Activists on board a flotilla of vessels sailing toward Gaza say they are are prepared for the Israel navy to intervene as they approach the besieged Palestinian territory, after a tense night in the Mediterranean Sea.

The Global Sumud Flotilla, with Greta Thunberg aboard, consists of about 50 boats and 500 activists from 44 nations, including at least six Australians involved.

"I can't even begin to put into words how it feels," Sydney content creator Abubakir Rafiq, who is aboard Spectre , said in an Instagram post.

"It's so close and everything has led to this moment right here, the final hours, the final part of the journey."

Rafiq said the flotilla hoped to "break the siege" and "announce that this humanitarian corridor has opened up" as a result of their efforts.
