Speed limits are in place where high-speed boats may be a hazard to other water users. Various harbours, areas of the Port Adelaide River, metropolitan beaches and some country beaches and sections of the River Murray are subject to speed limits.
If you intend boating, waterskiing or using personal water craft in unfamiliar areas, make sure you find out about any speed restrictions by contacting the Department for Transport, Energy and Infrastructure.
Speed restrictions apply to all boats under the following conditions.
A four knot speed restriction applies:
A four knot speed restriction also applies to all personal water craft, often known by other names such as as jet-ski or wave runner, within 200 metres of the metropolitan shoreline. This includes restrictions between Outer Harbor southern breakwater, the southern end of Sellicks Beach and the backwaters of the River Murray - unless zoned otherwise.
Similar restrictions apply to beachfront areas in many popular swimming and tourist beaches. These areas are generally well signposted, but check with the local council about speed restrictions that may apply wherever you intend to operate a personal water craft.
A 10 knot speed restriction applies while a boat, not a personal water craft, is being operated by an unlicensed person - minimum age 12 years with a licensed person in charge. A personal water craft may only be operated by an unlicensed person as part of a small vessel hire and drive business that have been so licensed by the Department for Transport, Energy and Infrastructure.
Similar speed restrictions also apply to many local areas. These restrictions are often detailed on signs located along the shoreline or near boat ramps.
There are many areas along the South Australian coastline and inland waterways that have restrictions on the type of boating activities that can be carried out. Signs are in place to advise about restrictions. There are penalties if you do not observe the controls or speed restrictions provided on these signs.
