Checkboard I think you will find that applying your "25,30 VIRD" mnemonic would preclude a departure from the majority of airports in Australia as they do not have published SIDs.
It precludes an
IFR departure in which you commit the aircraft to flight in cloud below the LSALT/MSA, yes, as you have no procedural terrain separation. If you can get (visually) to circling altitude, then you can follow the missed approach from the circle, in the same way that you would for losing vis while circling, but if there isn't a published Instrument Approach then you're committed to VFR until above the MSA/LSALT.
Provided one can orbit within 3nm of the departure airport you can then climb to MSA/LSA before setting course.
Where does it say that?
