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.
Provided one can orbit within 3nm of the departure airport you can then climb to MSA/LSA before setting course. If you were departing YPOK which has high terrain within the 3nm then it is obviously not a wise choice to depart into cloud which is obscuring the obstacle.
There are many grey areas in the regs which require a PIC to assess the situation purely from the current conditions ie. cloud base and known terrain in the area. The 3nm is considered circuit area and under NVMC procedures when inbound one must maintain the last LSA until within the 3nm before breaking off and going the circuit.
