OK, CAO 95.55, para 7.3 makes no reference to the original question asked and refers solely to controlled i.e. alphabet airspace. AIP ENR 5.3 (if that is the correct reference) talks about the issuing of notams for restricted and other areas. The CASA Project document is not legislation. Nothing to do with recreational flying in my case, I have decades of professional aviation experience and I can't find it.
