Many days their MEL-MCY services are sold out. Hopefully, this gives them a bit of confidence to maybe go after some other routes served by JQ.
In the current market, selling 186 seats a day on routes JQ serve 3-4 times a day should be achievable.
MCY-Albury doing surprisingly well I hear. They are offering as a really cheap, quick option to visit the snow - something you can't do easily from SE QLD.
