Hi Peter, welcome to the VSA forums.
If you seek cave locations here you will need to introduce yourself and any caving organisations you are associated with. A mutual trust must be developed and then information may be revealed privately.
I can safely say that the old road is closed and a new one has been opened up. Its still possible to drive as close to the cave as previously, but some sections of the track are very rough and steep. As the sign says at the main gate, "4WD access only".
