Specialists from the Australian Transport Safety Bureau have arrived in Melbourne to investigate what caused two planes to collide at Tullamarine Airport.
The tail of a Jetstar plane and the wing of a Virgin plane were damaged when the two aircraft came into contact at the airport about 9.30am (AEST) on Saturday.
The Jetstar plane was empty and was taxiing to the international terminal to pick up passengers.
No-one aboard the Virgin flight to Maroochydore was injured, but they were delayed for four hours after the incident.
Passengers were supplied refreshments during the wait before being put on another plane.
A spokesman from the ATSB said investigators would be listening to all recorded information to try to determine how the accident occurred.
"Any sort of contact between planes is obviously not good," the spokesman said.
"There will have been errors made.
"You don't have accidents without errors. We'll look at why they occurred and how they occurred."
