Kurraba and Kirribilli were two similar "K-class" ferries on Sydney Harbour. Launched in 1899 and 1900 respectively, the two timber-hulled steamers were built for Sydney Ferries Limited during the boom in cross-harbour ferry travel prior to the opening of the Sydney Harbour Bridge. Built for, and initially used on, the short but busy cross-harbour route between Circular Quay and Milsons Point, they were also used frequently on the Mosman route. Along with 17 others, the two ferries were sold for breaking up in 1934 following the opening of the Sydney Harbour Bridge in 1932.
