If you have a vessel registration, and you've been sent a renewal notice, you can renew the rego on or before the expiry date, online. You're also able to update your contact details, if applicable.
Vessel registration is available as a digital licence. You can view, show, update, and renew your vessel's rego on the Service NSW mobile app. To find out more about digital licences, see Get started with digital licences.Renew online
