AskLIS: What are the differences between US librarianship and Australian librarianship?

AshtabulaGuy writes “I turn to the collective world-wide-LISNewsterz-Wisdom for some advice. What are the differences between US librarianship and Australian librarianship? That is a burning question. Although Australia utilizes AACR2r, what is different in practice there? If an American was to be on exchange for a year, what would they likely expect?

Any pointers as to starting points for seeking knowledge in this case?”
