I personally don't see the problem, is the job being offered better than what you have (not HAD!), can you justify some short term pain for what ultimately would be an outstanding job, if you can good luck. Should the idea of you taking this job somehow effect a QF pilots salary and conditions,I doubt it but who cares.Your primary reason should be that its good for you and your circumstances.
Is this sort of attitude going to destroy our pay & conditions, to late dont you think. Is it going to create ALOT more jobs for pilots, absolutely!
Go hard or go home
