While this weekend's season-opening race at Albert Park is not under threat, F1 officials chartered flights for around 1500 personnel - including team staff, race organisers, officials, media and hospitality, The Athletic reported.
"You're talking about teams, drivers, Formula 1 personnel," Australian GP CEO Travis Auld told Nine's Today show.
"I'm guessing there'd be close to 1000 people that would have already booked their flights and would be landing somewhere between sort of today, tomorrow, Wednesday.
"So they had to all be changed, but a lot of people around the world are on the same thing and so you're competing obviously with that increase in demand. But they've been able to sort it out is the important part."
All equipment needed to conduct the race had already been sent to Melbourne ahead of the attacks, he confirmed.
"All the freight is here and ready to go and so we're in a space where we're really confident there'll be no impact (on the race by the travel disruption from the conflict)," Auld added. "The drivers will be here, the engineers will be here, the team principals will be here - they're the ones that have been prioritised."
There are also concerns mounting over whether next month's Bahrain and Saudi Arabia races will be able to go ahead.

"Safety and wellbeing will guide our decisions as we assess the forthcoming events scheduled there for the World Endurance Championship and the Formula One World Championship."
