This will get you to the Australian doc.
Theoretically your conclusion is a no-brainer - but the practicalities can throw up some problems. Just as a quick example, the distinction between an active runway and a runway in use can very easily become blurred and it is vital that everyone knows the status of each runway at all times. On a nice calm day, with multiple runways available, a request from a pilot for a convenient runway which can easily be accommodated by ATC brings its own HF challenges.....I've read a report where this sort of thing feature (but I can't recall much detail more offhand, I'm afraid).
Probably the most important thing in all of this is to use standard procedures/RTF and adherence to those procedures. Many runway incursions occur simply because the procedures in place were not followed (or maybe they weren't very good) and misunderstandings arose.
