The mother of a missing woman has vowed to never stop looking for her lost daughter as police offer a $500,000 reward in the hope it will spark someone's memory about her disappearance.
The family of Jessica Zrinski, 30, last heard from her about 10pm on November 27, 2022 from Sydney's Bossley Park area.
She was reported missing by them a few days later when they couldn't find or contact her.
Police later discovered Ms Zrinksi had been in the car park of a hotel at Greenfield Park about 10pm on Monday, November 28, before leaving in a blue Holden Commodore station wagon about 10 minutes later.
Investigators say the car travelled west on the M4 motorway and Great Western Highway towards the Blue Mountains.
On the anniversary of her disappearance, Ms Zrinksi's family joined police to announce a $500,000 reward for information that helps locate her.
Ms Zrinksi's mum Michelle Barton said she would never stop looking for her daughter.
"Living life without my baby girl Jess has been the most difficult pain I've ever had to endure," she said.
"I've loved her for her whole life and I'll miss her for the rest of mine.
"All I can hope is there is someone out there who can help us find Jess so we - her family and friends - can lay her to rest and say our goodbyes."
New CCTV footage of Ms Zrinksi in the Commodore, which was seen travelling through Horsley Park about 10.15pm on Monday and Mount Victoria on Tuesday, November 29 about 8.50am, has been released.
Any witnesses who may have seen the car in the areas at those times have been urged to contact police.
Police Minister Yasmin Catley hoped the reward and footage would encourage anyone with information to come forward while Ms Zrinksi's disappearance is fresh in people's minds.
"What happened a year ago would still feel like yesterday for Jessica's family and the people who loved her," Ms Catley said.
"As police continue their quest for truth, I ask anyone who has information about this case to come forward and assist police - before they come knocking on your door."
Homicide Squad Commander Detective Superintendent Danny Doherty said investigators would leave no stone unturned in their search for answers.
"We believe there are still people out there who have vital information about Jessica's movements on the day she was last seen, and possibly, her whereabouts; information that could help solve this case," he said.
