Dropbox and Gmail to share the files - not what we want. Among other things we'd like to have the files stay within Australian jurisdiction.
If the files were securely encrypted, does it matter that they stay in Australia?
IANAL, but my understanding is a definite "Yes" to this. National Privacy Principle 9 applies even to encrypted data, because there's no hard and fast definition of what "encryption" means. NPP #4 requires us to take "reasonable steps" to secure information, and encryption is certainly one of those steps, for what the IT profession generally considers reasonable. For example, if I simply password protected an MS Word 97 document, there's no way in this day and age I could defend that as being "reasonable" encryption.
