G'Day mate, hope you're enjoying life up there.
As you say, what it is is not in question, so to answer the technical side of the question (the difference), I've had a look through PANSOPS and can't find the term. I have, however, found the following reference for the South African CAA that might have some search terms that you could search for in ICAO type docs
Cloud break procedures may be approved by the
Commissioner for Civil Aviation, when one or more
of the following conditions apply:
Such procedure is conducted outside con-
trolled airspace.
Such procedure is conducted inside con-
trolled airspace.
The runway and/or equipment does not
comply with the ICAO requirements.
The final approach track is not aligned with
the runway.
Local QNH may not be available.
Have you tried e-mailing Ozexpat?
