About Fremantle Fishing Boat Harbour
In 1919, a 300 metre breakwater was constructed to provide anchorage to fishing boats in Fremantle. In 1929, the Fish Market was removed from the end of the timber jetty. A Southern breakwater was constructed in 1962, to provide a larger sheltered mooring area, increased wharf space, an additional service jetty and a dinghy mooring area. Between 1969 and 1972 the first pens were constructed to house 170 fishing boats. In 1982 land was reclaimed and the first stage of the boat lifting facility was constructed. This facility was the major fishing and marine industry refit site in the state, with boats from as far a field as Darwin and Esperance using the facility for their annual refits and surveys.
Following the Australia II winning the Americas Cup, Fremantle underwent a major redevelopment which saw the focus shift from the fishing industry, and saw the construction of retail and food outlets. Today, the Boat Harbour is a major tourism destination within Perth.
