You may not need approval for minor maintenance work in non-sensitive areas around creeks. However, it's essential that any work is done with care to protect the creek's ecology.
We recommend that you use a qualified bush regenerator for removing priority weeds. You can search online or check the Australian Association of Bush Regenerators website for a directory of professionals with skills in creek and erosion management.
You should also use an experienced arborist for any tree management work. These can be found by searching online.
