From my understanding, my other lawyer colleagues say that this is possible. The Law Society will check the lawyer for "reference of qualification" (may not be the exact term) but basically as long as the lawyer is competent in the area of law, it may be fine.
To be fair, my information is QLD to NSW but I would imagine it works both ways. I can't think of a reason why it would be one sided.
Hope it helps. Thanks for the good question.
