The previous estimate for homes destroyed by the Cudlee Creek fire was 15.

Charleston man Ron Selth, 69, was found dead at his property on Saturday and several dozen people remain injured, but there have been no further injuries or loss of life.

"Ron was a loving, optimistic and generous man, who valued his relationships with family and friends more than anything else," his family said in a statement.

The fires broke out during catastrophic conditions on Friday and remain uncontrolled.

Mr Marshall said it was a "very sad day" with "scenes of absolute devastation" as families returned to their homes to find only rubble.

"If there is any good news, there has been no further fatality in SA and there has been no further … injury to personnel here in South Australia," he said.

Fire 'going' but not spreading further

Country Fire Service (CFS) incident controller Richard de Groot said the fire had now burnt through 25,000 hectares of land.

It was still categorised as "going" but had "no forward rate of spread".

Backburning has begun in the Kangaroo Creek area, east of Castambul and Montacute, causing plumes of smoke.

"We are getting a lot of concern about the fire breaking out but it is a planned event," Mr de Groot said.

About 300 firefighters are working on the fireground, he said.

A fire ban is in place for the Mount Lofty Ranges from Monday, in severe fire danger conditions.

Cudlee Creek Road, Fox Creek Road and Gorge Road are closed to all traffic.

About 2,000 homes are still without power in the Adelaide Hills.

Memories lost forever in fire

The Lobethal home Tina Zadow shares with her mother, Christel Willner, was destroyed in the blaze.

Ms Zadow said she had spent the whole day trying not to burst into tears.

She escaped to Adelaide with her dog and some paperwork.

"I didn't take a single photo," Ms Zadow said while crying.

"The family photos, the hundreds of my dad's slides that I was going to put into digital format and give to my brothers, and the photos from Germany from both sides of my parents that they rescued from the war — they're all gone."

Her son Josh stayed to fight the fire, sleeping on the driveway because it was the only thing not burning on the property.

"It doesn't look like a house anymore," she said.

"The walls have popped off. The floor's not there. It looks like a ramshackle old place when it was a beautiful home."

Smoke haze over Adelaide

A statewide smoke advice has also been issued after a number of reports of people experiencing a strong smell of smoke across South Australia.

The CFS said light winds overnight had caused the smoke from existing bushfires to spread across the state, impacting communities some distance from the firegrounds.

The Environment Protection Authority has rated the air quality in northern Adelaide as poor and western Adelaide and the CBD as fair.

Stock and crop losses still being counted

Primary Industries and Regions South Australia deputy chief executive Mehdi Doroudi said wine grape growers had been most affected by the fire, followed by apple and pear growers.

He said it was too early to tell how significant livestock losses would be in the Adelaide Hills and on Kangaroo Island.

"Some areas have been more impacted than others," he said.

"There could be some property owners that have lost everything; there could be some property owners that have only been impacted partially."

Tilbrook Estate Wines was destroyed in the fire.

The few surviving individual bottles and cases that survived were auctioned off to help the owners, the Tilbrook family recover, raising $12,000.

Co-owner Annabelle Tilbrook's colleagues at Novita stunned the crowd with a bid of $5,000 for one case before immediately donating it back for an upcoming online auction.

Golding Wines in Lobethal said in a Facebook post that while some of its structures had survived, its vineyard had sustained a lot of damage.

"Other areas of our property, including our secluded patch of bushland where we located our Nido Experience, have been burnt almost beyond recognition," the post read.

The Lobethal Christmas Pageant planned for Monday has been cancelled.
