These sea planes are at the Rose Bay Water Airport, in the eastern suburb of Rose Bay. Sydney Seaplanes is Australia's largest seaplane operator with flights over Sydney Harbour and a number of destinations like Palm Beach, Whale Beach, Cottage Point, Berowra Waters, Pittwater and the Hawkesbury River. This photo was taken fifteen years ago so this terminal has been upgraded since then.
