A group of Australians detained by Israel while trying to deliver aid to Gaza are set to be released and deported in the next 24 hours.

The 11 Australians were among 400 people taking part in the Global Sumud Flotilla to Gaza before being intercepted by Israeli forces at gunpoint in international waters on Tuesday.

In a statement on Thursday night, the Australian Delegation for Global Sumud Flotilla said the Australians were being taken by bus to Ramon Airport in Israel, where they were expected to board flights bound for Istanbul, Turkey.

'No one is in harm's way ... the dealing with them was very sensitive,' Israeli ambassador to Australia Dr. Hillel Newman told reporters in Canberra on Thursday.

The detention of the flotilla group generated widespread outrage after a social media post by Israel's National Security Minister Ben-Gvir overnight showed him gloating over flotilla participants as they were forced to their knees by guards.

In the video, Mr Ben-Gvir, who remains a minister, walks through a crowd of detainees kneeling with their heads on the floor as he smiles and berates a man whose hands are zip-tied.

Israeli Prime Minister Benjamin Netanyahu and Foreign Minister Gideon Sa'ar condemned their colleague National Security Minister Itamar Ben-Gvir's humiliation of the activists as 'not in line with Israel's values'.

The news of the Australians' return is especially welcomed by Chris O'Connor who revealed on the ABC on Thursday night that his daughter Neve O'Connor, 26, claimed she was previously beaten by Israeli soldiers.

Ms O'Connor, from Melbourne, was part of a separate flotilla which was intercepted near the Greek island of Crete on April 29.

She claimed it was during that previous interception that she was viciously beaten by a member of the Israeli Defence Force.

'She said she was kneed in the face, she was punched in the ribs, she was dragged across the outdoor area,' Mr O'Connor told ABC's 7.30 on Thursday night.

'The psychological torture was being in a stress position for many hours. They were sprayed with water and were subject to hypothermic conditions overnight, because it was very cold in the containers.'

Ms O'Connor was hospitalised in Crete following the interception but decided to join the latest flotilla headed for Gaza on Tuesday. She has not spoken to relatives since boarding.

Dr Newman, also sat down with 7.30 host Sarah Ferguson on Thursday night.

He denied the Australians, or any other captees, had been subject to violence.

'Every time there's a flotilla, there are false narratives and false accusations against the security forces of Israel,' Newman said.

'The flotilla itself is a provocation totally unnecessary. He argued aid could get through by other legitimate means and the blockade on Gaza was backed by the UN and prevented the smuggling of weapons into the region.

'I know that you're also going to interview the father (Mr O'Connor),' Dr Newman said.

'I just want to say to the father, I sympathise with the daughter because she has been taken up, swept up by a movement that does not check the facts.'

Mr O'Connor flatly refused Newman's denial of violence inflicted by the IDF.

'If you see the photos, there were plenty of photos of people with bruises,' Mr O'Connor said. 

'There were plenty of photos of people who had fractured ribs, plenty of video testimony.

'So no, I absolutely reject that it's just a lie.'

Jacinta McEwen - whose son Surya McEwen has taken part in the aid effort - said the parents of the detained activists were overcome with relief about their release.

'But we are so angry that the reason our kids sailed in the first place is because of the failure of Foreign Minister Penny Wong and Prime Minister Anthony Albanese to show a spine as they watched children be murdered and starved to death,' she said.

'We demand the government step up and do their jobs so the next lot of kids don't have to sail again in six months' time.'

Mr McEwen has previously been detained by Israeli forces after taking part in other flotilla attempts.

Last time, he had his head slammed against a steel wall and a dislocated shoulder, a broken collarbone and broken ribs from being kicked in the chest, his mother said.

Palestinian-Australian Global Sumud Flotilla spokesperson Subhi Awad said Mr Ben-Gvir showed the world how Israel treated unarmed civilians aiming to deliver food.

'Imagine what they do to Palestinians every day off camera,' the statement said.

Adalah Lawyers - a legal team acting for Arab minority rights in Israel - have received complaints from the flotilla activists about the use of tasers and rubber bullets, sexual harassment and degradation.

Foreign Minister Penny Wong has called for the release of the Australians after condemning the video posted by Mr Ben-Gvir.

'The images we have seen posted by Israeli Minister Ben-Gvir - who Australia has sanctioned - are shocking and unacceptable,' Senator Wong said on X.

'We condemn his actions and the degrading actions of Israeli authorities towards those detained.'

Senator Wong directed the Department of Foreign Affairs to call in Dr Newman to reinforce her message.

He met departmental officials in Canberra on Thursday.

The Executive Council of Australian Jewry slammed Mr Ben-Gvir for his 'disgraceful' treatment of the activists.

'Nothing can excuse the appalling behaviour displayed by minister Ben-Gvir against a group of people who were being held in custody in Israel,' president Daniel Aghion said.
