Australians Robert Martin and Tan Safi were part of a group of 21 human rights activists on board the boat Handala, which was intercepted by Israel’s navy on Sunday.
On Tuesday, local time, an Israeli court extended their detention until their deportation was finalised.
Lawyers for the group argue their detention is unlawful.
Israel’s government has maintained a full naval blockade of Gaza since militant group Hamas took over the strip, preventing any vessels from approaching Gaza or any Gazans from sailing out.
Since Hamas’s October 7, 2023, attacks in Israel, the Israeli military has also attacked Gazans fishing in the sea.
This month it also effectively prohibited swimming and bathing by banning Palestinians from entering the water.
