So why are an increasing number of owners and breeders flying their prized pets across the planet at such a massive cost -- and potential risk to their performance?
"It's very tempting from an international prize money point of view," Burke said.
"Hong Kong and Dubai in particular have been pioneers in trying to push an international horse racing circuit. To say 'we're attracting the best race horses from across the world' gets major publicity for their event."
The prestige associated with an internationally recognized race horse can also boost their breeding value after they leave the track.
"We thought we had a world class horse who deserved to perform on a world class stage -- it wasn't about prize money for us," Madden said of the decision to fly Black Caviar to Ascot.
"I think a lot of owners compete their horses internationally out of a mixture of pride, excitement and business acumen."
Sometimes though, no matter how much you prepare for a plane journey, there are some hiccups you can't avoid.
"One time in Sydney we were loading breeding studs aboard a Boeing 747 bound for Europe," Burke explained.
"It was going down the runway when all the rumbling must have set off the alarms on some of the Volkswagens which were also being transported."
Unsurprisingly, "the horses didn't like the idea of that," and the plane was promptly turned around and the car batteries cut off.
After all, as Burke explained: "The horses were worth a lot more than the cars on board."
