Four-year-old Cleo Smith - who went missing last month - has been found alive and well by Western Australia police officers.
Cleo hadn't been seen since about 1:30am (local time) on October 16, in her family's tent at a remote campsite about 900km north of Perth. When her parents woke at 6:30am she was gone.
In a statement on Wednesday, deputy Western Australia Police Commissioner Col Blanch said it was "my privilege" to announce Cleo was rescued in the early hours of the morning.
"Cleo is alive and well," Blanch said. "A police team broke their way into a locked house in Carnarvon about 1am.
"They found little Cleo in one of the rooms.
"I can confirm we have a man from Carnarvon in custody who is currently being questioned by detectives."
Cleo's disapperance last month sparked a nationwide search, with an AU$1 million (NZ$1.04m) reward offered for information about her disappearance. There were more than 1000 tip-offs from members of the public in that time.
The young girl said "my name is Cleo" when she was picked up by a police officer on Wednesday morning, Blanch said. She was reunited with her parents a short time later.
"This is the outcome we all hoped and prayed for," Blanch said.
"It's the outcome we've achieved because of some incredible police work."
Last week, Cleo's parents issued a televised plea to the person who kidnapped her.
"If you know anything, anything at all, we want our daughter back," mum Ellie Smith said.
"We have hope that our girl is there somewhere but we don't have any leads."
Police had previously said it was believed Cleo was still in Western Australia.
"I want to thank Cleo's parents, the Western Australian community and the many volunteers," Blanch said on Wednesday.
Australia Prime Minister Scott Morrison, currently at the COP26 climate conference in the UK, said it was "wonderful, relieving news".
"Our prayers answered," he said on Twitter. "Thank you to the many police officers involved and supporting her family."
Blanch said more details about Cleo's rescue would be released later in the day.
"For now - welcome home Cleo."
