In New South Wales (NSW), a wide range of professionals and officials can certify documents as true copies of the originals. These authorised certifiers include:

• Justice of the Peace (with a valid registration number in NSW)
• Police officers
• Judges of a court
• Sheriffs' officers
• Barristers, solicitors, and patent attorneys
• Medical practitioners
• Bank, building society, or credit union officers with at least five years of service
• Postal managers
• Principals of Australian secondary colleges, high schools or primary schools
• Commissioners for declarations
• Ministers of religion authorised to celebrate marriages
• Accountants who are members of recognised professional bodies or registered tax agents

Certification must be done in person by an independent third party who checks the original documents and copies to certify that the copies are true and accurate. The certifier must sign, date, and provide their full name, profession, registration number (if applicable), and contact details on the certified copies with a statement such as "I certify this to be a true copy of the document shown and reported to me as the original" on each page.
