Clontarf is a residential and light industrial suburb of the Moreton Bay Regional Council in the south-west of the Redcliffe peninsula, approximately north-northeast of Brisbane, the state capital of Queensland, Australia. It is the largest suburb in the municipal area by land area, and shares a sea border with Brisbane City Council.
Clontarf is connected to Brisbane City, across Bramble Bay, by the Houghton Highway which is a 2.7 km long causeway that provides access to the southern tip of Redcliffe City, greatly decreasing the travel time between Redcliffe and Brisbane. The Houghton Highway replaced the Hornibrook Bridge which is now used by pedestrians, cyclists and for recreational fishing.
During the past few decades, beach goers have not viewed Clontarf as a very enticing destination, due to its coast being polluted with human effluent. The environmental situation has improved, however, and Clontarf Beach and Bells Beach are two of the closest beaches to Brisbane City.
Pelican Park is known for its kite flying conditions, and a local industry has built around the sport. On weekends, many kites can be seen flying above Clontarf from the Hornibrook Bridge. During May, the Redcliffe Kite Club, based in Clontarf holds a two day kite event called Kitefest.
Clontarf's west hosts the largest industrial area in Redcliffe city, and the area is a significant source of employment for the region. Many residents of Clontarf also commute to Brisbane daily for work. Most commuters travel by car, as there is no train line into Redcliffe city.
Clontarf is host to two adjacent medium-sized shopping centres, on the southern tip of the suburb. Most retail commerce in the suburb revolves around small business however, and there are many stand alone corner stores and other small businesses still in existence.
