Australians are receiving medical treatment and showering for the first time in days, after being detained by Israeli forces while trying to sail aid into Gaza.
More than 400 people in a global flotilla - including 11 Australians - have been released after being intercepted by Israeli forces at gunpoint in international waters on Tuesday.
Australians on board the flotilla allege they were denied food and water and physically assaulted.
"Beyond all of that pain, there's a moral clarity here for all of us, which is our mission had pure intention to get food and aid unencumbered straight to Gaza," Australian activist Zack Schofield told AAP from Istanbul, where freed activists have been taken.
"We didn't succeed in that mission, but we succeeded in showing the world the depths to which Israel is willing to go to - and to brag about - to stop that from happening."
