A jetty is a structure that projects from land out into water. A jetty may serve as a breakwater , as a walkway, or both; or, in pairs, as a means of constricting a channel. The term derives from the French word jetée , "thrown", signifying something thrown out.
47-516: Picnic Bay Jetty is a heritage-listed jetty at Esplanade, Picnic Bay , Magnetic Island , City of Townsville , Queensland , Australia. It was built from 1959 to 1977. It was added to the Queensland Heritage Register on 5 April 2004. The Picnic Bay Jetty appears to be the third jetty constructed on the site. A permit to construct the facility was issued in 1957 and the structure was completed about mid October 1959. The present jetty
94-450: A depth of 22.75 feet (6.93 m). below low water of spring tides; and their solid masonry portion, on a concrete foundation was raised 50 feet (15 m). above low water of neap tides . A small tidal rise spreading tidal water over a large expanse of lagoon or inland backwater causes the influx and efflux of the tide to maintain a deep channel through a narrows no longer confined by a bank on each side, becomes dispersed, and owing to
141-758: A nomination to the Queensland Heritage Register. Members of the Island community advised Townsville Cultural Heritage staff that they had already established an "Interim Management Committee" to oversee the ongoing care of the jetty if the Queensland Government was no longer prepared to maintain the structure. The jetty is located within Picnic Bay. It extends into the Bay from the Esplanade where Yule Street meets
188-590: A place to walk for recreation or exercise and to sit looking across Cleveland Bay to the vista of Castle Hill and the Townsville skyline. The jetty is also frequently used as a mooring place for small yachts and fishing vessels. In 2001 it was announced that when new harbour facilities at Nelly Bay, Magnetic Island were completed the Picnic Bay Jetty would be removed as soon as the structure became obsolete to requirements.

The family experimented with the planting of pineapples and after building small huts adjacent to their house the island became a favourite weekend and holiday destination for mainland people. The Butler family established an intermittent ferry service at the time they began their small tourist venture. Tourist development on the island began in earnest when Robert Hayles built an hotel at Picnic Bay in 1899. Hayles arrived on
282-467: A wide channel , and by concentration of the current to produce a deepening. Jetties have been constructed on each side of the outlet river of some of the rivers flowing into the Baltic , with the objective of prolonging the scour of the river and protecting the channel from being shoaled by the littoral drift along the shore. Another application of parallel jetties is in lowering the bar in front of one of
329-625: A wooden jetty which would be six feet wide and 100 feet (30 m) long. Construction was approved by the Marine Department late in March 1900. The new jetty was damaged during Cyclone Leonta in 1903 and by 1910 was in poor condition. Correspondence indicates that Robert Hayles carried out extensive repairs to the structure. Initially, on the mainland, the company operated from existing wharves and temporary landings in Ross Creek . In 1909 Robert Hayles

The town of Alma Bay is within the suburb ( 19°08′54″S 146°52′04″E / 19.1483°S 146.8677°E / -19.1483; 146.8677 ( Alma Bay ) ). Arcadia is predominantly residential with around 97% of
423-547: Is a southeast facing skillion structure of corrugated iron. The north west wall is enclosed to provide shelter from the weather. A second shed is centrally located at the end of the Jetty. This square structure has a hipped roofline of aluminum. The covered area is split into four by central walls which have been painted with murals by children from Magnetic Island State School. Seats are located along each of these walls. A third sheltered area, which may have been part of an earlier shelter,
470-436: Is attached to the central structure. This area is the walkway to the main access stairway to the ferry. Picnic Bay Jetty was listed on the Queensland Heritage Register on 5 April 2004 having satisfied the following criteria. The place is important in demonstrating the evolution or pattern of Queensland's history. Picnic Bay Jetty, constructed by October 1959, is at least the third jetty constructed on this site.

These boats were to be the foundation of a much larger Hayles fleet that eventually operated in places such as Cairns , Darwin , Townsville , Sydney and Canberra . The introduction of a ferry service to Magnetic Island had a significant impact on

Plans, prepared by the Townsville City Council, indicated that the original location of the structure was slightly altered to allow better access for passengers. Apart from being a point of arrival and departure from the Island, the Jetty has always been a significant place for the Magnetic Island community. They have utilised it for fishing and as
799-481: The Harbour Board suggested that no further private construction of landing stages should be allowed on the Island. The Hayles' tourism business prospered and expanded. A new hotel was constructed at Picnic Bay after the first was destroyed by fire in 1911; a guesthouse and jetty were constructed at Arcadia , Magnetic Island together with tourism ventures at Nelly and Horseshoe Bays, Magnetic Island. On 13 March 1922

The company expanded to Cairns in 1924 where they provided a regular mail and cargo service between Cairns and Cooktown . The same year the company opened an office in Darwin. From there they provided a cargo service to outlying mission stations, lighthouses and to settlements along the Victoria and Daly Rivers. In August 1920 control of
940-593: The Island community. This was particularly so after the 1900 enforcement of compulsory education (first introduced in the Education Act 1875). The establishment of a regular Magnetic Island ferry service early in the twentieth century ensured that students could live on the island and travel to school each day. From this point the permanent population on the Island began to grow and more commercial businesses were established. The Hayles family tourism business continued to prosper and on 20 June 1910 Eustace Robert (Bob) Hayles

In 1898 Robert Hayles purchased the holiday facilities erected by the Butler family and constructed a two-storey hotel, dance hall and his own jetty west of that constructed by Harry Butler and close to the site of the present day jetty. In March 1900 Robert Hayles applied for permission to construct

#17330850381881034-585: The Magnetic Island foreshore was vested in the Townsville Harbour Board. While this move gave control of jetties to the Harbour Board, the Board, in June 1925, adopted a policy not to erect jetties on Magnetic Island but rather to approve the erection of shipping facilities by private developers. While the Hayles family company continued to expand with a fortnightly Cairns to Green Island Service opened in 1928 and
1081-587: The North Queensland Conservation Council and Magnetic Island community members became concerned about the proposed demolition of the jetty. On Sunday 8 July 2001 1500 people from Townsville and Magnetic Island rallied on the Picnic Bay Jetty asking that the jetty be saved. This initial rally was followed by a series of news articles, letters to the Bulletin, letters to the Minister for Transport and
1128-399: The Townsville Harbour Board approved the construction a new jetty at Picnic Bay. Tenders were called on 15 January 1959 and the jetty, constructed by John Holland (Constructions) Pty Ltd , was completed about mid October 1959. The Commonwealth Aid Marine Works Trust Fund, at a cost of £ 43,000, financed construction. It was leased to Hayles Magnetic for 20 years during which time the company
1175-513: The bar, and lower it by scour. Thus the available depth of the approach channels to Venice through the Malamocco and Lido outlets from the Venetian Lagoon have been deepened several feet (metres) over their bars by jetties of rubble, carried out across the foreshore into deep water on both sides of the channel. Other examples are provided by the long jetties extended into the sea in front of
1222-402: The bars obstructing the access to them; and they have also carried the sediment-bearing waters sufficiently far out to come under the influence of littoral currents, which, by conveying away some of the sediment, postpone the eventual formation of a fresh bar farther out (see river engineering ). Where a river is narrow near its mouth, has a generally feeble discharge and a small tidal range,
1269-498: The beach. The jetty was initially 800 feet (240 m) long; however, the 1977 extensions increased the length by about twenty feet. 160 square concrete piers, installed by a cantilever pile driver, are evenly spaced along the length of the jetty. Round piers encased in concrete were used in the construction of the assembly area at the end of the jetty. The jetty structure is made up of round timber beams topped with wide timber decking. A raised walkway, which runs along one side of
1316-427: The coast, and subsequently by the current from sluicing basins; but it is now often considerably deepened by sand-pump dredging . It is protected to some extent by the solid portion of the jetties from the inroad of sand from the adjacent beach, and from the levelling action of the waves; while the upper open portion serves to indicate the channel and to guide the vessels, if necessary (see harbor ). The bottom part of
1363-483: The docks. Solid jetties, moreover, lined with quay walls, are sometimes carried out into a wide dock, at right angles to the line of quays at the side, to enlarge the accommodation; and they also serve, when extended on a large scale from the coast of a tideless sea under shelter of an outlying breakwater, to form the basins in which vessels lie when discharging and taking in cargoes in such a port as Marseille . The approach channel to some ports situated on sandy coasts

There are no schools in Arcadia. The nearest primary school is Magnetic Island State School in neighbouring Nelly Bay to the south-west. The nearest secondary school is Townsville State High School in Railway Estate on
1457-471: The easterly drift, but the bar in front has been lowered by the scour produced by the discharge of the river following the concave bend of the southwest jetty. As the outer portion of this jetty was exposed to westerly storms from the Bay of Biscay before the outer harbour was constructed, it has been given the form and strength of a breakwater situated in shallow water. Where docks are given sloping sides, openwork timber jetties are generally carried across

Jetties have the adverse effect of endangering Surf Culture as a whole with their ability to destroy surf breaks. Arcadia, Queensland Download coordinates as: Arcadia
1551-600: The introduction of Brisbane River Cruises in 1936 the outbreak of World War II in 1939 saw shipping operations cease when the Australian military requisitioned the company fleet. The facilities at Picnic Bay were also taken over as a rest and recreation camp for service personnel. There was a period of expansion and upgrading of facilities after the company property was returned to the Hayles family in 1945. Roads, buildings and jetties were upgrades and access to jetties dredged both on Magnetic Island and in other locations. In 1957
1598-401: The jetty channel from littoral drift, and cause the discharge of the river to maintain it out to deep water. The channel, also, beyond the outlet of the river Nervion into the Bay of Biscay has been regulated by jetties; and by extending the south-west jetty out for nearly 0.5 miles (0.80 km) with a curve concave towards the channel the outlet has not only been protected to some extent from
1645-473: The jetty's role in the commercial, family and recreational life of the Island community. The importance of the jetty to the island community was recently demonstrated through the proposal to set up a management committee to assume responsibility for the structure once it becomes obsolete to requirements. The place has a special association with the life or work of a particular person, group or organisation of importance in Queensland's history. The present jetty
1692-468: The jetty, has timber handrails along both sides. The remainder of the jetty is used as a driveway for luggage and emergency vehicles meeting the ferry. There is no safety rail along the outer side of the jetty. The walkway is lit with six evenly spaced fluorescent lights. Lighting is also located in the shelter sheds at the end of the Jetty. The sheltered area at the end of the Jetty is made up of three structures. One shed , which appears to be older,
1739-420: The major user of the facility. The Fund, which generated resources through the collection of berthing fees, provided income for jetty maintenance. By 1984, although the company no longer had a lease on the jetty, it was berthing up to 3,640 times compared to 1,150 other berthings with a total of 250,000 to 300,000 people using the jetty annually. In November 1985 the Townsville Harbour Board sought approval from
1786-678: The mouths of a deltaic river flowing into a tide — a virtual prolongation of its less sea, by extending the scour of the river out to the bar by banks. Jetties prolonging the Sulina branch of the Danube into the Black Sea , and the south pass of the Mississippi River into the Gulf of Mexico , formed of rubble stone and concrete blocks, and respectively, have enabled the discharge of these rivers to scour away
1833-425: The older jetties, in such long-established jetty ports as Calais , Dunkirk and Ostend , was composed of clay or rubble stone, covered on the top by fascine-work or pitching, but the deepening of the jetty channel by dredging and the need that arose for its enlargement led to the reconstruction of the jetties at these ports. The nes jetties at Dunkirk were founded in the sandy beach, by the aid of compressed air, at
1880-412: The reduction of its scouring force, is no longer able at a moderate distance from the shore effectually to resist the action of tending to form a continuous beach in front of the outlet. Hence a bar is produced that diminishes the available depth in the approach channel. By carrying out a solid jetty over the bar, however on each side of the outlet, the tidal currents are concentrated in the channel across
1927-477: The river at a suitable site, by carrying a jetty on each side of this outlet across the beach, thereby concentrating its discharge in a definite channel and protecting the mouth from being blocked up by littoral drift. This system was long ago applied to the shifting outlet of the river Yare to the south of Yarmouth , and has also been successfully employed for fixing the wandering mouth of the Adur near Shoreham , and of

1974-405: The sea is liable on an exposed coast to block up its outlet during severe storms. The river is thus forced to seek another exit at a weak spot of the beach, which along a low coast may be at some distance off; and this new outlet in its turn may be blocked up, so that the river from time to time shifts the position of its mouth. This inconvenient cycle of changes may be stopped by fixing the outlet of
2021-404: The slope, at the ends of which vessels can lie in deep water or more solid structures are erected over the slope for supporting coal-tips. Pilework jetties are also constructed in the water outside the entrances to docks on each side, so as to form an enlarging trumpet-shaped channel between the entrance, lock or tidal basin and the approach channel, in order to guide vessels in entering or leaving
2068-520: Was constructed under a permit issued by the Queensland Department of Harbours and Marine. It was built using Federal funds and leased to Magnetic Island company Hayles Magnetic Pty Ltd. The company was associated with tourist ventures on Magnetic Island from 1898 and leased the present jetty from 1960 until 1981. Tourism on Magnetic Island began with the Butler family who first settled on the Island in 1877. Harry Butler and his family established
2115-448: Was granted a permit to construct a jetty at Picnic Bay. While it is possible that this permit was for a second jetty it is unlikely that the Hayles Company waited six years to replace the jetty damaged in the 1903 cyclone. A letter dated 1 February 1917 from the Townsville Harbour Board to the Marine Department indicated that there were two jetties at Picnic Bay and one at Nelly Bay . These privately owned jetties were in poor condition and
2162-423: Was granted creek frontage on which to build a landing depot. A new twenty-year lease agreement, granting the Hayles Company a 30-foot (9.1 m) Flinders Street frontage to Ross Creek for the construction of another depot, was signed in 1925. To facilitate his tourism venture Robert Hayles began a program of purchase or construction of small ferries. His first purchase, from Sydney , was a small steam ferry called
2209-545: Was responsible for the maintenance of the structure. The shelter shed at the end of the jetty was constructed under a Community Employment Program through the Townsville City Council in 1977. The jetty was damaged during Cyclone Althea on Christmas Eve 1971 but remained structurally sound. At the end of the lease in 1981 the Picnic Bay Jetty Maintenance Fund was established with Hayles Magnetic
