Virgin Australia has confirmed the suspicious substance found in an overhead locker of a Onslow to Perth flight is not hazardous.
Just after 10am on Tuesday, emergency services received a triple-0 call about a white powder found on the flight.
The plane was grounded at Perth Airport and around 100 passengers relocated to a quarantine area as the substance was tested by HAZMAT officers.
Passengers have since been released from the airport.
