Every visa application requires various supporting documents such as birth certificates, marriage certificates, proof of identity etc.
Unless asked to do otherwise, you should provide 'certified copies' of original documents, rather than the original documents.
'Certified copies' have been authorised (or stamped) as being true copies of originals, by a person or agency recognised by the law of the country in which you live. All departmental offices outside Australia have a person who can certify or witness documents. You may have to pay for this service.
Police certificates are the exception. You must provide original police certificates with your application.
