It was certainly a surprise to note that QantasLink (Cobham Aviation) Boeing B717-200 VH-NXO diverted to Longreach while operating the QJE1780 service from Brisbane to Mount Isa. It appears that VH-NXO was overhead Mount Isa and held at 14000 feet for sometime before being forced to divert to Longreach.
After around 90 minutes on the ground, VH-NXO eventually continued to Mount Isa as QJE1780 before landing successfully. It then operated a somewhat delayed QJE1781 service back to Brisbane.
Meanwhile, on Sunday 31 January, it appears that there were no commercial flights in or out of Moranbah Airport. I noted that the afternoon QantasLink Dash-8-Q400 operated service from Brisbane - QLK2464 operated by VH-QON - landed at Mackay, while the Virgin Australia ATR 72 operated service from Brisbane - VOZ1671 operated by VH-VPJ - landed at Rockhampton. Both flights eventually returned to Brisbane.
