well i am not on the mailing list but apparently its some social group that was originally for Melbourne Commuters and expanded when the melbourne base opened.
I think that the majority of the email recipients are in Melbourne Base and seem to be very unhappy with the current rostering arrangements.
It always amuses me that some people get a base where they live so they dont HAVE to commute but still want the trips that they got out of Sydney and pressure the Company to give them what they consider is "their" fair share of the flying
Hence the pressure on the Company by these people to give them London Flying that many crew in SYdney have built their lives around
No one owns the flying and that includes Sydney but it seems a little bizarre to get the base opened in Melb and not be satisfied with the benefit of that but to want to destroy the conditions of others
