I understand that some people feel that way, but the sentiment is illogical. If you are a dyed in the wool Queenslander loyal to the bone, why did you leave your state? Particularly to the extent that you have built a life in New South Wales. If your ties to your state were that important to you, why weren't you willing to take a less attractive job in Queensland?
That being said, I can understand people who are in a period transient employment, such as spending a few years in the mines, retaining their parochial loyalties to their traditional state if it is their intention to move back to their former home in the short to medium term. However, if a move is permanent or at least indefinite, the only real justification I can see for retaining former loyalties like that is emotional attachment, which I argue is not logical.
An analogous example would be: I was previously an engineer but have subsequently decided to study Law. When I am practicing law, I will not be going around saying "oh yeah, I'm doing the job of a lawyer but am really an engineer". I made a choice, I accept all the consequences which go with that choice, large and small. I might accept that I am both a lawyer and an engineer, if the work that I am doing is relevant to that, but it would be foolish on my part to ignore that I am (at that point) actually a lawyer entirely.
