Document format and locale facts for Australia

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Australian GST tax-invoice particulars and ABN presentation, the general five-year GST record period, electronic-record controls, and the Peppol eInvoicing boundary are reviewed from ATO and ABR sources. This generator does not transmit through Peppol. Registration, recipient-created invoices, adjustments, special supplies and transaction-specific GST treatment remain separate scopes.

• Required when applicable: For an Australian GST tax invoice, show the supplier identity and ABN and the applicable invoice particulars. The ATO applies different information tiers at or below and above A$1,000, and the recipient identity is required for the higher-value tier.Evidence AU_ATO_GST · reviewed 2026-07-12 · review by 2027-01-12 · automation advisory only
• Required when applicable: Keep GST records for five years from when the record was prepared or obtained, or the transaction was completed, whichever is later; longer rules can apply in specified cases.Evidence AU_ATO_GST_RECORDS · reviewed 2026-07-20 · review by 2027-01-20 · automation advisory only
• Guidance: ATO eInvoicing uses the Peppol network and is different from emailing a PDF. This generator produces a human-readable document only; it does not create or transmit a Peppol eInvoice. Electronic records remain subject to the same preservation and accessibility requirements as paper records.Evidence AU_ATO_EINVOICING, AU_ATO_ELECTRONIC_RECORDS · reviewed 2026-07-20 · review by 2027-01-20 · automation advisory only
