Not sure whether you require a notary public to witness or verify your documents? –
IF YOU ARE SENDING DOCUMENTS OVERSEAS THEN YOU PROBABLY NEED TO ENGAGE A NOTARY PUBLIC
You can upload a copy of your documents during the online appointment process for that advice and also obtain a quote for the necessary services.  Alternatively, email your query regarding the notarial services you require.  The Notary can provide you with advice at the time of your appointment whether you will need an Apostille or an Authentication which are issued by the Department of Foreign Affairs and Trade (DFAT) but you need to ascertain the requirements of the country in which the documents are going to be used.

A special note about Australian University degrees – the Notary will provide a certified copy of your degree and attach a separate Notarial Certificate verifying that  the degree was issued to you.  This can be done by the Notary confirming the issue via the online certification portal of the relevant university or by direct enquiries with that University if necessary.  Otherwise your degree or award must be verified and signed as a ‘true and accurate record’ by the central student administration office of the issuing institution before attending the Notary.
