agree with wal and shivan, its no so much the crown land access.
40 km north of Orange a nature reserve
I would first check with Mid Western Regional Council and or Cabonne Council
Then lot of the access is through private land so land owner/s would have to give you thums up
Assuming i'm looking at the same document release june 2011 on page 17
3.3.3 Recreation and public use
The main attraction is the river, and associated camping, swimming, gold fossicking and
fishing. Most camping occurs downstream of the ford on the western bank of the river,
where vehicle access and space are available.
