Bli Bli is a locality and hamlet on the Sunshine Coast, Queensland, Australia. A few kilometres inland from the Maroochydore urban area, Bli Bli rises above the wetlands which were, for many years, the home of the Sunshine Coast sugar cane industry. Whilst this industry is all but gone, state government legislation ensures the wetlands will remain an undeveloped "Green Space" (See Qld Plan). At the 2006 census, Bli Bli had a population of 5,345. From the early 1970s until recent times, Bli Bli was most notable for the "fairy tale" castle that has been built as a tourist attraction in the village. The Castle now houses medieval paraphernalia as well as a large doll display and coffee shop. Today Bli Bli has become a conveniently located residential community, it retains its small-town feel, yet is minutes from Sunshine Plaza in Maroochydore, Mudjimba Beach and the Bruce Highway.
