About the ivory -- you need a CITES document throughout your country
to Australia (this can take at least four weeks to get that from your
official foreign department):  http://www.cites.org/ 

And you also need an expert's report from a registered expert/appraiser
for the CITES document.  I make them to anywhere in the world related
to my business.

Second, you need to know the former owner before you, the manufacture
date, and the name and country of origin.  Declare if the ivory is
original (yes or no) or a replacement, and when did that happen!

If you write in your shipping document that it has ivory, then you
need that CITES document -- no doubts about that!

Hartrodt can guide you also through that process.  They send the
pre-made documents of the expert appraiser to their office in another
country, they do a checkup and, if necessary, see about changes that
must be made.

Then your expert can make his official document, and in the meantime
your CITES Document must have arrived.  That all together goes to your
shipping company and you have to wait!
