Baggage handlers, ramp workers and cabin cleaners at airports including Sydney, Melbourne, Brisbane, Perth, Adelaide, Darwin, Cairns, Townsville, Alice Springs and Canberra will lose their jobs.
The move to outsource about 2500 jobs was first revealed in August.
The outsourcing cuts come on top of 6000 already announced redundancies across Qantas' workforce, revealed in June.
Qantas has now cut about 8500 jobs, out of a pre-Covid workforce of 29,000, due to international travel bans and state border closures.
