The translation type depends on the recipient, not the document. Australia's Department of Home Affairs requires translations made in Australia to be by a NAATI-certified translator, while translations made outside Australia must show the translator's name, address and qualifications. Some European countries require a sworn translator appointed by their courts. Thai authorities and many countries accept a translator-signed translation with certification by a Notarial Services Attorney or legalisation at Consular Affairs. Get the recipient's requirements in writing before translating.

About NAATI
Per the Home Affairs guidance page, translations made in Australia must be by a NAATI-certified translator; translations made outside Australia must include the translator's details. Read that page for your actual visa, as requirements can change.
