Two teenagers and a child are among the Australians still missing following the eruption of a volcano on White Island, off the coast of New Zealand on Monday.
A 15-year-old girl named Zoe Hosking from Adelaide, a 12-year-old boy from Western Australia, and a seven-year-old from an unknown Australian residence are the youngest in an extensive list of people unaccounted for in the wake of the tragedy.
Their names are featured on the New Zealand Red Cross website Restoring Family Links, registered by family or friends with fears they might be caught up in the disaster.
The website allows families to register their concern for people they believe could have been involved.
Adelaide Year 9 student Zoe Hosking was confirmed missing along with her family in a statement released by her school St Aloysius College on Tuesday.
Lawyer Gavin Dallow, 53, his partner Lisa Hosking, also known as Lisa Dallow, 48, and their daughter Zoe Hosking, 15, were on a two-week Royal Caribbean cruise that left last Wednesday.
“Information is scant at this time but SAC is now seeking to provide preliminary advice to the school community,” the statement, shared by Nine News, read.
Rotary Adelaide also confirmed Gavin, a long-standing member, and his family were missing following the eruption.
However, it was confirmed on Tuesday evening by the Dallow family that Mrs Dallow is recovering in a Hamilton hospital.
Mr Dallow's father, Brian, said they trio were on the island when the volcano erupted on Monday.
The three were on a tour of White Island with 21 other Australians when the active volcano erupted, spewing smoke, ash and debris thousands of metres into the air.
A family of four from North Sydney are also among Australians who feature on the list as missing; Anthony and Kristine Langford, and their two kids Jesse, 19, and Winona, 17.
Another Australian couple yet to register their safety are Amy Miall, 30, from Brisbane and Mathew Thomas, 31, from Tamworth.
Brisbane woman Julie Richards, 47, and her daughter Jessica, 20, are also missing in the wake of the catastrophe.
There's been no word about the pair, despite checks with New Zealand police and the pair's cruise company.
Family of the pair told the ABC they were on the cruise liner Ovation of the Seas and had taken a tour to see the active volcano when it erupted.
North Queensland man Robert Rogers, 78, from Herberton, is also believed missing.
There were 24 Australians visiting from the cruise ship Ovation of the Seas, the Australian government said on Monday night.
As of Tuesday morning, five people were confirmed dead, 31 were injured and eight were still missing.
White Island tour guide Hayden Marshall-Inman, from New Zealand, was confirmed one of the people who died in the eruption by his family on social media.
“Friends and family, very sad news this evening. My bro Hayden Marshall-Inman has past away doing the one thing he loved. Thanks for all your messages. I’ll be in touch when we know more,” a relative wrote to Facebook on Monday.
Australians that have listed themselves on the Family Links site as alive include, Maree Fish from Brisbane, Eloise Kirk from NSW, and Ian Jorgensen from Penrith in NSW.
So far, five people have been confirmed dead, and it's believed up to three of those people are Australians, although this has not been confirmed.
Another eight, all believed to be Australians, are missing or unaccounted for. Some 34 people, including 13 Australians, were rescued and taken to hospital suffering burns.
Newlyweds from Brisbane are now accounted for after being feared missing among more than 20 Australians affected by the volcanic eruption on New Zealand’s White Island.
Young couple James Whitehouse, 23, and Madeleine Whitehouse, 24, were on the Ovation of the Seas cruise ship travelling off the coast of New Zealand on Monday when the volcano erupted.
Ms Ardern, speaking from the nearby town of Whakatane on Tuesday, has been in regular contact overnight with Prime Minister Scott Morrison.
"To those who have lost or are missing family and friends, we share in your unfathomable grief at this moment in time and in your sorrow," Ms Ardern said.
"Our duty is to return loved ones and ... there is much work to be done."
White Island, also known as Whakaari, erupted at 2.11pm local time (1211 AEDT) on Monday sending plumes of ash and debris more than 3,600 metres into the air while 47 people in two groups were on site.
