Concerns are growing for Newcastle activist Zack Schofield after Israeli forces recently intercepted all vessels in the Global Sumud Flotilla.
It’s resulted in the detention of hundreds of humanitarian volunteers, including 11 Australians.
Mr Schofield has not been heard from since 5.30pm AEST on Monday 18 May, when communications were lost as the flotilla was first intercepted in international waters.
His welfare and exact whereabouts remain unknown, with families and the Department of Foreign Affairs and Trade all confirming they have had no contact since the incident.
The Israeli Foreign Ministry said 430 volunteers were transferred to Israeli vessels and taken to Israel.
Close friend Alexa Stuart said Mr Schofield’s final message came shortly before contact was lost, warning of a possible interception.
“Possible interception now, I love you all,” he wrote in the group chat, she said.
Alexa said the message was distressing to receive but reflected his conviction and commitment to humanitarian work.
“I think it was scary receiving it,” she told the Newcastle Weekly.
“But, I feel comforted knowing Zack’s strength and moral conviction.”
She described him as “a very morally principled, dedicated and selfless person” who was motivated by the suffering of civilians in Gaza.
Alexa added there had been reports the detained volunteers were being taken to Ashdod and may later be transferred to a prison facility in Israel.
However, there’s no confirmation of their condition or location.
She also said there were concerns Mr Schofield, who’s been detained twice in the past month, may be among those participating in a hunger strike, as he indicated he intended to do so if he was detained again by Israel.
“The land support team of the Global Sumud Flotilla hasn’t made any sighting of the 430 hostages,” she explained.

Mr Schofield’s parents, Joanne and Peter, have also spoken publicly, saying they are concerned and have had no confirmation of his welfare.
“We are very proud of Zack’s courage and humanity,” his mother said.
“However, we’re extremely worried about his safety.”
His father said Mr Schofield had previously been detained and held in what he described as inhumane conditions, where he allegedly witnessed mistreatment of others.
“He was abused and witnessed his colleagues, being brutally beaten,” he added.
The family has criticised the Australian Government’s response, saying humanitarian aid missions are protected under international law and calling for stronger diplomatic action.
“This is outrageous,” Peter said.
The Department of Foreign Affairs and Trade admitted it was urgently seeking confirmation of the Australians’ welfare and had no contact with those detained since Monday evening.
It reiterated expectations that detainees are treated in line with international norms.

Former flotilla participant Ethan Floyd recently stated the interception was unlawful and accused the Australian Government of failing to act.
“For the second time in as many months, Australian citizens have been illegally abducted in international waters,” he said.
The situation has also drawn international attention, with 10 countries including Türkiye, Spain, Brazil and Indonesia issuing a joint statement condemning Israel’s interception of the flotilla and expressing concern for civilian safety.
There has been no public statement from Prime Minister Anthony Albanese, while Foreign Minister Penny Wong has been urged by advocates to directly raise the issue with Israeli officials.
As of Wednesday 20 May, Mr Schofield’s location remains unknown, with families and supporters continuing to seek urgent confirmation of his wellbeing.
