Following consultation and in consideration of the submissions received in response to the draft proposal, speed limits are changing in the Barker Inlet and North Arm of the Port Adelaide River.

From 29 April 2019, the 7 knot speed limit area will be extended to the Barker Inlet and North Arm of the Port Adelaide River to improve safety for all users and marine life, detailed in the map attached.

Vessels must not exceed 7 knots in:

  • the Barker Inlet from St Kilda southwards to the Angas Inlet, including all inlets and creeks but excluding vessels operating in the marked channel from Barker Inlet Beacon 13 to Barker Inlet Beacon 35;
  • the North Arm from the historic shipwreck “Dorothy H Sterling” eastwards to the Angas Inlet, including all inlets and creeks (North Arm Area 1); and
  • the North Arm which lies between the Grand Trunkway Bridge and the “Dorothy H Sterling”, and within 50 metres of the mangroves on the northern side of the waterway (North Arm Area 2)

Speed limits will be in place where high-speed boats may be a hazard to other water users or marine life. However please remember speed limits are the maximum speed allowed and may not suit current conditions. Every vessel should travel at a safe speed so the operator can take proper and effective action to avoid a collision and stop within a distance appropriate to the circumstances and conditions.

I welcome you to contact me if you have any questions or concerns and thank you once again for taking the time to provide your views on this issue.

Kind regards,
