I have sent the same question to CASA a few weeks ago but no answer so far. That's why I thought I would try here as I am sure I am not the only person with a Special pilots Licence and maybe someone else has already asked and knows the answer. It is also clear from other threads on PPRuNe that there are people on here who have a good understanding of what impact the new regs will have so can't hurt to ask.
If I get a response from CASA I will post it here. In the meantime, if anyone already knows the answer, I would appreciate it.
