Unlikely, they haven't refunded my booking for domestic flights from March 2020. They insisted on issuing a voucher to be used before Feb 2022, yet I am in the UK and cannot travel to Australia and use the voucher which is restricted to the same named passengers on another domestic booking.
UK office of Qantas is largely unreachable, I am told I need to contact Australia since my booking was on the Australian website (as it has to be to book only domestic flights).
QF will have held my cash for 2 years before I can get the credit card to undertake a charge back, since they don't consider the service as not having been provided because I have a voucher.
