Exclusive | Lefty love boat: Greta Thunberg’s freedom flotilla rocked by sexual misconduct allegations

They’re going to need a bigger boat!

Greta Thunberg’s freedom flotilla, which set sail from Barcelona Sunday for another anti-Israel voyage to Gaza, has been rocked by scandal after one of its woke leaders was accused of “sexual misconduct” with at least three volunteers.

“A senior leader within the flotilla — a member of the steering committee, the highest governing body of the organization — engaged in sexual relations with multiple activists while on the boat heading to Gaza. Not one person. Not two. Three different individuals,” claimed Palestinian group Heart of Falastin in a social media post earlier this week.

“To do it on the boat, while heading to a nation undergoing genocide, with volunteers who are under your authority . . . is a clear violation of ethics and power.”

One Brazilian group named the alleged horndog as activist Thiego Avila.

“On a ship carrying humanitarian aid, a Brazilian shows up with his d–k swinging and the only thing he manages to do is f–k and get arrested,” Anti Esquerda Club, a group that describes itself as criticizing the left from the left, wrote on X Tuesday, pointing the finger at Avila — and referring to the Israeli Navy intercepting the flotilla and taking activists into custody.

Avila, 39, sailed to Gaza in June aboard the 12-person Madleen, where he was pictured in many chummy poses with fellow activist Thunberg — arms around each other’s shoulders and looking gleefully at one another — before they were eventually detained by Israeli forces and deported.

He joined the larger 500-activist Global Sumud Flotilla convoy in September, during which infighting among senior leadership led Thunberg to step down from the steering committee and off the main boat. The activist was then seen dragging her suitcase along a Tunisian dock to transfer to a different ship.

That tumultuous trip also saw her vessel’s radio hacked to pump songs from the Swedish pop group ABBA on full blast in a clear troll at Thunberg.

At the time, Thunberg’s decision to step down stemmed from frustration that leadership was spending too much time bickering about “internal affairs” and was not focusing enough on Gaza, according to Italian newspaper Il Manifesto, which had a correspondent on board.

Thunberg did not respond to questions from The Post about the alleged sexual misconduct, and whether it played a role in her own departure.

Avila, who left his wife and two-year-old daughter at home in Brazil to embark on what is now his fourth sailing trip since June — having gone twice to Gaza and once to Cuba — denied the accusations.

“These allegations are obviously not true,” he told The Post on WhatsApp Thursday while sailing off the coast of Spain.

“The ethics committee talked to all three people mentioned and they confirmed that this is just a smear campaign, that we are comrades and nothing ever happened,” he added, before embarking on a bizarre rant about the Epstein files.

The allegations have added fuel to critics’ fire that the flotilla is nothing more than performative activism, with socialists in it for a good time.

“At a time when Palestinians in Gaza are being starved . . . we would expect mobilization to reflect the respect and seriousness this moment deserves,” slammed the group Palestinian Reveals.

“Instead, we are seeing concerts, a large stage, music and celebratory atmosphere,” it added, referring to the flotilla kickoff party last weekend in Barcelona.

The flotilla aims to raise $3.5 million for the current trip, but its donor list is not public, and critics have said little to none of the money actually makes it to Gaza.

“As one resident living in the tents in Gaza said: ‘It would have been better to donate money to Gaza instead of throwing it into the sea without benefit,’” wrote Palestinian journalist Mohammed AbuSalama.

A spokesperson for the flotilla said an investigation into the sexual misconduct allegations against Avila, which first came to light in November, found no evidence of wrongdoing.

“In the absence of any complainant, witnesses or evidence, there was no basis for the matter to proceed,” the Global Sumud Flotilla press team told The Post.

But the organization hinted this wasn’t the only misconduct allegation it dealt with, even revealing it hired an “ethics committee” made up of trained legal professionals after the 2025 trips to keep everyone in check.

“The ethics committee has conducted investigations of this nature unrelated to the current allegations, and disciplinary action has been taken where evidence has warranted it,” it added.

Avila meanwhile didn’t do much to dispel the image about the flotilla’s party-loving socialists in his Instagram stories this week.

“We’re here with 38 boats. Look over there!” he gloated to his 1.3 million followers on video, laughing. “Yesterday we saw dolphins, now there’s a whale right here, look! That’s beautiful,” he exclaimed, before sharing a snap of the sunset along with Bob Marley’s Redemption Song.
