Oceania Cruises offers cruises from the US to Australia and cruises from Australia to the US. They also have cruises that circumnavigate Australia. See the complete schedule below.
Oceania calls itself an upper premium cruise line. That means they offer luxury but a little less expensively than the ultra-luxury lines. Their ships carry fewer passengers (only 684 on the Sirena) for an uncrowded, pampering voyage. They claim to have the finest cuisine at sea.
The Oceania Sirena is the ship that goes to Australia. It was refurbished and features Canyon Ranch SpaClub, casino and 6 elegant lounges. The dining options are the Grand Dining Room, Tuscan Steak, Red Ginger contemporary Asian, indoor/outdoor Terrace Cafe, casual Waves Grill, Baristas coffee bar, room service, and afternoon tea.
