The Consul-General in Papeete does not provide notarial services (e.g. witnessing signatures, certifying true copies or originals etc). Consider checking with your relevant Australian authority whether there are local options such as a foreign citizen who holds a particular title or occupation (e.g. notary public, lawyer, police officer, etc) who may be accepted as a witness to your documents.
A directory of notaries public in French Polynesia can be found on the website of the Chamber of Notaries.
