The air force has grounded 35 multi-fighter jets amid an investigation into why two pilots were forced to eject from a Super Hornet during take-off.
The two crew safely ejected from the US-built fighter jet, which then crashed, about 2.30pm on Tuesday at Amberley air base in Queensland.
Defence Minister Linda Reynolds said the fleet of 24 F/A-18F Super Hornets and 11 EA-18G Growlers have been grounded indefinitely during an investigation into the accident.
"When I heard about the incident my first thoughts obviously was for the crew who, fortunately, I'm happy to report, are doing well," she told reporters on Wednesday.
"But we have grounded the Growler and also the Super Hornet fleet for an abundance of caution while investigations occur into the incident yesterday."
There has been some speculation that the accident occurred after the Super Hornet's nose landing gear collapsed.
Royal Australian Air Force Air Marshal Mel Hupfeld said the investigation would reveal the cause of the crash during "one of the most critical points or phases of flight".
"It's too early for me to surmise on those things," he said.
"I was discussing this with my wife last night, I'll give you the same answer: This is a sophisticated machinery. I've got thousands of (flying) hours on the classic Hornet and I'm not going to surmise on the cause of this incident.
"There are many things that we pull together to operate a (plane) like this. This needs to undergo a suitable level of investigation to get the right answers so that we can provide the right solutions."
Defence will wait for the safety investigation team's report before making a decision about redeploying the aircraft.
The investigation findings will also be shared with other nations that operate the warplanes.
The United States is the only other nation that uses the Growler, but both the US and Kuwait operate F/A-18F Super Hornets.
The Hornet, which Boeing sells for about $US66 million ($A89.5 million) each, has been in operation for eight years and is Australia's primary strike fighter.
The Growler is a specialised version of the Hornet that can engage in electronic warfare and cost about $US68.2 million ($A98 million).
A RAAF Growler was destroyed after catching fire due to an engine malfunction during a training exercise at the Nellis Air Force Base in Nevada in July 2018.
RAAF's F/A-18A/B Classic Hornet and F-35A Joint Strike Fighter remain in operation.
