Wading in a river

Section 38 allows anglers to be within the bed of a river or stream. In many areas this allows anglers to wade through whole river reaches quite easily. In some cases the bed of a river may be freehold title however
access to these areas for anglers is irrespective of ownership of the river bed . Please note that section 38 does not apply to lakes. In addition to this, many sections of a waterway may be Crown land. In some cases this crown land extends well beyond the bed of a river. These areas of crown land are usually ill defined and often unrecognisable. To find these areas of crown land please contact the nearest NSW Local Crown lands office.
Fishing from the bank
While section 38 offers anglers the right of access for the purpose of fishing, argument often arises with the physical definition of the bed of river. Section 38 of the act clearly states that the bed is that any section which is covered and left bare with the increase of flows other than at times of flood. The definition of where this point is located on a river is often subject to scrutiny. Clearly it is the intent of the legislation to allow access for fishing in some manner other than at times of flood.
The Department considers the bed of the river to be that area which is below but within river channel flood level generally this is at the top of each bank and does not extend to areas when the river shifts beyond this point i.e. at times of flood.
This area includes most areas of beach or gravel bars or areas considered a waterway defined under the Crown Land Management Act 2016.
