Given the flow on from all of these retirements do you reckon a Dash 8 F/O (or similar low time pilot) in the US even needs to come to Australia? So a handful (or even less) from Hawaii isn't going to even dent the demand that Aussie regionals and majors have for pilots over the next few years. Quite the opposite given the numbers from above. Aussie pilots can expect to be offered gigs in the US and if they get desperate, they'll start offering $$$ as well.
