Not true, legislation must still be passed by the Assembly (just like in the states), it is just that the legislation can be overruled by the Commonwealth (which is what happened with the euthanasia legislation passed by the NT Assembly) - regulations merely need to be tabled in the Parliament, which is exactly what happens in the states (and with the Commonwealth as well).
The NT Liquor Act can be found
here. I am suspecting that it is a specific condition of the liquor license granted to a venue which prevents alcohol being sold to non-guests, rather than a blanket prohibition.
(As an aside, I really wish you would check your facts before posting, number_6 - you get things wrong more often than you get things right).
