Two crew members have ejected from a RAAF Super Hornet jet as it crashed before taking off at the Amberley air base in Queensland.
"The aircrew of that aircraft are safe and no other personnel were involved in the incident," a Defence spokeswoman said in a statement on Tuesday.
"Defence's first priority is the safety of personnel at RAAF Base Amberley."
Footage obtained by Nine News from about 2.30pm showed the crew landing in their parachutes and the jet with its cockpit jettisoned.
The cause of the accident is unknown and an investigation is under way.
However, a defence expert said it appeared to be caused by the collapse of nose-landing gear.
