For Australian visas, you do not need to submit original documents. If you apply online, your documents must be scanned and attached as electronic files. If you apply on paper, you must submit a certified copy. This requires you to make a copy of the document, send it to someone who can “certify” it on your behalf, and that person has to write, “This is, as far as I can see, a certified copy of the original.
” It means that. Notarize the document.It has to be an Australian citizen or a non-Australian who works in one of the “eligible professions”, like doctors, judges, clerks of court, bank officers, police officers, etc.
