A GROUP of jet ski riders has horrified onshore onlookers by closing in on two whales playing in Coast waters.
A witness to Tuesday morning's incident, who did not want to give his name, said about 25 people had stopped on a walking track near Alexandria Bay in Noosa National Park to watch the animals breach and play close to shore.
He said four jet ski riders arrived about 9.30am, coming to within 100m of the animals.
Jet ski riders are by law required to remain at least 300m away from whales and dolphins.
Boats can come to as close as a 100m caution zone but only if they travel at six knots or less and create no wake.
The witness said the four riders appeared to be seeing how close they could get.
"I don't know whether (or not) they were trying to corral them out," the witness said.
He said one of the riders appeared to celebrate as the animals headed out to deeper water.
"He's gone the big 'yeah' and he has raised his arm."
The witness said people on the shore were horrified, trying to call authorities to report the encounter.
He said there was another jet ski as well as a few boats also watching on but they had all kept their distance.
"Once the whales disappeared the riders turned their attention to a pod of dolphins.
"They circled them until they also retreated further out to sea.
"It is a shame to see a lack of policing for these morons on jet skis."
