HSC in NSW was the Board of Studies and is now NESA. There are two ways to get an apostille on an HSC document. The first way is to get a copy of the original document notarised by a public notary. The second way is to get the department to stamp a copy of the certificate.

Getting a stamp from the Department will take 7-10 business days and involves filling out a very long form and getting signatures from the person who was granted the certificate. The service also costs $46.70 per document.

A notary will charge $120-$200 for making a copy of the original document but the notary will need to sight the original document. The notary will get the document notarised on the spot so that you can get an apostille.
