Kingsdale Master Cave, Kingsdale (West)
Rigging
Master Cave can be rigged either in the centre or on the left. A 15m rope will suffice for either, but might not allow for doubling the first anchor on the traverse if rigging on the left.
The rescue traverse requires a long rope. Unsure on the precise length, but 35m seemed to get me about half way.
East Entrance Passage / Simpson/Swinsto Final Chamber
Warning: Connecting boulder slope reported to be unstable.
Rowten Sumps
Wetsuit/neofleece is important. In order from this end, they are 2m, 4m, 8m. The 2m sump often has a small airspace in low water.
Make sure you’re in the right place as there are lots of other sumps in the area which aren’t free-diveable.
Free-dive line is anchored in the ceiling, so air bells are obvious. Both air bells are large enough to fit two people at a time.
Final (8m) sump can silt up and collect farming wire etc. - be aware of this risk.
