Within Australia, the Department of Foreign Affairs and Trade Provides a small number of notarial services through the Australian Passport Office. These include:
• Issuing of Certificate of no Impediment to Marriage (CNI).
• Issuing Apostille and/or Authentication certificates. These certificates legalise the signatures and/or seals on Australian public documents.
• We can certify copies of Australian Travel Documents
• We can witness signature on the application form for certificate of no impediment to marriage (CNI).

What we cannot do:
• We cannot certify copies of documents or witness signatures. If you require these services then you should contact another provider. For example, a Justice of the Peace or an Australian notary public.
• We cannot legalise foreign documents or documents issued by non-government organisations.
