Mr Jasson was stopped as he was about to board the flight from Melbourne to London last Friday
The T-shift features an image of President George W Bush, along with the slogan "World's Number One Terrorist.
After clearing the international security checks at Melbourne Airport, he reportedly approached the gate manager to congratulate him on the company's new-found open-mindedness.
At that point, Mr Jasson was ordered to remove the T-shirt after being told it was a security threat and an item which might cause offence to other passengers.
He was offered the chance to board the flight wearing different clothing, but refused.
A Qantas spokesman defended the airline's decision, saying: "Whether made verbally or on a T-shirt, comments with the potential to offend other customers or threaten the security of a Qantas group aircraft will not be tolerated

~The Aussies got our backs! USA! USA! USA!
If Australia's airlines and secret police maintain "no-fly lists", Mr. Jasson may never fly again?
Do flights from Melbourne to London refuel in LA or fly over America's airspace? Was that the problem?
~Google Image links to two "World's Number One Terrorist" i.e. bush terrorist shirt images. Both too small to paste here. There's a number of images of "Bush International Terrorist" tee-Shirts for view and for sale however.

This "McVeigh" shirt photo was found there.
(Isn't it time we took this slogan back from America's nazi/militias?)
