The NSW premier is hopeful of an imminent breakthrough in the case of missing three-year-old William Tyrrell who disappeared seven years ago.
Dominic Perrottet said on Wednesday the signs and reporting coming from the police investigation were "very encouraging" and police were doing a "phenomenal" job.
He was commenting after NSW Police revealed they had seized a car linked to the case as part of their investigation.
The grey Mazda was seized from a home in Gymea in Sydney's south under a coronial order.
"The vehicle was taken to a secure facility, where it is undergoing extensive forensic examinations and analysis, which is expected to take several weeks," NSW Police said in a statement.
William went missing while wearing his Spider-Man suit and playing at his foster grandmother's home in 2014, in a case that has attracted national attention.

It's the third day of a renewed search for the remains of the boy that has seen officers comb the mid-north coast property where he was last seen.
NSW Police deputy commissioner Malcolm Lanyon said investigators were committed to the active investigation.
"The NSW Police will not stop until such time as we've investigated every possible lead," he told reporters on Wednesday.
Police on Tuesday dug up the garden at the Kendall home, with a mechanical sift brought to the property. They also sprayed luminol, a chemical that detects traces of blood, during the night.

In nearby bushland, volunteers cut down trees to help in the search.
Asked if police were investigating whether William died after falling from a balcony at the house, Police Minister David Elliott said every option was being considered.
"With a mysterious incident like this, every single option has to be investigated, every scenario has to be reviewed and tested," he said on Tuesday.
"Let's hope whatever the conclusion is, [it] gives closure to the families and community."
Police commissioner Mick Fuller has confirmed there has been a significant breakthrough in the case, saying he was confident police would solve the mystery of what happened to William.
"There is certainly one person in particular that we are looking closely at," he said.
The findings of a coronial inquest into William's disappearance, which concluded last year, are yet to be handed down.
A $1 million reward for information on the case still stands.
