I'd like him to expand on his points tbh. I mean exactly why would it be a less attractive place? We can offer whatever attractive business rates/packages we want and any experts in fields who live in the EU are not suddenly going to find an impassable wall even if we did get an Aussie style system, I know quite a few people who now live in Aus who too be honest, don't strike me as experts in any field who could offer all that much, and many didn't even have a job to go to.
Still undecided myself...less than a week to go.
