Koala carer Sam Longman said she is still holding out hope for the safe return of her three joeys, after they were stolen from her home sometime between Thursday night and Friday morning.
Ms Longman said she has moved her remaining koalas inside her Brisbane home with 24/7 guards since the theft.

"I just don't trust people anymore," she said.
Despite a public appeal for information regarding the animals' whereabouts, there were no fresh leads over the weekend and the koala carer of 14 years said on Monday that "it's becoming quite desperate".

"By now they will be very dehydrated and their medical condition will also be worsening at this stage," she said.
An $8,000 reward has been offered for any information leading to the koalas' safe return, and Ms Longman said after extensive searching herself all she could do was sit and wait.
"All it takes is for one person to come forward anonymously."
Ms Longman was in the middle of selling her Ormiston house and moving when the theft took place, and held an open home the day before the animals disappeared. She thought it was "a bit of a coincidence" that the animals vanished overnight after Thursday's open house.
The joeys' theft hadn't just affected their carer. Ms Longman said all of the other koalas in her care had been really quiet in the two days after, with one animal in particular, who was friends with one of the missing koalas, still evidently depressed by Monday.
Despite the sad circumstances Ms Longman said she had received plenty of support from fellow wildlife carers, the RSPCA as well as family and friends.
She was also impressed by the power of strangers sharing the distressing news on social media in the hope of finding the koalas.
"I think it's amazing, it's getting the word out there and keeping it fresh in people's minds," Ms Longman said.
The two males and one female were taken from the Sleath Street home between 9pm on Thursday and 6am on Friday. Two came from North Stradbroke Island and the other from New South Wales.
Ms Longman said the animals needed daily medication as well as special milk food and it would be obvious they were in need of specialist care as they would become lethargic and one of the koalas had a visible skin condition.
The RSPCA said if the person or people responsible for the theft were caught, they could be facing animal cruelty charges.
RSPCA Queensland spokesman Michael Beatty said the kidnapper would have to know they were jeopardising the health of the koalas, who were aged between 14 and 20 months old.
"There has been blanket publicity about their need for medication and supplementary feeding," he said in a statement on Monday.
"These animals will die if they're not returned. Whoever took them must realise that."
Mr Beatty said animal cruelty charges carry a maximum penalty of three years' jail and a $220,000 fine.
Whoever took the koala joeys has been urged to hand them into a veterinary surgery, the RSPCA or a local police station.
Anyone with information regarding the theft of the joeys can call the RSPCA on 1300 ANIMAL, Policelink via 131 444 or Crime Stoppers on 1800 333 000.
