Qantas has emblazoned the Yes23 campaign logo on three of its aircraft to back the Indigenous voice being enshrined in the constitution.
Qantas Group chief executive Alan Joyce on Monday announced the aircraft will take to the skies with the logo, as part of the airline's longstanding commitment to reconciliation.
"We're supporting the Yes23 campaign because we believe a formal voice to government will help close the gap for First Nations people in important areas like health, education and employment," he said.
The livery will be carried on a Qantas Boeing 737, a QantasLink Dash 8 turboprop and a Jetstar Airbus A320.
Prime Minister Anthony Albanese launched the airline's 'yes' campaign in Sydney, praising Qantas for backing reconciliation since the 1960s.
"Qantas has shown the importance of extending ourselves, of reaching higher," he said.
"This 'yes' livery is a worthy addition to that tradition and it is in the spirit of Australia."
The airline is among a host of other businesses, including Australia's major banks, Wesfarmers, Woolworths, and Rio Tinto to back the 'yes' case in the voice referendum.
Australians are expected to vote in the referendum in October, with the prime minister signalling the formal start of the ballot process within weeks.
