Gidday Meeb,
not sure why you would want to go from 737 to turboprop (why anyone would for that matter!
) but I would think you would be most welcome if you could demonstrate your willingness to do the job.
I know my company has taken at least one heavy jet qualified pilot. That person is now flying with a Queensland Regional and was not with the company very long - that may affect your employment chances somewhat possibly, but as far as having jet experience, I think that would be a big plus.
Cheers,
TJ
