If you have significant erosion problems, it's essential to seek help from qualified professionals. Start by consulting with a civil or stormwater engineer who can give you tailored advice for your situation.

Consider engaging a professional bush restoration company to develop a vegetation management plan for your unique situation.  The Australian Association of Bush Regenerators has a directory of professionals with skills in creek and erosion management.

You, or your professional bush regenerator, should also refer to the Riparian Land Management PDF, 359.11 KB chapter of the Wollongong Development Control Plan.
