The testing of the new system - in conjunction with Qantas - aims to reduce the time it takes to check-in, drop off luggage, access the lounge and board the plane.
Sydney Airport's CEO Geoff Culbert said in a statement: "We're very excited that select Qantas passengers now have the chance to experience this highly sophisticated technology as part of this landmark trial.
"In the future, there will be no more juggling passports and bags at check-in and digging through pockets or smartphones to show your boarding pass - your face will be your passport and your boarding pass at every step of the process."
Meanwhile, Qantas' chief customer officer Vanessa Hudson urged airlines to offer "faster and more convenient airport experiences", and added that the company is "excited to see what results the trial produces".
Initially, the trial will only be available on select international flights operated by the airline, which is the flag carrier of Australia.
However, the announcement comes after London Metropolitan Police admitted while it will continue to use facial recognition technology, it doesn't expect great results.
It has been reported that the software used by the Met Police returned false results in 98 percent of cases.
