Kareela was a "K-class" ferry on Sydney Harbour. Launched in 1905, the double-ended timber-hulled steamer was built for Sydney Ferries Limited in response to the early twentieth century boom in cross-harbour ferry travel prior to the opening of the Sydney Harbour Bridge. She was the first of Sydney Ferries Limited's boats to have a fully enclosed upper deck. "Kareela" is thought to be an Australian Aboriginal word meaning "south wind".
