The specially configured Airbus A350-1000 will feature an additional 20,000-litre fuel tank, enabling it to fly for up to 22 hours without refuelling.
The first aircraft is currently under construction in Toulouse, with its main components assembled, and test flights are scheduled to commence in 2026.
The plane will be fitted with only 238 seats, significantly fewer than its 480-passenger capacity, to offer a premium experience and reduce journey times by up to four hours.
Qantas expects fares to be around 20 per cent higher, and the airline confirms that the ban on Russian airspace will not impede the route, with Arctic traversals being a potential option.
