The airline said Friday it would not take delivery of the A380s as scheduled in 2013. That would help it cut capital expenditure by $400 million.
Instead, the double-decker superjumbos will arrive during the 2016-17 fiscal year.
Qantas in February deferred for six months the delivery of the first of 50 Boeing 787 Dreamliners it had ordered. That was part of a $700 million capital expenditure reduction. The planes are now due to arrive in mid-2013.
The announcement comes as rival Virgin Australia prepares to bring three wide-bodied Airbus A330s into its fleet by the end of 2012.
