Oil and gas reserves
The table below details our oil, condensate, LPG and gas reserves, estimated at 30 June 2003, 30 June 2002 and 30 June 2001 with a reconciliation of the changes in each year. Our reserves have been calculated using the economic interest method and represent our net interest volumes after deduction of applicable royalty, fuel and flare volumes. Our reserves have been subjected to economic tests to demonstrate their commerciality under prices and costs existing at the time of the estimates. Our reserves include quantities of oil, condensate and LPG which will be produced under several production and risk-sharing arrangements that involve us in upstream risks and rewards but do not transfer ownership of the products to us. At 30 June 2003, approximately 19 per cent (2002: 17 per cent, 2001: 14 per cent) of proved developed and undeveloped oil, condensate and LPG reserves and nil (2002: nil, 2001: nil) of natural gas reserves are attributable to those arrangements. Our reserves also include volumes calculated by probabilistic aggregation of certain fields that share common infrastructure. These aggregation procedures result in enterprise-wide proved reserves volumes, which may not be realised upon divestment on an individual property basis.

50 Supplementary mineral resource and ore reserves information (unaudited)
The statement of Mineral Resources and Ore Reserves presented in this report has been produced in accordance with the Australasian Code for reporting of Mineral Resources and Ore Reserves, September 1999 (the 'JORC Code'). Commodity prices and exchange rates used to estimate the economic viability of reserves are based on September 2002, BHP Billiton long-term forecasts unless otherwise stated. The Ore Reserves tabulated are all held within existing, fully permitted mining tenements. The BHP Billiton Group's mineral leases are of sufficient duration (or convey a legal right to renew for sufficient duration) to enable all reserves on the leased properties to be mined in accordance with current production schedules.
The information in this report relating to Mineral Resources and Ore Reserves is based on information compiled by Competent Persons (as defined in the JORC code) or for operations located outside Australia by Recognised Mining Professionals, defined as a member of a recognised mining professional body. All Competent Persons and Recognised Mining Professionals have, at the time of reporting, sufficient experience relevant to the style of mineralisation and type of deposit under consideration and to the activity they are undertaking to qualify as a Competent Person as defined by the JORC Code. Each Competent Person consents to the inclusion in this Report of the matters based on their information in the form and context in which it appears.
All of the Mineral Resource and Ore Reserve figures presented are reported in 100 per cent terms, and represent estimates at 30 June 2003 (unless otherwise stated). All tonnes and grade information has been rounded; hence small differences may be present in the totals. All of the Mineral Resource information (unless otherwise stated) is inclusive of Mineral Resources that have been converted to Ore Reserves (i.e. Mineral Resources are not additional to Ore Reserves).
The information contained herein differs in certain respects from that reported to the US Securities and Exchange Commission (SEC) which is prepared with reference to the SEC's Industry Guide 7. BHP Billiton's US GAAP disclosures reflect the information reported to the SEC.
Ore Reserves and Mineral Resources are presented in the accompanying tables subdivided for each of the Customer Sector Groups.

(1) Worsley resource numbers are quoted on a dry basis; Competent Person is D Parmenter (MAIG).
(2) Suriname resource numbers are quoted on a dry basis; Competent Person is D L Butty (EuroGeol).
(3) Resource tonnages for MRN washed are quoted with nominal 5 per cent moisture; Competent Person is V J van der Riet (MAusIMM).
(4) Alumina as available alumina for Worsley and MRN; and total alumina for Lelydorp.
(5) MRN - Mineração Rio do Norte.
(6) The Worsley total resource increased by 15 Mt from the previous 2002 estimate; this is the net effect of new drilling, minor changes in cut-off grade and mining depletion during the year. Suriname resource changes are the result of mining depletion. The reduction in MRN crude and washed resource is due to mining depletion and the loss of resource due to environmental restrictions and selective mining.

(1) The Escondida deposit is a supergene-enriched porphyry copper deposit. Changes in the Mineral Resource reflect mining depletion. Stockpiled material above respective cut-off grades is included as Measured Resource. (2) The Pinto Valley Mineral Resource is based on the milling and flotation of copper sulphides from ore-grade rock and acid leaching and SXEW of copper from lower grade sulphide bearing rock. (3) BHP Copper North America ceased operations at the Robinson Mine site on 24 June 1999. |
(4) BHP Billiton holds a 99.9 per cent interest in Tintaya, an open pit copper mine in southern Peru. The remaining interest is held by Peruvian shareholders. (5) Cerro Colorado is a supergene-enriched porphyry copper deposit. (6) Antamina Resource is exclusive of Ore Reserves. (7) The Cannington Ag-Pb-Zn deposit is a Broken Hill Type (BHT) deposit located in the Eastern Succession of the Mt Isa inlier. Results from ongoing underground diamond drilling and geological interpretation have seen the upgrading of Inferred Resource to Indicated and Indicated to Measured. (8) %TCu - per cent total copper, %SCu - per cent soluble copper. |
(9) Competent Persons - Resources
|
(10) The Cerro Colorado total Mineral Resource has increased by 129 Mt from that quoted in 2002, this is due to additions and reclassification based on further drilling less resource depletion due to mining. The Tintaya sulphide and oxide Mineral Resources have been re-estimated with the inclusion of further drilling and changes to resource classification methods. Other changes in the Base Metals Customer Sector Group resource base are predominantly due to mining depletion. |

(4) No changes to the block model or the ore types were introduced in this declaration. Change in the Ore Reserves tonnages compared to the previous statement results from the depletion
of Ore Reserves through production, the application of a mining recovery factor to the stockpiled resources to generate stockpiled reserves and the reclassification of some probable oxide
reserves as mixed reserves or waste. The use of a variable cut-off grade strategy during the production period has also resulted in the reclassification of some sulphide ore into LG Float ore. LG Float ore extracted from the pit is stockpiled in the LG leach stockpile resulting in a reclassification to stockpiled LG leach resource. Measured Resource for Mixed ore has been
downgraded to Probable Reserve to reflect uncertainty in some of the modifying factors. Stockpiled material is included in the appropriate ore reserve estimate as Proved Reserve (with the exception of Mixed ore). Economic pit limits were determined using the Whittle 4X software package; Ore Reserves herein quoted are based on the 'Ultimate Pit 42NB', generated using Measured, Indicated and Inferred Resources for Sulphide and Oxide material types only. This practice allows the maximum size of the pit to be used in strategic mine planning activities and reasonably reflects the future mining potential of the deposit, subject to future infill drilling. Reported Proved and Probable Reserves are derived from Measured and Indicated Resources only within the Ultimate Pit, after modifying factors have been applied. The Ultimate Pit obtained by removal of Inferred Resources from the pit optimisation is smaller (Ultimate Pit 42SP), and as a result has a lower reserve base. Proved and Probable Reserves in this smaller pit, including stockpiled ore, are reduced to: Sulphide ore: 1417 Mt at 1.24 per cent TCu, LG Float ore: 453 Mt at 0.60 per cent TCu, Mixed ore: 45 Mt at 1.10 per cent TCu and 0.34 per cent SCu, and Oxide ore: 186 Mt at 0.72 per cent SCu. As there are differences in convention within the industry as to which reserves numbers to publicly report, both are provided to maintain transparency. The Inferred Resources located within the mine plan declared in the previous statement (June 2002), did not include 27 million tonnes at 1.21 per cent TCu, which has been corrected in this declaration. The downgrading of Measured Resource to Probable Reserve for Mixed ore was omitted from the previous statement and has been corrected in this declaration.
(5) An Ore Reserve has been declared at Escondida Norte for the first time in 2003. The Escondida Norte deposit is a supergene-enriched porphyry copper deposit of Oligocene age in which
two major stages of sulphide and one stage of oxide mineralisation contributed to the formation of a giant copper deposit. The principal copper-bearing minerals are chalcocite,
chalcopyrite and brochantite/antlerite. The copper mineralisation is a satellite ore body of the main Escondida mineralisation located 5km to the north. The western extension of Escondida
Norte is named the Zaldivar deposit, currently mined in an open pit by Cia. Minera Zaldivar Ltda. The final feasibility study of Escondida Norte was approved by BHP Billiton and its
partners in June 2003 as part of the Escondida strategy to maintain copper production capacity in future years. Development costs are estimated at US$400 million, which include pre
mine development, new mining equipment, a primary crusher with an overland conveyor, and maintenance and operating support facilities. Pre-mine activities are programmed to start in
September 2003 and copper production from the Escondida Norte deposit is scheduled for the fourth quarter of CY2005. The deposit will be mined using open pit, bulk-mining methods
with mineral processing through conventional flotation to produce a high-grade copper concentrate and oxide heap leaching to produce copper cathode. The mine design is based on
truck and shovel methods with direct haulage of waste and in-pit crushing of ore, for a total material movement of approximately 450,000 tonnes per day (tpd). Escondida Norte Sulphide
ore will be processed at an initial rate of approximately 85 000 tpd, increasing to 100 000 tpd after two years of copper production. Sulphide ore will feed both the existing Los Colorados
concentrator and the new Laguna Seca concentrator, blended with Escondida ore.
(6) Third party reserve audits have been undertaken on Cannington and Tintaya in the past three years.
(7) %TCu - per cent total copper, %SCu - per cent soluble copper.
(8) Tintaya Sulphide production was temporarily halted in November 2001 as a reaction to oversupply in the global copper market, and the oxide operation was commissioned during the
year. Tintaya Sulphide production is being restarted during the first half of FY2004.
(9) Test work done on M4 material mined early in the pit life and currently contained in the 4155W stockpile and 4174 Finger 'B' stockpile has indicated that this material is not economically
millable. Consequently, this material (approx. 1.7 Mt) has been excluded from the Reserve and Resource estimate. In early June of 2003, an area of Phase 2 and Phase 3 was identified
as containing a high percentage of total copper present as oxides and secondary sulphides. This type of material has previously demonstrated poor metallurgy. A preliminary interpretation
of the extent of this zone has outlined approximately 6 Mt of previously included Reserve material and 1.7 Mt of Resource material. Test work is ongoing on this material to determine its
true economic viability. Consequently, until such time as proven otherwise, this material has been excluded from the Antamina Reserve and Resource estimation numbers.

(1) The BHP Billiton Iron Ore Western Australia resources include those that support current mining operations and market grades, and also include resources to support future undefined
developments. All tonnages are in wet metric tonnes, except for Samarco, which is in dry metric tonnes.
(2) Resources are divided into joint ventures, and material types that reflect the various products produced. The bedded ore material types are classified by the host Archaean or Proterozoic
banded iron-formations. These are BKM - Brockman, MM - Marra Mamba and NIM - Nimingarra. The CID - Channel Iron Deposit or pisolite - are Cainozoic fluvial sediments.
(3) The resource grades listed refer to in situ, iron (Fe) and phosphorus (P).
(4) The total MM resources for the Newman JV have decreased by 67 Mt from the previous 2002 reported resource due to a revision in the Fe cut-off grade used to define the resource. Other
iron ore resource changes are predominantly related to production depletion.
(5) Whilst 85 per cent is shown as the 'BHP Billiton Interest' for Area C, POSCO (a Korean steelmaker) has a 20 per cent legal interest in the C deposit of Area C. In substance, the Group
retains virtually all of this interest and this disclosure and the financial statements are prepared on this basis.

(1) Competent Persons
(2) The total Mamatwan manganese resource has decreased by 27.1 Mt from the previous 2002 resource base due to additional exploration drilling and a re-estimate of the resource at a
higher Mn cut-off. Reduction in the Wessels and GEMCO total resources are primarily due to production depletion.
(3) GEMCO Mn grades are reported as washed sample grades and as such reflect a mineral product grade.

(8) The CQCA JV total Coal Resources has decreased by 12 per cent from the previous 2002 base due to depletion, remodelling, reclassification and a change in the minimum seam thickness for inclusion of underground resource from 1.5m to 2.0m. The Gregory JV total Coal Resource base has decreased by 36 per cent from the previous 2002 base due to the exclusion of structurally complex coal seam areas. The BHP Mitsui JV total Coal Resource base |
has decreased by 19 per cent due to changes as noted above for minimum underground mineable thickness. At Illawarra the Appin and West Cliff colliery boundaries were redefined and the mine plans revised to include the transfer of reserves from Tower mine which has closed and its Coal Resource transferred to Appin. Cordeaux mine has also been closed and part of its Coal Resources transferred to Dendrobium. |

(1) The Reserves listed for each joint venture include a combination of High Grade (direct crusher feed) and Low Grade (usually requiring beneficiation). All
tonnages are in wet metric tonnes, except for Samarco, which is in dry metric tonnes.
(2) The Reserve grades listed refer to head grades for iron (Fe) and phosphorus (P). Iron Ore is marketed as Lump (direct blast furnace feed) and Fines
(sinter plant feed). Samarco is marketed predominantly as direct reduction and blast furnace pellets.
(3) Mining dilution and mining recovery (in general around 95 per cent) has been taken into account in the estimation of reserves for all Western Australian
Iron Ore operations. For Samarco the mine recovery is 96.5 per cent (not included in the reserve estimate) of the stated diluted reserve.
(4) Metallurgical recovery is 100 per cent for all of the West Australian Iron Ores except for the low-grade part of the Mt Newman JV (350 million tonnes)
where the beneficiation plant recovery is 65 per cent. For both Mt Newman JV and Jimblebar the recovery of screened low-grade lump is 70 per cent and
55 per cent, respectively. For Samarco the beneficiation plant recovery is 57 to 59 per cent.
(5) The following third party audits have been undertaken: Mt Newman JV Long-Term Mine Plan Audit including the reserve base, MRDI, 1997; Jimblebar
Mine Planning Review, MineNet Consulting Mining Engineers, 2003; and Mt Goldsworthy JV Northern Areas, Long-Term Mine Plan Audit, MRDI, 1998
and Mine Planning Review, Mine Operations, MineNet Consulting Mining Engineers, 2001.
(6) Drill spacings used to classify Proved and Probable Reserves for the West Australian Iron Ore deposits are between 100m by 50m and 200m by 100m;
for Samarco the drill spacings used are 50m by 50m and 150m by 100m for Proved and Probable Reserves, respectively.
(7) Ore types are BKM - Brockman, MM - Marra Mamba, NIM - Nimingarra, and CID - Channel Iron Deposit.
(8) Competent Persons
Mt Newman, Jimblebar, Mt Goldsworthy JV Area C and Yandi: P Schultz (MAusIMM)
Mt Goldsworthy JV Northern Areas: R Richardson (MAusIMM)
Samarco: J Tizon (MAusIMM).
(9) The iron ore reserves for the Mt Newman JV, Whaleback pit have decreased by 163 Mt from the previous 2002 reserve due to mining depletion and a
review of drill hole spacing that resulted in the reclassification of some Indicated Resource to Inferred Resource. The Inferred Resource is not transferable
to reserve. The changes to the reserve base for Yandi JV and Samarco are primarily due to mining depletion.
(10) Whilst 85 per cent is shown as the 'BHP Billiton Interest' for Area C, POSCO (a Korean steelmaker) has a 20 per cent legal interest in the C deposit of
Area C. In substance, the Group retains virtually all of this interest and this disclosure and the financial statements are prepared on this basis.

(2) Coal Reserve (metric tonnes) is the sum of Proved and Probable Coal Reserve estimates, which include allowances for diluting materials and for losses that occur when the coal is mined and
are at the moisture content when mined. Marketable Reserve (metric tonnes) are the tonnages of coal available, at specified moisture and air-dried quality, for sale after beneficiation of the Coal Reserve. Note that where the coal is not beneficiated the Coal Reserve and Marketable Reserve are the same.(3) Coal wash plant recovery:

audit by Runge P/L in June 2001. No third party audits have been undertaken on the Illawarra reserves in the past three years.(5) Reserves are quoted on air-dried qualities, as this is the basis they are sold on the international market.
(6) A drill spacing of 1000m is used to classify Proved Reserves and 1000m to 2000m to classify Probable Reserves.
(7) Competent Person for Queensland Coal Reserves is B Cox (MAusIMM), and for Illawarra Coal Reserves is B Clark (MAusIMM).
(8) Cordeaux has been closed and its remaining Coal Resources are now deemed as a long-term Coal Resource for Dendrobium. Tower Colliery was closed at the end of CY2002 and the
remaining Coal Reserves allocated to Appin.
(9) The Queensland operating mines recoverable and marketable Coal Reserves have increased by 37 per cent and 29 per cent respectively compared to the previous 2002 base. These increases
are due to new price assumptions, pit redesigns and the replacement of South Blackwater reserves with reserves from the Kennedy area; the increases have been partially offset by depletion due to production mining. Illawarra operating mines recoverable and marketable Coal Reserves have decreased by 24 per cent and 17 per cent respectively compared to the previous 2002 base. These decreases are primarily due to the closure of the Cordeaux and Tower collieries and depletion from mine production.

(4) New Mexico Coal Resources have reduced by 25 Mt from the previous 2002 base due to mining depletion, revised coal thickness and reclassification. Middelburg mine increased its total Coal
Resource by 37 Mt from the previous 2002 base; the increases were the result of remodelling following a drilling program. Optimum decreased its resource by 27 Mt following redefinition of the seam limits and remodelling following a drilling program. Other changes in South African Coal Resources are primarily due to mining depletion. The Mt Arthur Coal total Coal Resources have increased by 518 Mt over the previous 2002 resource base; this is due to the inclusion of Coal Resources that are potentially extractable by underground methods. The Cerrejon Coal Company Resource has reduced due to reclassification 67 Mt and mining depletion 27 Mt from the previous 2002 resource base.(5) New Mexico and Togara South Coal Resources are quoted on an in situ moisture basis; all other Coal Resources are on an air-dried basis.

(1) Third party reserve audits have been undertaken on the following operations: Bayswater, 1997-2001 Mincon volume audits; Mount Arthur North, May 2000/2001, Dr D Balydan of Geological
Management Services Pty Ltd; and Cerrejon Zona Norte (section of the Cerrejon Coal Company), August 2002 and December 2001, Mr P Riley, Exploration Computer Services, Lakefield, Colorado. San Juan mine: 1) Audit of the underground resource and reserve conducted in June 2000 conducted by Skelly & Loy, Inc; and 2) Audit of the technical design, modelling and planning data for the proposed underground mine feasibility study conducted by Marston & Marston, Inc in September 2000. This review included a review of the San Juan and La Plata modelling and planning data.(2) Mining method: OC = open-cut, UG = underground.
(3) Coal type: Th = thermal coal, Anth = Anthracite.
(4) Recoverable Coal Reserve (tonnes) is the sum of Proven and Probable Coal Reserve estimates, which includes allowances for diluting materials and for losses that occur when the coal is
mined and are at the moisture content when mined. Marketable Coal Reserve (tonnes) is the tonnages of coal available, at specified moisture and air-dried quality, for sale after beneficiation of
(5) Coal moisture content is on an as received basis.
(6) Mining recovery for Navajo mine is 95 per cent; San Juan Surface mining is 95 per cent; and San Juan Underground mining is 55 per cent.
(7) Drill spacings of between 125m by 125m and up to 750m spacing are used for Energy (thermal) Coal Proven Reserves. A drill spacing of 500m to 1000m is used for Probable Reserves at New
Mexico; for the South African and Colombian sites the Probable Reserve category is not used.(8) The reserves of La Plata Mine (1mt) were depleted during the financial year 2002/03 and the assets are currently being reclaimed and the mine closed.
(9) The unassigned, undeveloped Coal Reserves are based on feasibility studies.
(10) No market exists currently for Leandra North, therefore no marketable tonnes available.
(11) Competent Persons: Navajo: D Rawson (MAusIMM); San Juan, La Plata:
R Vanvalkenburg (RPE NM); Optimum: G J Cronje (SACNASP); Middelburg:
J C van der Merwe (SACNASP); Douglas: J H Marais (SACNASP); Koornfontein:
C W Joubert (SACNASP); Khutala, ZAC: M A J Visser (SACNASP); Mt Arthur Coal:
P Grey (FAusIMM); Cerrejon Coal Company, Leandra North, Pegasus:
C D Van Niekerk (SACNASP); Klipfontein Klipspruit: J L Pienaar (SACNASP).
(12) The New Mexico Coal Reserves have been reduced by approximately 45Mt due to unresolved mining rights. Khutala recoverable and marketable Coal Reserves have been reduced by 96
Mt and 104 Mt respectively due to remodelling of the reserves, changes in the extraction factor and mining depletion. Other changes in the South African thermal Coal Reserves are primarily
due to production depletion. The Mt Arthur Coal Recoverable and Marketable Coal Reserve have increased by 51 Mt and 37 Mt respectively; this is the net effect of reclassification of some
open-cut reserves to probable underground reserves due to a more favourable profit margin and a reserve depletion due to production mining. Coal Reserves at Cerrejon Coal Company have
increased by the acquisition of Patilla Norte Coal Reserves from the Colombian government.

(1) Mining dilution and mining recovery are accounted for in the reserve estimates.
(2) Reserves for nickel are estimated on the basis of a 1.1 per cent nickel cut-off, chrome is based on a 38 per cent Cr203 in situ chromitite cut-off.
(3) Metallurgical recoveries for the operations are: Cerro Matoso 86 per cent nickel; Western Chrome 73 per cent chrome; and Eastern Chrome 76 per cent chrome.
(4) Reserve audits for Cerro Matoso in the last three years are: July 2000, audit undertaken MRDI (Mineral Resources Development Inc), San Mateo, California to investigate grade bias of the
CMSA laboratory, on behalf of CMSA. Third party auditing has been carried out on chrome in the last year.
(5) Equivalent drill spacing of 30m for Proved Reserve, and 60m for Probable Reserve has been used for Cerro Matoso reserve classification. For the chrome mines the known (published)
continuity of the chromitite layers in the Bushveld Complex allows wide-spaced drilling to delineate Proved Reserves with 300m square grid (no structural complexity).
(6) Competent Persons: R Argel (MAusIMM) for Cerro Matoso, and C D Beater (SACNASP) for Eastern Chrome and Western Chrome.
(7) The Western Chrome and Eastern Chrome Reserves have been updated and reported as Run of Mine (ROM) plant feed and not as saleable product as reported in previous years. This change
in reporting has increased tonnage by 4.3 Mt and 17.7 Mt for Western Chrome and Eastern Chrome, respectively; chrome grades have reduced in each case. Nickel and Chrome Reserves have been depleted by mine production.Directors' Declaration

Dated in Melbourne this 9th day of September 2003
Note - the page numbers shown above refer to the appropriate pages in the BHP Billiton Limited 2003 Combined Financial Statements
Independent Audit Report
To the members of BHP Billiton Limited:
Scope
The financial report and Directors' responsibility
The financial report comprises the Statement of Financial Position, Statement of Financial Performance, Statement of Cash Flows, accompanying notes to the financial statements, and the Directors' Declaration for the BHP Billiton Group, comprising both BHP Billiton Limited ('the Company') and BHP Billiton Plc (and the entities they each controlled during the year), for the year ended 30 June 2003.
The Directors of the Company are responsible for the preparation and true and fair presentation of the financial report in accordance with the Corporations Act 2001. This includes responsibility for the maintenance of adequate accounting records and internal controls that are designed to prevent and detect fraud and error, and for the accounting policies and accounting estimates inherent in the financial report.
Audit approach
Our audit work has been undertaken so that we might state to the Company's members those matters we are required to state to them in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company's members as a body, for our audit work, for this report, or for the opinion we have formed.
We conducted an independent audit in order to express an opinion to the members of the Company. Our audit was conducted in accordance with Australian Auditing Standards, in order to provide reasonable assurance as to whether the financial report is free of material misstatement. The nature of an audit is influenced by factors such as the use of professional judgement, selective testing, the inherent limitations of internal control, and the availability of persuasive rather than conclusive evidence. Therefore, an audit cannot guarantee that all material misstatements have been detected.
We performed procedures to assess whether in all material respects the financial report presents fairly, in accordance with the Corporations Act 2001, Accounting Standards in Australia and other mandatory professional reporting requirements in Australia, a view which is consistent with our understanding of the Company's and the Group's financial position, and of their performance as represented by the results of their operations and cash flows.
We formed our audit opinion on the basis of these procedures, which included:
While we considered the effectiveness of management's internal controls over financial reporting when determining the nature and extent of our procedures, our audit was not designed to provide assurance on internal controls.
Independence
In conducting our audit, we followed applicable independence requirements of Australian professional ethical pronouncements and
the Corporations Act 2001.Audit opinion
In our opinion, the financial report of BHP Billiton Limited is in accordance with:
(a) the Corporations Act 2001, including:
(i) giving a true and fair view of the Company's and BHP Billiton Group's financial position as at 30 June 2003 and of their performance for the financial year ended on that date; and
(ii) complying with Accounting Standards in Australia and the Corporations Regulations 2001; and(b) other mandatory professional reporting requirements in Australia.
