Just thought it may be of interest here that the first crossing of Judd's Creek (on Judd's Creek Rd) has been washed away in last Friday's flood.
This is the access to the Billy Brown's Falls walk.
The damage is quite substantial, and the section is not crossable - even with a 4WD.
I guess if you really wanted to, you could park here, wade across the river (pretty fast flow today) and walk to the track head, but that would add about a 6km round trip on dirt roads. Plus, the second crossing may be out too.
