The children dramatically caught in an image that symbolised Tasmania's devastating bushfires are showing few signs of the trauma they experienced, their family says.

More than a week has passed since Tim Holmes snapped a photo of his wife Tammy and five grandchildren sheltering from the state's most destructive blaze under a jetty at Dunalley.

Taken on Ms Holmes' iphone, the image went around the world and fast became the horrific symbol of fires which destroyed nearly 200 properties in Tasmania.

The five Walker children, aged from 2-11, have begun to move on, their mother Bonnie Walker told reporters at the family property on Friday.

"We haven't noticed any symptoms or signs in them of any stress or trauma, considering what they've been through," Ms Walker said.

"We're still obviously looking for signs of that but they've been great.

"They think it's fun."

The children's father David Walker said the couple expected to monitor the reactions of Matilda, who is 11, Liam (nine), Caleb (six), Esther (four) and Charlotte (two), who are all homeschooled.

"Sometimes they'll just bring something up as we're driving somewhere, it might just be a little snippet of information," Mr Walker said.

" ... We've just tried to bring some normality back into their lives as quickly as we can and they're very robust and resilient and they're doing really well."

Mr and Ms Holmes evacuated their house, just outside Dunalley, and escorted the children along the waterfront to the jetty around 500m away.

There they sheltered in cold water and waited for the massive fire front to pass.

"They stayed very calm and they were very settled and steady throughout," Mr Holmes said.

"I think the fact that we know them so well and they're very comfortable with us means that they were confident.

"We didn't tell them at any stage how serious the situation was and they just trusted us."

Mr Holmes took the photo to show the children's mother, who was out and unable to return home, that the children were safe.

"We didn't ever seek attention," he said. "That wasn't the idea.

"People in Dunalley have said to me that that photo actually helped people understand what really took place here."

The family have been unable to return to the jetty because of dangerous trees, but they do plan to go back.

"We won't go back down there with any fear or trepidation," Mr Holmes said.

"I'll be very interested to see the extent to which the jetty caught fire."

The family lost three of four dwellings and several outbuildings on their property, where they lived in adjacent houses and ran a bed and breakfast.

The clean-up has begun and they will rebuild after becoming the last in Dunalley to have their power reconnected, two weeks ahead of schedule.

"(We feel) a lot more confident about the road ahead and (we're) feeling good about what we can do on our property," Mr Walker said.

"We're really committed to this community and love being part of it."
