I fly through there quite a lot, when active and when not.
It's one thing to plan through it on an IFR plan, quite another to need clearance any time you want to do a few circuits. Plus all RA-Aus pilots are not welcome as active restricted areas are to be treated as class C...
Not knowing the location, I can't tell, but of it is at the edge and doesn't infringe IFR approach paths, then I imagine they might be open to doing the same as we have here at Gawler, I nice cut-out with enough altitude to get out VFR without clearance.
