Australia will be the home port for Royal Caribbean's newest billion-dollar mega-liner - Ovation of the Seas- when it arrives in December 2016, making it the biggest ever ship ever based here. The $US1 billion ($A1.3 billion) ship, currently under construction in Germany, will be the length of more than three football fields and tower at 50m tall. It will house over 18 decks and have a capacity to hold almost 5000 guests and 1500 crew members. The mega-liner will be the largest cruise ship to be based in Australia to date. Voyager of the Seas is the current title holder for the largest ship to be based in Australia. Ovation of the Seas will be based at Sydney's Overseas Passenger Terminal in Circular Quay for its maiden 2016/17 Australian summer season. Ovation of the Seas is said to 'completely redefine' the experience of cruising in Australia with features and technologies described as first-time offerings for ships worldwide.
