under all relevant laws except the laws of the Relevant Jurisdiction;(k)

in all relevant jurisdictions (other than in the Relevant Jurisdictions). We confirm that the ASIC Searches

 (m)
    
    each party to a Document (other than the Australian Guarantors) was, or will be,
solvent within the meaning of section 95A of the Corporations Act at the time
of entering into each Document to which it is a party and immediately
thereafter;(n)
    
    other than in respect of the Australian Guarantors and the Collateral Trustee, that no party enters into any Documents in the capacity of a trustee of any trust or
settlement; and(o)
    
    no person has engaged or will engage in misleading or unconscionable conduct or is
or will be involved in or a party to any relevant transaction or any associated
activity in a manner or for a purpose not evident on the face of the Documents
which might render any Document or any relevant transaction or associated
activity in breach of any applicable law, void or voidable.
 The making of each of the assumptions indicates that we have assumed that each matter the
subject of each assumption is true and correct and complete in every particular. That we
have made an assumption in this opinion does not imply that we have made, nor are we
obliged to make, any independent investigation of, or enquiries to verify any assumption.
 We also note that any person is entitled to make the assumptions set out in section
129 of the Corporations Act in relation to dealings with each Australian Guarantor
unless, at the time of the dealing, that person knew or suspected that any such
assumption was incorrect. We have relied on the assumptions specified in section
129(2)-(8) of the Corporations Act and do not know or suspect that those assumptions are
incorrect.
 7.
    
    OpinionsSubject to our assumptions and qualifications set out in this opinion, we are of the

    each Australian Guarantor has the corporate power to enter into, and
perform its obligations under the Documents to which it is a party;(c)
    
    each Australian Guarantor has taken all necessary corporate action to
authorise the execution, delivery and performance of its obligations under the
Documents to which it is a party;

 (d)
    
    the Documents to which it is expressed to be a party have been validly
executed and (if in deed form) delivered by each Australian Guarantor; and(e)
    
    the execution and delivery by each Australian Guarantor of, and the
performance by it of its obligations under, each Document to which it is a party
does not and will not conflict with or breach;
 (i)
    
    its Constitution; or(ii)
    
    any law of the Relevant Jurisdictions applicable to companies generally.
 8.
    
    QualificationsThis opinion is subject to the following qualifications:
 (a)
    
    the expression enforceable means that the relevant obligations are of a
type that the courts in the Relevant Jurisdictions would ordinarily enforce and does
not mean that the obligations will necessarily be enforced in all circumstances in
accordance with their terms. In particular the enforceability of the
Documents and our opinions contained  in paragraph 7 are subject to matters that can include equitable remedies, statutes of limitations, laws
of bankruptcy, liquidation, insolvency, receivership, administration, reorganisation,
moratoria, court schemes, laws relating to insolvent transactions and
unfair loans (within the meaning of sections 588FC or 588FD
respectively of the Corporations Act) or similar laws affecting generally the enforcement of
creditors rights, fraud, duress or unreasonable or unconscionable conduct on the
part of another party or of a third person of which another party has actual or
constructive knowledge;(b)
    
    a court of a Relevant Jurisdiction may:
 (i)
    
    refuse to exercise jurisdiction in certain circumstances, including where
the court determines that there is a more suitable forum or that any
order made by the court would not be effective;(ii)
    
    stay actions on the grounds of oppression or vexation or if there are
proceedings in respect of the Documents in other
jurisdictions simultaneously on foot; and(iii)
    
    refuse to admit telephone recordings into evidence, notwithstanding the
parties to the action have agreed to their admissibility;
 (c)
    
    a court of the Relevant Jurisdictions will not give effect to a choice of
law to govern the Documents, an obligation to comply with foreign laws or a
submission to the jurisdiction of certain courts if to do so would be contrary to
public policy;(d)
    
    we express no opinion as to any obligation to negotiate in good faith or
any agreement to agree contained in any Document or any waiver of a statutory right;(e)
    
    a provision in a document that a certificate, statement or opinion of any
person will be conclusive and binding may be construed to mean only that such
certificate, statement or opinion will be or be received as prima facie evidence of
that fact;(f)
    
    a court in a Relevant Jurisdiction may not regard itself as having
jurisdiction to entertain any action relating to the Documents to the extent
that the Documents relate to property located outside that Relevant
Jurisdiction;

 (g)
    
    where any party to an agreement is required to make any payments on demand,
courts may require that that party be given a reasonable time after demand is
made on that party to comply with the demand before the creditor will be
permitted to realise or enforce the Documents for a failure to satisfy the
demand;(h)
    
    we express no opinion on any provision in the Documents requiring written
amendments and waivers, insofar as it suggests that oral or other
modifications, amendments or waivers could not be effectively agreed upon or
granted between or by the relevant parties; and(i)
    
    we express no opinion as to legislation in any Relevant Jurisdiction which has not
commenced, or if it has commenced, has not started to apply (including without
limitation, relevant provisions of the Personal Property Securities Act 2009
(Cth), the Personal Property Securities (Consequential Amendments) Act 2009
(Cth) and the Personal Property Securities (Corporations and Other Amendments)
Act 2010 (Cth)).
 9.
    
    GeneralWe hereby consent to the filing of this opinion as an exhibit to the Registration
Statement relating to the Notes and the Guarantee and to the use of our name under the
heading Legal Matters. In giving such consent, we do not admit that we are included in
the category of persons whose consent is required under section 7 of the Securities Act
1933 (USA) or the rules and regulations of the Securities and Exchange Commission (USA).This opinion is strictly limited to the matters stated in it and does not apply by
implication to other matters.
