A Queensland woman missing in South Australia's western Eyre Peninsula for seven days has been found.

SA Police said the woman, Julie Schutt, was found north-west of Streaky Bay this morning and was "currently receiving medical treatment".

Superintendent Paul Bahr said police received a call just after 8am on Sunday from a member of the public who was north-west of Streaky Bay to say they had found a person "wandering out of the scrub" asking for water.

"We had a search vehicle nearby, they attended, they located the woman and identified her as the missing woman Julie," Superintendent Paul Bahr said.

"She is safe and well, although requiring perhaps some medical attention.

"It appears she has been in the scrub for some time."

Julie was last seen a week ago in Streaky Bay, after travelling to the town with her husband on holidays. 

Julie's brother, Todd, said he was feeling "so grateful" and his family were "relieved".

"It's so good to have her back," he said.

"I can't thank everybody enough who has helped in the search for Julie."

Todd said his 48-year-old sister was recovering in hospital.

"Julie's obviously dehydrated and she hasn't eaten or had a drink for over six days, so she's got a little bit of recovery to do," he said.

Julie's husband, Clifford, said she was in "surprisingly really good health" given the circumstances.

He said doctors were unsure how long Julie would need to be in hospital for.

"She's very tired, she's sore, she's done a lot of walking. We just have to see how she recovers," he said.

Clifford also thanked the community of Streaky Bay for all their assistance in the search.

"It was the best outcome we could hope for," he said.

Clifford said he "lost the plot" when he received the phone call from police saying his wife had been found.

"I broke down, and just had to gather myself after a few minutes," he said.

Superintendent Bahr said the result was "good news" after "quite a long" search.

"It's been going now for seven days. To have a positive outcome is a great piece of news," he said.

Police had repeatedly appealed for public assistance as they searched Streaky Bay and the surrounding areas.

On Thursday afternoon, police confirmed the search had been scaled back, but would continue "over the following days using local police and volunteers".

Superintendent Bahr thanked State Emergency Service and Country Fire Service volunteers who worked "tirelessly" during the search.

Superintendent Bahr said it was unclear what happened and how the woman had survived the seven days.

"We'd be keen to talk to Julie at some stage when she's ready and how she managed to survive and where she was," he said.
