Please always take care while driving your boat near dolphins or other marine mammals. Several of the Mandurah dolphins have severely disfigured dorsal fins some of which may have been damaged by boat propellers
The photos below kindly provided by Jennifer Semro of Dolphin Defenders and our friends at Project Pod in the USA clearly show the horrific damage that can be caused by boat propellers and why care is always needed

Never crowd or harass dolphins particularly if dolphins are mating or have young. If dolphins wish to leave an area do not continually pursue them, let them leave. Leave dolphins completely alone if they begin to show signs of annoyance or aggression which in dolphins include tail slapping on the water, open mouth gestures, jaw claps and possibly loud exhaling.
Note: The famous dolphins at Monkey Mia are fed only small amounts of fresh fish under VERY strict conditions and under CONSTANT ranger supervision to ensure the health of the dolphins is not affected. Even so, there are many people who believe the feeding should cease, and believe the feeding increases the wild dolphins dependence on humans. Only a small number of dolphins there come into shore to receive these irregular handouts, most of the dolphins at Shark Bay do not come into the shallows and have never accepted food from humans.
It is both careless and harmful to attempt to feed other wild dolphins and may also be illegal.
Attempting to feed wild dolphins endangers the dolphins health. It poses a serious health risk or even death from possibly non natural food or bacterial contaminated fish that is not 100% fresh. Also dolphins always eat their fish head first, so if fed by humans they could choke on bones or fillets or unaccustomed food. Dolphins can also become dependent on handouts, leading them to change from their natural behaviour of hunter to scavenger. They then may start to scavenge from fishing lines or nets, leading them to ingest fish hooks or be caught in netting, and a painful death. You could be unintentionally responsible for the dolphins suffering or death and also fined under the Mammal Protection Act. In short, DONT.
Dolphins around the world are seriously health effected or die from industrial effluent including heavy metals, poly chlorinated biphenyls (PCB's) and by bacterial and viral pollution from sewerage outfall. They may also die from entanglement in fishing nets or by ingesting plastics such as plastic bags, and refuse including cigarette butts. Or their snouts may become entangled in plastic beer rings leaving them to slowly starve to death by being unable to feed. Thousands of kilometres of nets and line, and hundreds of thousands of tonnes of plastics are dumped into the world's oceans each year.
If you see any plastic products or rubbish in the water please retrieve them and make sure your rubbish is always placed in a rubbish bin.
