Key facts

Concise statements from the verified fields on this page. Missing values stay unavailable — we do not invent statistics.

Australia's ISO 3166-1 codes are alpha-2 AU, alpha-3 AUS, and numeric 036. ISO alpha-2 and alpha-3 are different country-code formats.
Australia's international telephone calling code is +61.
Australia's currency in this dataset is Australian dollar (ISO 4217 AUD, symbol $). A currency symbol does not always uniquely identify a currency — prefer the ISO 4217 code.
The capital listed for Australia is Canberra.
Australia may use more than one time zone (11 IANA identifiers listed on this page). There is no single national clock for every location.
Australia's postal-code format in this dataset is “####”. Postal-code format validation does not confirm that an address exists.
Driving side listed: left.
Measurement system listed: metric.

At a glance

Country-specific notes grounded in the verified fields below.

Several Australian zones (e.g. Australia/Sydney, Australia/Adelaide, Australia/Perth) with different DST behaviour.
Left-hand driving; metric units.
Postcodes are four digits — state/territory context matters for delivery, which this tool does not verify.

Codes & dialing

ISO 3166-1 alpha-2 ISO 3166-1: AU Two-letter country code as used in this catalog.
ISO 3166-1 alpha-3 ISO 3166-1: AUS
ISO 3166-1 numeric ISO 3166-1: 036 Three-digit UN M49-style numeric code from the dataset.
International calling code Calling +N: +61 Country calling code +61.
Internet TLD: .au

A country calling code (telephone dialing prefix) is not the same as an ISO country code. Codes above are third-party reference values — not an official ISO product listing.

Currency & languages

Currency ISO 4217: Australian dollar (ISO 4217 AUD) · symbol $ · minor units: 2 Tender from the open-dataset snapshot — third-party reference, not live exchange rates. Prefer the ISO 4217 code when a symbol is shared.
Languages (dataset identifiers) ISO 639: English eng Identifiers as recorded in the assembled datasets — not a complete official language schedule.

Time zones

Live local time from IANA identifiers (server/OS tzdata). Offsets can change with daylight saving.

Practical details

Postal code format Format only: #### Four-digit pattern (####). Format only.
Driving side Third-party: Left
Measurement system Reference: Metric Imperial listed for US, Liberia, and Myanmar in this snapshot; otherwise metric as the prevailing customary system in reference sources — not a legal metrology certificate.
Area km²: 7,686,850 km² Reference snapshot area in square kilometres when present.
Population Estimate: 27,400,013 Third-party reference estimate · effective year 2024 (not a live census)
Nationality (demonym): Australian
Independent: Yes As recorded in the open dataset — not a legal status determination.
UN member: Yes As recorded in the open dataset — confirm with the United Nations for official membership lists.

Locale & conventions

Common practice for orientation — not a substitute for local legal or institutional rules.

Dates commonly DD/MM/YYYY.
Currency: Australian dollar ($ / AUD) — disambiguate from other dollar currencies.
International dialing: +61; drop the leading 0 of the national number.

Trust & provenance

Data class: Third-party open reference data assembled for tools — not an official ISO, UN, or national-statistics publication.

Profile editorial date: 2026-10-23 (publication set for curated copy)
Source evaluation reviewed: 2026-10-22 (UTC calendar date)
Reference dataset snapshot: 2026-10-22 21:03:56
Effective dataset note: Imported static snapshot used by CountryCatalog / ref_* tables; population year typically 2024 from upstream snapshot metadata.
Live clocks: IANA via PHP at request time (depends on server/OS tzdata). Not a stored permanent national offset.

Standards & definitions in use

ISO 3166-1: Country codes: alpha-2, alpha-3, and numeric identifiers as used in our catalog (not a sold ISO product dump).
ISO 4217: Currency codes (and symbols when present). Symbols may be shared across currencies.
ISO 639 (dataset identifiers): Language codes as recorded in the assembled open datasets — not a complete legal language schedule.
International calling codes: Country/territory telephone dialing prefixes (E.164-style +N). Distinct from ISO country codes.
IANA Time Zone Database: Zone identifiers and live offsets via PHP/OS tzdata at request time. Offsets can change with daylight saving.
Area (km²): Land/area figure from the reference snapshot, expressed in square kilometres when present.
Population (estimate): Reference estimate with an effective year when known — not a live census API.

How empty values are labeled

Not available — missing from the verified dataset (not invented).
0 — a recorded zero when the source supplies zero (distinct from missing).
Does not apply — used only when a field is explicitly not applicable (rare).

Data limitations

Not an official ISO, UN, or national-statistics publication.
Population and area are reference estimates with effective year where known.
Postal checker validates format only — not delivery-point existence.
Currency finder does not show live FX rates (see Currency Converter for rates).
Driving side / measurement may be incomplete for some territories.
Administrative divisions are not bulk-published (avoids thin/incomplete geography pages).
Timezone “now” depends on server/OS tzdata freshness.
ODbL sources require attribution and share-alike considerations for redistributed database dumps.

Frequently asked questions

Does all of Australia observe daylight saving?

No. Some states and territories do not. Check the specific IANA zone on the Australia time-zones page.

What is Australia’s currency code?

AUD — Australian dollar.

What is the difference between a country calling code and an ISO country code?

A calling code is an international telephone dialing prefix (for example +92). An ISO 3166-1 country code identifies the country in data systems (for example PK, PAK, or 586). They serve different purposes and are not interchangeable.

Does a country always have one time zone?

No. Some countries use a single IANA zone; others span many. This profile lists the zones available in our catalog — use the country time-zones page for live clocks.

Does a valid postal-code format prove that an address exists?

No. Format checks only compare structure to a documented pattern. They do not confirm delivery points or that a code is currently assigned.

Where does this country data come from?

Fields are assembled from maintained open datasets (ISO codes, calling codes, currencies, languages, postal patterns, population/area) plus live IANA time zones via PHP. Editorial notes are written for this profile. Unavailable fields are labeled — we do not invent values.

Are population and area official census figures?

They are reference estimates from the dataset snapshot (year shown when available). For legal or statistical work, confirm with a national statistics office.
