Qantas Airways, which suspended its mainline operations on Friday, over labour issues, has resumed operations. Fair Work Australia has ruled the airline and its unions to resume work. The resumption is still subject to final approval.
One of the first flights to resume operations would be QF32, operating as QF8032, on the Singapore - Sydney sector. The airline is requesting passengers for this flight and some other international flights to travel to the airports.
This breaking post will be updated soon.

Passengers on QF8032 have since been told to disembark the Qantas aircraft after being seated for around an hour. So looks like the planes are still grounded.
