Apparently Carnival has discovered a couple of things re Aussies and may I add these are not just Aussie characteristics:
Tipping is not part of the Aussie culture therefore while the Carnival Spirit is deployed in Oz - there will be no tipping on board.
More importantly, JMHO, they recognise that the coffee has to be improved so they are going to employ Australian baristas to make flat whites.
