as a private individual on a one off basis? NO

here's an extract from a post made here last year by one of the Australia Post representatives

''To set the record straight, perfume is considered a "Dangerous Good" (see http://auspo.st/gkrogS) and therefore will not be accepted for carriage through domestic or international post. If you have been advised otherwise by staff at your local Post Office, please let me know their details and I will ensure they are re-trained with the correct information.

If you have sent perfume in the mail you will not be covered for loss or damage regardless of the service it was sent through as it is a prohibited item as advertised in the Dangerous Goods Guide (linked above).

As others have mentioned it is possible to send perfume and other dangerous goods provided you have a Dangerous Goods Licence with us [Aust Post], which requires you to undergo special training as well as complete specific paperwork for each parcel. "

If you would like to discuss the specific costs and requirements of obtaining a Dangerous Goods License, contact Australia Post directly.
