Luxury cruising in Australia and New Zealand offers a sophisticated gateway to the Southern Hemisphere’s most dramatic landscapes. In 2026, premier lines like Silversea, Seabourn, and Regent Seven Seas are elevating the experience with all-inclusive "ultra-luxe" voyages. Travellers can witness the limestone majesty of the Great Barrier Reef or navigate the serene, glacial-carved fjords of Milford Sound in New Zealand. Shore excursions are deeply immersive, ranging from private helicopter tours over the Bay of Islands to exclusive tastings in the Barossa Valley vineyards.
