A huge $1million AU (£540,000) reward for finding a missing four-year-old will not be claimed, police have said.
The large sum was put on the table after Cleo Smith went missing from her tent at the Quobba Blowholes camping ground.
A taskforce of 100 officers were sent in from the state capital, Perth, to join a massive air, land and sea search.
They were joined by bounty hunters from across the country, who scoured the state in the hope of finding the young girl.
Last night, beyond most people's wildest expectations, Cleo was found in a Carnarvon home, 18 days after she disappeared.
A man was been taken into custody in relation to the disappearance.
While public figures and members of the public let out a collective sigh of relief that Cleo was found, many questions surrounding the case remain.
One of them is whether she was alone in the house when police officers found her.
When asked that question at a press conference this afternoon, Detective Superintendent Rod Wilde, the lead investigator, said he couldn't address it at this point.
He also wouldn't be drawn on where the 36-year-old suspect was found.
What does seem clear is that no one will be receiving the $1million AU reward that was up for grabs.
Acting Police Commissioner Col Blanch said: "Intelligence led them to that house. They went into that house, Cleo was in the house alone."
Asked by reporters on Wednesday whether he thought the reward would be claimed, he said: "I don’t believe so, no."
Little is known about how police came to get that intelligence, beyond their being an important tip-off on Tuesday night.
This, combined with phone data and several "forensic leads", led them to the suspect, Commissioner Chris Dawson said.
"There was some information we followed up on," he told ABC radio.
"We had been following a lot of the forensic leads and it led us to a particular house. We put everything we had at it.
"Hope was never lost and the fact she's been found alive, I think Australia is rejoicing. It is such a wonderful outcome."
Neighbours of the childless man said he'd been acting suspiciously in the days before Cleo was found and was seen buying nappies, Mail Online reports.
Police broke into a house in Carnarvon, a town about 100 km (62 miles) south of the campsite, early on Wednesday morning and found Cleo in one of the rooms.
Western Australia Police have confirmed the man arrested is not connected to Cleo's family.
Police said the abduction appears to have been opportunistic and they expect to file charges later in the day.
"She is physically OK. That was evident from the start," said state police homicide squad Senior Sergeant Cameron Blaine, who was one of four people to rescue the child.
"Taking her to the hospital we got assurance of that from people that know what they are doing."
When Cleo went missing on October 16 she was on the first night of a holiday at the Quobba Blowholes camping ground.
The remote site is 560 miles north of Perth and is known for its sea caves and lagoons.
Cleo had gone to bed for the night on an air mattress next to her sister's cot in a tent.
When her mum woke up the next day the young girl was gone and the tent door was left open.
Ms Smith was adamant that her daughter could not have left the tent by herself, instantly leading to fears that she had been abducted.
