Certainly some were - I saw not too long ago a medallion engraved by a first fleet convict was sold; the engraver was on the ship because of his engraving skills, which he had used to make dies for striking coins and plates for printing banknotes and other negotiable documents. I seem to remember that he came to a sticky end (on a rope) only a few months after landing, when it became apparent that he had not reformed.
I have also heard of a skilled mason being transported because he was convicted of having too many wives; in this case his skill was irrelevant to his conviction.
I am sure there were other cases of skilled workmen being transported.
