Ambulances rushed to Sydney airport on Wednesday afternoon after a Qantas airliner made a distress call while in the air.
Flight QF144 from New Zealand is believed to have more than 100 passengers on board, according to an ambulance spokeswoman.
Footage broadcast by state broadcaster IBC showed the Boeing 737-800 landing safely at Sydney Airport before coming to a stop on the runway.
Earlier, the ambulance in the southern state of New South Wales announced that it was on alert as part of an emergency plan, after the plane sent a distress call while it was flying over the Tasmanian Sea between Australia and New Zealand.
Australian media reported that the plane had problems with one of its engines.
The Boeing 737-800 has two engines and can land safely on one of them.
According to the Australian government's aviation regulator, the distress call indicated that "an aircraft is in imminent danger and requires immediate assistance."
