You need to register a vessel to use on NSW waterways if it:
<ul> <li>has an engine of 4kW or more</li> <li>is 5.5m or longer (with or without an engine)</li> <li>is a personal watercraft (PWC)</li> <li>needs a mooring licence or marina berth.</li>
There are penalties for operating an unregistered vessel.
If you have interstate or overseas registration, and you’re moving to NSW, or using NSW waterways longer than 3 consecutive months, you need to register the vessel in NSW. You can do this by following the steps on this page. If unsure whether you need NSW registration, see interstate or overseas registration.
Domestic commercial vessels (certain vessels used for a commercial, governmental or research activity) do not need NSW registration when operating under the Marine Safety (Domestic Commercial Vessel) National Law Act 2012. See Australian Maritime Safety Authority (AMSA).
