Will Post International sending tracked and insured via the fastest possible route depending on location for set postage price.  Likely to be sent express via Australia Post as I have found them reliable in the past.  (Usually 6 weeks to America and about 3 to UK.  Italy usually takes 6 weeks as Customs have been slow there in the past.)  Handeling time for International postage 4 days as takes a bit longer to organise, Australia postaging should be 2.
