A Qantas spokeswoman said Qantas flight QF19, a Boeing 767-300 with 200 passengers on board, "landed without incident after the captain became aware that the aircraft had a hydraulic leak".
"On inspection, engineers determined that fluid was coming from the spoiler actuator that was not evident before departure," the spokeswoman told AAP.
"There was no safety issue at any time."
