Sunfish, I assume that you had not seen CASA's latest draft of the Part 91 operational regs? The current reg is fine, what is missing is a sensible CAAP (or AC when or if the new regs come out).
OzRunways is taken care of nicely by a new draft CAAP on EFBs. In fact, for private ops the draft CAAP is enough because it clearly (well, almost clearly) explains existing laws.
