All I see in #70 is that you have the right to challenge your revocation of your flying permission by SAFA by writing to CASA, if CASA denies, you can then take CASA to AAT for that decision. If however you have flown before any decision is formalised, being aware that you were grounded, you have acted illegally as you are not authorised to fly. Same as if your drivers licence is revoked, you can't drive around while the matter is resolved, unless you are given express permission to do so.
