If you’re not already registered, find out how to register a fishery, cropping water or aquaponic system for the first time.

New owners and operators

If you’re a new owner or operator and you’re part of the same organisation as the current owner or operator, they should use this service to relinquish their registration and provide your details.

If the current owner or operator cannot provide your details and you’re part of the same organisation as them, we’ll ask you to provide supporting evidence.

Evidence can include:

  • minutes from a fishing or angling club meeting that documents the new owner or operator
