DO NOT approach

If out on the water please slow down, keep a lookout and do not approach dolphins.


Do not approach within:

  • 50m of a dolphin

  • 150m of a calf or a dolphin that is sick or injured

It is fine if the dolphins approach you but please do not approach them. It is important that dolphins are able to feed, rest and play.

Please observe the speed limits.

DO NOT feed the dolphins

Feeding wild dolphins is illegal and very harmful for them. Dolphins have many different fishing techniques and are great at catching their own fish.


Feeding dolphins alters their behaviour and causes them to hang around boats and areas where people are fishing increasing the likelihood of them being hit by boats, becoming caught in fishing line or deliberately harmed.

Dolphins are protected marine mammals. It is illegal to feed, harass or harm dolphins. Fines apply.

There are currently 3 new calves in the ADS

Please slow down. Do not approach within 150m of a mother and her calf.

It's calving season. There are currently new calves in the area. Please slow down on the water and look out for calves.

Calves are very vulnerable in the first few months of their life. It's important they have the opportunity to rest, feed and improve their swimming skills.

Boats, kayaks and other watercraft are not to approach within 150m of a mother and calf, and not within 50m of other dolphins. Jet skis should not approach within 300m.

Dolphins are protected marine mammals. It is illegal to feed, harass or harm dolphins. Fines apply.

There are many simple ways you can help protect the Dolphins and their habitat

Marine Mammal Strandings

Fishing line



FEB-APR 2023

CAUTION: Mother and baby dolphins in the area

Please reel in fishing lines when dolphins are close

Unfortunately we have had dolphins that have suffered serious injuries and even died due to fishing line entanglements. Please reel in lines if dolphins are nearby and please make sure to dispose of fishing line and rubbish in the bin.

Please do not throw fish scraps in the water. This leads to dolphins scavenging and hanging around people that are fishing increasing the risk of entanglement.

Try and avoid using plastic bags and dispose of rubbish responsibly

Plastic bags take years to break down and sadly often end up in our waterways.

Ensure the drain is just for rain

Storm water (from our streets) goes straight to the sea. Prevent rubbish and chemicals from washing into the drains.
