Some time back the ADF were in a huff that it needed to be provided by an Australian flagged carrier, it was offered to both VA (330) and QF (747 as RR powered machines were being retired) and both majors turned the job down. I know that two other local carriers seriously looked at the job but at the time everyone was told that the ADF would only offer 1 year contracts as they expected the KC-30 to take on the role and swap out the tanker aircraft supporting the Wedgetail and Superbug and others.
As it was short term no one would commit to the set up costs and ADF had no choice to continue using HiFly with some CC provided by Alliance. Plans obviously changed and the KC-30 never took on the job. 5 years later Adagold are still creaming it and the Australian companies that were offered the gig are not getting any benefit.
