I'm guessing the extremely expensive Norwegian labour costs make that viable? In Ireland, I never heard of sheep shearers being brought in from Australia or New Zealand (in fact the flow of young workers has been in the other direction since the 2008 crash).
My understanding was that the sheep shearers were specialists and the others were cheap labor.
Note that Norway has strict laws and regulations when it comes to wages, but especially this year it has become clear that certain farms finds all kinds of ways to fleece some of these people anyway:
- rent out overpriced "flats" with bunk beds that are the bare minimum allowed standard
- changing terms after people arrive
- generally try to skirt regulations in every way possible
