What will actually happen to parcels posted after 1st July that don't have GST collected on them?
Will they be stopped at the border? (seems like an expensive exercise to me)

Will gifts be required to pay GST too?
What's to stop someone getting a friend in another country to purchase and ship for them to avoid the hassle?

I don't mind paying GST on things I can't get here; my issue is restricting people from having choice because of its implementation.
