiton Group believes the change in policy to proportionate consolidation of jointly controlled entities provides more relevant information about the financial performance and financial position of the BHP Billiton Group. AASB 2007-4 has been applied to the BHP Billiton Group annual financial statements for the fiscal years ended June 30, 2011, 2010, 2009 and 2008. As a result of this change in accounting policy, financial information as at and for the fiscal year ended June 30, 2007 was restated. See Note 1 to the consolidated financial statements included in our Annual Report on Form 20-F for the fiscal year ended June 30, 2008.

DESCRIPTION OF NOTES

The following description of the particular terms of the notes supplements the description of the general terms and provisions of the debt securities set forth in the attached prospectus. See “Description of Debt Securities That We May Offer” beginning on page 9 of the attached prospectus. To the extent the following description is inconsistent with that set forth in the attached prospectus, the following description replaces that in the attached prospectus.

General

The 20     notes will be issued in an aggregate principal amount of US$             and will mature on             , 20        . The 20    notes will be issued in an initial aggregate principal amount of US$    and will mature on    , 20    . The 20    notes will be issued in an initial aggregate principal amount of US$    and will mature on    , 20    . Book-entry interests in the notes will be issued in minimum denominations of US$2,000 and in integral multiples of US$1,000. The notes and guarantees will be governed by New York law.

The notes will be unsecured, unsubordinated indebtedness of BHP Billiton Finance (USA) Limited and will rank equally with all of the issuer’s other unsecured and unsubordinated indebtedness from time to time outstanding.

BHP Billiton Plc and BHP Billiton Limited each will unconditionally guarantee on an unsubordinated basis the due and punctual payment of interest on and principal of the notes, when and as any such payments become due and payable, whether at maturity, upon redemption or declaration of acceleration, or otherwise. The guarantees of the notes will be unsecured, unsubordinated obligations of BHP Billiton Plc and BHP Billiton Limited. The guarantees will rank equally with all other unsecured and unsubordinated indebtedness of BHP Billiton Plc and BHP Billiton Limited from time to time outstanding. Because BHP Billiton Plc and BHP Billiton Limited are holding companies, the notes will effectively be subordinated to any indebtedness of each of their subsidiaries.

The corporate trust office of the trustee in the City of New York is currently designated as the principal paying agent. We may at any time designate additional paying agents or rescind the designation of paying agents or approve a changing in the office through which any paying agent acts.

Payment of principal of and interest on the notes, so long as the notes are represented by global notes, as discussed below, will be made in immediately available funds. Beneficial interests in the global notes will trade in the same-day funds settlement system of The Depository Trust Company (DTC) and secondary market trading activity in such interests will therefore settle in same-day funds.

Interest

The 20    notes will bear interest at a rate of     % per annum, the 20     notes will bear interest at a rate of     % per annum and the 20    notes will bear interest at a rate of     % per annum, in each case, payable semi-annually in arrears on            and            of each year, commencing            , 2012. The regular record dates for payments of interest will be            and            . Interest on the notes will be computed on the basis of a 360-day year of twelve 30-day months.

Tax redemption

In the event of various tax law changes after the date of this prospectus supplement and other limited circumstances that would require us to pay additional amounts as described in the attached prospectus on page 20 under “Description of Debt Securities That We May Offer—Special Situations—Payment of Additional Amounts”, BHP Billiton Finance (USA), BHP Billiton Plc or BHP Billiton Limited may call all, but not less than all, of the notes for redemption. This means we may repay the notes prior to the stated maturity date of the notes. Our ability to redeem the notes is discussed in greater detail on page 17 of the attached prospectus under

S-14

Table of Contents

“Description of Debt Securities That We May Offer—Special Situations—Optional Tax Redemption”. If we call the notes as a result of such tax law changes, we must pay 100% of their principal amount. We will also pay the holders accrued interest if we have not otherwise paid interest through, but not including, the redemption date. Notes will stop bearing interest on the redemption date, even if the holders do not collect their money.

In either of the situations discussed above, we will give notice to DTC of any redemption we propose to make at least 30 days, but not more than 60 days, before the redemption date. Notice by DTC to participating institutions and by these participants to street name holders of indirect interests in the notes will be made according to arrangements among them and may be subject to statutory or regulatory requirements.

Defeasance and discharge

We may release ourselves from any payment or other obligations on the notes as described under “Description of Debt Securities That We May Offer—Defeasance and Covenant Defeasance—Defeasance and Discharge” on page 23 of the attached prospectus.

Trustee

The trustee under the indenture governing the notes is The Bank of New York Mellon. See “Description of Debt Securities That We May Offer” on page 9 in the attached prospectus for a description of the trustee’s duties generally and the procedures and remedies available to it in the event of a default under the notes.

UNDERWRITING

We have entered into an underwriting agreement dated November         , 2011 relating to the notes and the guarantees with the underwriters for the offering named below (for whom Barclays Capital Inc. and J.P. Morgan Securities LLC are acting as representatives). Subject to certain conditions, each underwriter has severally and not jointly agreed to purchase the principal amounts of the notes indicated in the following table at the price to investors less the underwriters’ discount set forth on the cover page of this prospectus supplement.

Barclays Capital Inc. and J.P. Morgan Securities LLC are the joint book-runners for the offering of the notes.

The underwriting agreement provides that the obligations of the several underwriters to purchase the notes included in this offering are subject to certain conditions.

The underwriters are obligated to purchase all the notes if they purchase any of the notes. The underwriting agreement does not provide for any increase in the aggregate principal amount of the notes being offered in this offering. However, we may issue further notes. See the section entitled “Description of Debt Securities That We May Offer—Default and Related Matters—Further Issues” on page 25 in the attached prospectus.

The issuer and the guarantors have jointly and severally agreed to indemnify the several underwriters against various liabilities, including liabilities under the Securities Act of 1933.

The distribution

We have been advised by the underwriters that they propose initially to offer the notes to the public at the prices to investors set forth on the cover page of this prospectus supplement. After the initial public offering, the prices to investors may be changed by the underwriters at their own initiative.

Purchasers of the notes may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country of purchase in addition to the prices to investors set forth on the cover page of this prospectus supplement.

No assurance can be given as to the liquidity of, or the trading markets for, the notes. We have been advised by the underwriters that they intend to make a market in the notes, but they are not obligated to do so and may discontinue such market-making at any time without notice.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include over-allotment, syndicate covering transactions and stabilizing transactions. Over- allotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the

S-16

Table of Contents

underwriters in this offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the notes. As a result, the prices of the notes may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue the activities at any time. These transactions may be effected in the over-the-counter market or otherwise.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts, will be approximately US$550,000.

The underwriters and their affiliates have performed certain investment banking and advisory and general financing and banking services for us from time to time for which they have received customary fees and expenses. In the ordinary course of business, the underwriters and their affiliates have engaged, and may in the future engage, in commercial banking or investment banking transactions with us and our affiliates or have performed, and may in the future perform, other financial services for all or any part of us and our affiliates.

No prospectus or other disclosure document in relation to the notes has been lodged with the Australian Securities and Investments Commission or the Australian Stock Exchange Limited. Each underwriter has represented and agreed that it:

unless, in the case of either (a) or (b):

Each of the underwriters has severally represented, warranted and agreed that:

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in the Relevant Member State (the

S-17

Table of Contents

Relevant Implementation Date) it has not made and will not make an offer of notes which are the subject of the offering contemplated by this prospectus supplement to the public in that Relevant Member State other than:

provided that no such offer of notes shall require the issuer or any guarantor to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

None of the issuer, the guarantors or the underwriters have authorized, nor do they authorize, the making of any offer of the notes in circumstances in which an obligation arises for the issuer, the guarantors or the underwriters to publish a prospectus for such offer.

For the purposes of this provision, the expression “offer of the notes to the public” in relation to any of the notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe the notes, as the same may be varied in that member state by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC (and amendments thereto, including the 2010 PD Amending Directive, to the extent implemented in the Relevant Member State), and includes any relevant implementing measure in each Relevant Member State and the expression 2010 PD Amending Directive means Directive 2010/73/EU.

Barclays Capital Inc. and J.P. Morgan Securities LLC have agreed, severally and not jointly, that they will ensure that the underwriters offer the notes (i) to at least 10 persons, each of whom is carrying on a business of providing finance or investing or dealing in securities in the course of operating in a financial market, and is not known or suspected to be an associate (as defined in section 128F(9) of the Income Tax Assessment Act 1936 of Australia (Australian Tax Act)) of any other persons to whom the offer is made by the underwriter under this section; or (ii) in such other manner as which satisfies section 128F(3) of the Australian Tax Act. Such offers will be made within 30 days of the relevant underwriter being unconditionally obliged to offer the notes for sale.

Each underwriter has represented and warranted that it is and will be acting as an underwriter in the course of carrying on a business of providing finance, or investing or dealing in securities in the course of operating in financial markets.

Each underwriter has represented and agreed that, in connection with the primary distribution of the notes, it will not (directly or indirectly) sell notes to any person if, at the time of such sale, the employees of the underwriter who are involved in making the offer, effecting the sale or otherwise directly involved in the sale knew or had reasonable grounds to suspect that, as a result of such sale, any notes (or an interest in any notes) was being, or would be, acquired (directly or indirectly) by an Offshore Associate (as defined below) other than in the capacity of a dealer, manager or underwriter in relation to the placement of those notes or in the capacity of a clearing house, custodian, funds manager or responsible entity of an Australian registered scheme. For the avoidance of doubt, if the relevant employees of an underwriter do not know, or do not have reasonable grounds to suspect, that a person is an associate of the issuer or one of the guarantors, nothing in this paragraph obliges that underwriter to make positive inquiries of that person to confirm that person is not an Offshore Associate. In this paragraph, “Offshore Associate” means an associate (as defined in section 128F(9) of the Australian Tax Act) of the issuer or one of the guarantors that is either a non-resident of Australia that does not acquire the notes in carrying on a business at or through a permanent establishment in Australia, or a resident of Australia that acquires the notes at or through a permanent establishment outside Australia.

The notes are offered in a global offering for sale in those jurisdictions in the United States, the European Economic Area, Australia and elsewhere where it is lawful to make such offers.
