Everyone on Ambae, in the north of the Pacific archipelago, was ordered to leave after the Manaro Voui volcano rumbled to life and rained rock and ash on villages last week.
Fearing a major eruption, officials mobilised a rag-tag armada of civilian vessels to ferry residents to safety on other islands, with at least 18 evacuation centres set up in schools, churches and on sports grounds.
"The evacuation of the residents of Ambae Island -- approximately 11,600 people -- is now complete," said Australian Foreign Minister Julie Bishop.
"Tents for temporary shelter, kitchen supplies and lighting will provide relief to families and improve community safety," said Bishop, adding that access to clean water was also being provided.
Vanuatu's official Geohazards Observatory said on Tuesday the threat had eased, although it continued to maintain the volcano's status as level four on Thursday, the second-highest rating.
