It seems Rex might have a bit of a problem with another SAAB. VH-ZRC flew into Julia Creek as RXA5627 on 24th March but apparently did not leave. Later that day a replacement aircraft, VH-ZRI, flew to YJLC from Brisbane and completed the balance of the rotation to Mt Isa and back to Townsville. According to both FlightAware and FR24, ZRC has not flown anywhere since. Unless the ADS-B is inoperative it might still be on the ground at YJLC more than a week later.
