I use Auspost's Air international, Auspost Domestic, DHL Express and DHL Global mail to ship all my orders. (Which service carrier will depend on your location and order value).
Parcels shipped with GlobalMail have an airwaybill generated - the parcels are picked up from my address via a DHL express courier who carries the package to DHL's GlobalMail Sydney facility. Once the item is in Sydney the parcels are sorted by zone and air freighted to a distribution center near the destination. They must clear customs before being transferred to your local post office and delivered in your regular mail.
Parcels shipped with Auspost's Air International service go through my local post office. They transit through a Brisbane sorting centre before being air freighted direct to your country of origin. After clearing customs they are handled by the domestic mail service in the destination country.
Pricing for international orders does fluctuate pending the strength of the Aussie dollar. In the spirit of transparency my current equation for shipping is; $3 AUD per order for postage consumable (like packaging, labels and adhesives) + $3 - $8.20 per item (pending weight and country of destination).
I work really hard to keep shipping costs as low as possible while still maintaining quality and reliability of service. Most domestic orders with Auspost will take 3-5 working days. Most international orders will take 4-12 working days. Unfortunately not all destinations are trackable. If you have not received your order within 15 working days please let me know and I will either track your delivery or happily send a replacement.
I ship orders within 3 days of notification of your order payment clearing.
