Police investigating the disappearance of Gatton teenager Jayde Kendall say her bank account was accessed at an ATM twice on the day she disappeared.

Jayde has not been seen since she was picked up by an 18-year-old friend outside Lockyer District High School in Gatton, west of Brisbane, at 3.15pm on Friday August 14.

The friend has co-operated with police and his red 2003 Toyota Corolla hatchback has been forensically examined.

The car she was seen travelling in.

Police revealed today that her bank account was accessed at an ATM on Railway Street in Gatton at 5.45pm and 5.47pm on the same day.

They say they believe the movements of the red Corolla are key to their investigation.

Acting Detective Inspector Matt Howard urged anyone who may have seen the car to contact police

“Jayde’s account was accessed at the Commonwealth Bank at Railway Street at 5.45pm and 5.47pm. We are urging anyone who may have seen Jayde or the vehicle of interest at that time to contact Crime Stoppers," he said.

“We are also asking landowners in and around the Gatton area to search their properties, and alert police to anything unusual – even something as seemingly insignificant as a gate left open."

The car is distinctive with faded and damaged paint on the roof, a missing left rear hubcap and faded/dulled headlights.

Detectives are expected to publicly release CCTV related to the case later today.

Yesterday Jayde's uncle, Craig Morrissey, told a press conference that although it was out of character for her, he hoped his niece had run away.

But if someone was holding her against her will, he had a clear message for them.

"Have a bit of human decency," he said.
