Only been there once, a couple of years ago. Got in the morning before the RAAF was flying and left before they started again a few days later.
Looked amazingly difficult to follow the lanes in and out if they were active as I didn't see the visual checkpoints the chart talks about.
Might not be too much trouble to transit overhead with a plan in the system.
To check that your plan actually IS in the system (VFR) do a SARTIME amendment after you get airborne. You may be surprised.
I've put in VFR plans out of Camden and had them disavow all knowledge when checking in for a clearance through Richmond zone. Going over the mountains wasn't an option thsecond time due weather so they rummaged around on the floor and finally found it. There's a VFR reporting point just to the north outside the Class D at Camden, the controller wanted to know where that was when I checked in. Impressive, professional, friendly - NOT.
In 20 years I can recall two occasions in Australia where the controller was the above.
