You should rely only on information contained or incorporated by reference in this prospectus supplement, the accompanying prospectus and any
free writing prospectus with respect to the offering of the notes filed by us with the Securities and Exchange Commission, which we refer to as the SEC.
We have not, and the underwriters have not, authorized anyone to provide you with different or additional information. If anyone provides you with
different, additional or inconsistent information, you should not rely on it. You should assume that the information in this prospectus supplement, the
accompanying prospectus and any free writing prospectus with respect to the offering of the notes filed by us with the SEC and the documents
incorporated by reference herein and therein is only accurate as of the respective dates of such documents. Our business, financial condition, results of
operations and prospects may have changed since those dates.
We are offering to sell, and are seeking offers to buy, the notes only in jurisdictions where offers and sales of the notes are permitted. The
distribution of this prospectus supplement and the accompanying prospectus and the offering of the notes in certain jurisdictions may be restricted by
law. Persons outside the United States who come into possession of this prospectus supplement and the accompanying prospectus must inform
themselves about and observe any restrictions relating to the offering of the notes and the distribution of this prospectus supplement and the
accompanying prospectus outside the United States. This prospectus supplement and the accompanying prospectus do not constitute, and may not be
used in connection with, an offer to sell, or a solicitation of an offer to buy, any notes offered by this prospectus supplement and the accompanying
prospectus by any person in any jurisdiction in which it is unlawful for such person to make such an offer or solicitation.
Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Directive (as defined
below). The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any
retail investor in the European Economic Area ("EEA"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client
as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of
Directive 2002/92/EC (as amended, "IMD"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of
MiFID II; or (iii) not a qualified investor as defined in the Prospectus Directive. Consequently no key information document required by Regulation
(EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the notes or otherwise making them available to retail investors in the
EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful
under the PRIIPS Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in
any Member State of the EEA which has implemented the Prospectus Directive (each, a "Relevant Member State") will only be made to a legal entity
which is a qualified investor under the Prospectus Directive ("Qualified Investors"). Accordingly any person making or intending to make an offer in
that Relevant Member State of notes which are the subject of the offering contemplated in this prospectus supplement and the accompanying prospectus
may only do so with respect to Qualified Investors. Neither Westpac nor the underwriters have authorized, nor do they authorize, the making of any
offer of notes other than to Qualified Investors in the EEA. The expression "Prospectus Directive" means Directive 2003/71/EC (as amended, including
by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

Interest Payment Dates
Interest on the fixed rate notes will be payable semi-annually in arrears on May 15 and November 15 of each
year, subject in each case to the applicable business day convention set forth below, beginning on
November 15, 2018. Interest on the floating rate notes will be payable quarterly in arrears on February 15,
May 15, August 15 and November 15 of each year, subject in each case to the applicable business day
convention set forth below, beginning on August 15, 2018. Any payment of principal or interest with
respect to the fixed rate notes required to be made on an interest payment date that is not a business day in
New York, London and Sydney will be made on the next succeeding business day, and no interest will
accrue on that payment for the period from and after the interest payment date to the date of payment on the
next succeeding business day. If any floating rate interest payment date (as defined herein) would fall on a
day that is not a business day in New York, London and Sydney, other than the floating rate interest
payment date that is also the date of maturity for the floating rate notes, that floating rate interest payment
date will be postponed to the following day that is a business day, except if such next business day is in a
different month, in which case such floating rate interest payment date will be the immediately preceding
day that is a business day. If the date of maturity of the floating rate notes is not a business day, payment of
principal and interest on the floating rate notes will be made on the following day that is a business day and
no interest will accrue for the period from and after such date of maturity of the floating rate notes.
Ranking
The notes will be our direct, unconditional, unsubordinated and unsecured obligations and will rank, except
for certain debts required to be preferred by law, equally with all of our other unsecured and unsubordinated
obligations from time to time outstanding. For a description of debts preferred by law, see "Description of
the Notes--Ranking" in this prospectus supplement. The notes will rank senior to our subordinated
obligations, including any Subordinated Debt Securities described in the accompanying prospectus.
Redemption for Taxation Reasons
Subject to certain limitations, the senior indenture (as defined herein) provides that we will have the right to
redeem the 2020 fixed rate notes, the 2023 fixed rate notes, the 2020 floating rate notes and/or the 2023
floating rate notes, in each case in whole, but not in part, as described in the accompanying prospectus
under the heading "Description of the Debt Securities--Description of the Senior Debt Securities--
Redemption of Senior Debt Securities--Redemption for Taxation Reasons", with respect to the notes.

If we redeem the 2020 fixed rate notes, the 2023 fixed rate notes, the 2020 floating rate notes or the 2023
floating rate notes in these circumstances, the redemption price of each note redeemed will be equal to
100% of the principal amount of such note plus accrued and unpaid interest on such note to but excluding
the date of redemption.
