The VH bit, as I read it, only applies to integrated PPL / CPL aeroplane courses. Compare 61.590 and 61.610, the integrated CPL aeroplane class requires the flight time to be completed in a registered or recognised aeroplane (61.590(4)), whereas the non integrated does not have this requirement. (See 61.525+61.545 for PPL aeroplane)
With reference to the RAAus membership requirement, pilots are exempt of certain regulations by the various CAOs (95.10, 95.32, 95.55). The CAOs also state these exemptions are subject to compliance with RAAus Operations and Technical manuals, if those manuals require you to be financial members that's what you need to do. These manuals provide an alternative means of complying with the exempt regulations.
