In my attempt to be brief, I guess I omitted some details pertinent to my question, as follows:
We are on the April Auckland-to-Sydney Saphire Princess cruise and so will be arriving at 0600 in Sydney at the Circular Quay dock. However, we will be staying in Sydney for the day, and then flying out late (1930) to Cairns. We would thus need to have our baggage with us and not sent on to the airport at disenbarkment. From reading earlier responses, it appears that we will clear Australian customs in Hobart. However, Princess indicated that the Overseas Passenger Terminal at Sydney will be used for the arrival, but they have been unclear/duplicative with details. Any clarifications of the process used for getting bags off the ship and claiming them on the dock is what I'm seeking.
