G'day Rob,
Don't know if this will help but it shows how the cunjie is baited on your line.
Pic was scanned from a "Fishing World Magazine" October 2008 issue page 43.
The rig is size 2/0 hook with a small ball sinker running straight on top. Use a strong hook....Rod to use is about 10-12 foot...20-301b mainline.
Hope this helps you somewhat.
Peter
