'It was terrible': Passengers hit out at cruise staff over response to volcano tragedy

A father has slammed the response from cruise ship staff in the wake of the deadly White Island volcano eruption as he and other passengers returned to Sydney on Monday morning.

There were emotional scenes at Circular Quay as tearful passengers arrived on the Ovation of the Seas after their tragic cruise to New Zealand.

Some 47 people were on the island when the volcano erupted a week ago, many of them were passengers from the cruise ship taking a tour of the island.

Two deaths on the weekend brought the official toll from the blast to 16. Ten of those victims were Australian.

‘Terrible’ response from captain and crew

Some people were visibly upset as they disembarked, with one father, who wished not to be named, said the people on the ship were left in the dark as the tragedy unfolded.

"I've got a son that's 17 who lost two friends that he made. We didn't know how many people were missing," he told reporters.

The man slammed the way the cruise ship handled the way the situation.

“The worst thing is the way Royal Caribbean handled this. It was terrible," he told news.com.au.

"The captain didn’t even tell us what was happening. We had to watch the news. It was a prison ship in the end, you weren’t allowed to know anything."

He showed reporters an information sheet about mental health handed to his family on the day prior to disembarking the ship.

The father said his son was “not OK” and was seeking medical help late last night.

Another passenger called Joanne was tearful as she talked to reporters at Circular Quay about the passengers who didn't come home.

"They're people, people that went on my holiday of a lifetime that I've waited 50 years for and they never got to come home ... dreadful."

She told how she had been upset seeing suitcases being removed from the ship.

"(It) just broke my heart," she said.

Others praised the ship's crew for their handling of the situation.
