Barzan,

Once you get the clearance you need to go to an AUSTRALIAN Embassy, not a qatari one.

Signatory Countries to the Hague Convention for international validitiy of documents require that they be validated by Apostille by the foreign ministry of the country of origin.

That basically means the Australian Foreign Affairs office, known as DFAT needs to check the document and the signatures and put a wax stamp and give you a certificate.

This costs AUS$20 per document at most DFAT offices and takes 1 working day (minimum).

If you are already here in Doha, there are various theories on how this can be done.

For instance some have told me that a British embassy can do the job (which I doubt). The safest way is to mail it back to Aus and get a friend or family member to get the apostille and send it back.
