Re: James Hardie Industries N.V.

Ladies and Gentlemen:

We have acted as income tax advisers to James Hardie Industries N.V., a public limited liability corporation registered in The Netherlands (referred to collectively as the “Company”), in connection with Australian income tax aspects of the Company’s proposed transaction(s) involving its redomicile to Ireland. These transactions include the registration of 102,000,000 ordinary shares, par value €0.59 per share (the “Securities”), of James Hardie Industries SE as a result of the transformation of the Company from a public limited liability corporation organized in The Netherlands (Naamloze Vennotschap (NV)) to a European Company (Societas Europaea (SE)) pursuant to the merger of a newly-formed subsidiary of the Company incorporated in Ireland with and into the Company. At your request, we are rendering our opinion concerning the material Australian income tax consequences of the Proposal (as defined in the Form F-4).

Facts, Representations, Assumptions and Materials Relied Upon

In the above capacity, we have reviewed the Registration Statement on Form F-4 (File No. 333-160177) that was filed by the Company on July 20, 2009, with the Securities and Exchange Commission under the Securities Act of 1933, relating to the Securities filed by the Company (the “Form F-4”) and such other documents as we have deemed necessary or appropriate in order to enable us to render the opinion below.

In our examination, we have assumed the legal capacity of all natural persons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, the authenticity of the originals of such copies and the validity and accuracy of the facts and representations concerning the Proposal (as defined in the Form F-4) that have come to our attention during our

engagement. In making our examination of executed documents, we have assumed that the parties thereto, including the Company, had and will have the power, corporate or other, to enter into and perform all obligations thereunder and also have assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties.

Applicable Authorities

Our opinion represents and is based upon our best judgment regarding the applicable provisions of the current Australian income tax legislation, case law and rulings issued by the Australian Tax Office (“ATO”), as in effect and available on the date of the Form F-4 and all of which are subject to change or differing interpretations, possibly with retroactive effect. A change in any of the authorities upon which our advice is based could affect our conclusions herein. There can be no assurance, moreover, that our opinion will be accepted by the ATO or, if challenged, by a court. Except as set forth herein, we express no opinion or view herein regarding the Australian income tax consequences of the Proposal or any other transaction related to the Proposal.

Our opinion is expressed as of the date hereof, and we are not under any obligation to supplement or revise our opinion to reflect any legal developments or factual matters arising subsequent to the date hereof or the impact of any information, document, certificate, record, statement, representation, covenant, or assumption relied upon herein that hereafter becomes incorrect or untrue. In addition, any changes to either the draft Form F-4 or the other documents referred to above could affect our conclusions herein.

We also advise you that: (i) this opinion is limited to the Australia tax statements actually addressed in this opinion; (ii) additional issues may exist that could affect the Australian income tax treatment of the Proposal or matter that is the subject of this opinion and this opinion does not consider or provide any advice or a conclusion with respect to any additional issues; and (iii) this opinion was not written and cannot be used by the Board of Directors of the Company or its Australian Shareholders (as defined in the Form F-4) for the purpose of avoiding penalties that may be imposed with respect to any Australian income tax issues outside the limited scope of this opinion.
