There are mistakes in the CASA Jandakot Visual Pilot Guide too. When I asked CASA about this, eg the taxi call for VFR including "request clearance" which had controllers snarling I was told with a shrug "It's not a controlled document". The reference is the AIP, not the CASA guide.
Similarly, the reference for instructors is the MOS, not the Flight Instructor Manual. I have encountered newly trained instructors and students coming up for test who have never seen or heard of the MOS.
