Summer holidaymakers have been warned to keep their distance from dolphins after reports of jet skiers harassing the creatures along Victoria's Mornington Peninsula coastline.
There have been several reports of jet skiers driving too close to dolphins at Tyrone Foreshore Beach near Rye, prompting a crackdown from the Conservation Regulator on Friday.
It is urging the public to report any information on the incidents or other cases of wildlife harassment to Crime Stoppers and warned those responsible could face a fine of up to $3698.
In Victoria, people must stay at least 100 metres away from dolphins when on a boat or 300m when jet-skiing.
Boat drivers and jet-skiers should slow down or stop altogether if a dolphin or dolphins approach, the Conservation Regulator advised.
Beachgoers should also steer well clear of sun-tanning seals resting on the sand, and look out for hooded plovers so as to not scare the vulnerable birds away or trample on their nests.
Acting Chief Conservation Regulator Callie Donaldson said harassing dolphins and other wildlife is cruel and unacceptable.
"Small changes to your behaviour can make a big difference to wildlife welfare," she said.
"Our patrols are focusing on engaging with the public to make sure they know the rules, and anyone caught doing the wrong thing is held accountable.
"We're lucky to have iconic wildlife species living along the coast and we want beachgoers to safely share the beach with them."
