You can choose to send your entire order using Australia Post Parcel Post (not exactly rapid) for $8 or Australia Post Express Post (faster) for $12.
Orders over $200 receive free postage. Australia Post tracking details are sent via email once the order has been processed. Tracking details can take a day or two to appear online.
Signature on delivery is not used as it rarely enforced. If you're concerned about your mail being stolen, use a Parcel Collect address, Parcel Locker or a PO Box.
Rest of the world.
Please send an email to email@example.com containing what you'd like to order, along with your name, postal address and contact telephone number. I'll reply with a quote excluding Australian GST and including postage speed options and prices. Payment will be via PayPal or international bank transfer.
International postage from Australia is ridiculously expensive, so I don't send books to addresses outside Australia. Instead, please order them directly from No Starch Press or Amazon.
