It comes after the airline reportedly received negative local media coverage following a spate of flight delays, cancellations, lost baggage and staffing issues.
In response, the carrier said on Sunday (21 August) it would send frequent flyer members an email and video message on Monday (22 August) from its chief executive Alan Joyce.
"On behalf of the national carrier I want to apologise and assure you we are working hard to get back to our best," Joyce said in the video message.
According to Reuters, Qantas will also offer vouchers, loyalty status extensions and lounge passes to frequent flyers to apologise for the recent issues.
It said it will implement a "range of initiatives" to improve on-time performance and mishandled baggage as it also dealt with high levels of staff sick leave and an industry-wide labour shortage. The carrier said it had hired 1,500 new people since April.
