The North Head Quarantine Station is a heritage-listed former quarantine station and associated buildings that is now a tourist attraction at North Head Scenic Drive, on the north side of Sydney Harbour at North Head, near Manly. It is also known as North Head Quarantine Station & Reserve and Quarantine Station & Reserve. The property is owned by the Office of Environment & Heritage. The buildings and site were added to the New South Wales State Heritage Register on 2 April 1999. The entire North Head site, including the Quarantine Station and associated buildings and facilities, was added to the Australian National Heritage List on 12 May 2006, and now forms part of the Sydney Harbour National Park.

The complex operated as a quarantine station from 14 August 1832 to 29 February 1984. The concept behind its establishment was that, as an island-nation, the Colony of New South Wales, as it then was, was susceptible to ship-borne disease. Those who might have an infectious disease would be kept in quarantine until it was considered safe to release them. The isolation and strategic role of North Head was recognised in 1828 when the first vessel, the Bussorah Merchant, was quarantined at Spring Cove. The importance and future role of North Head was reinforced by Governor Darling's Quarantine Act of 1832, which set aside the whole of North Head for quarantine purposes in response to the 1829–51 cholera pandemic in Europe.

The station is now home to a hotel, conference centre, and restaurant complex known as Q Station,Q Station Homepage and remains part of the Sydney Harbour National Park. One of the early quarantine officers was Dr James Stuart, a keen naturalist and painter. For many years Percy Nolan, an alderman and mayor of Manly, pushed for the removal of the Quarantine Station from Manly and called for its use as public open space. Over sixty years later, this far-sighted proposal became a reality.

In the 1960s and 70s, the officer then in charge of the Quarantine Station, Herb Lavaring BEM (1917–1998), took it upon himself to preserve and compile a museum of artifacts and other items of note and significance to the station's operations, including domestic implements, medical instruments, and hand tools for tasks ranging from blacksmithing to building construction. Lavaring collected these materials over the period 1963–1975 and also commenced restoration work on the diverse range of rock carvings and headstones from the major burial grounds. The items collected by Lavaring were preserved, and many have since found their way into state and federal collections, including the National Museum of Australia in Canberra, where a muzzle-loading rifle and a set of manacles are preserved (the latter being used to ensure that no one left the station without medical clearance).

One of the most historic features of the quarantine station is the series of engravings along the escarpment adjacent to the jetty. The carvings were executed by people staying at the quarantine station, and cover an extensive period that stretched from the early nineteenth century to the mid-twentieth century. Some were executed by stonemasons and sculptors and show a high degree of skill. More carvings are located at the rock formation known as Old Man's Hat.

History The Quarantine Station was established primarily to regulate the risk of disease importation through the migration of free and convict Europeans, and the arrival of merchant shipping. There was always a close link between the requirement for quarantine and the ebb and flow of sea-borne immigration; and the growth of the Quarantine Station from the 1830s parallels the changes in immigration policy and practice. The other major influence was the imperative to limit disruption to the increasingly commercially-sensitive shipping industry.

As the dominant headland of the harbour, North Head was of importance in navigation from the time of the First Fleet. By 1809 navigational plans were showing an obelisk, located in what was to become the Quarantine Station precinct, presumed to have been used as a channel marker for vessels negotiating the Sow and Pigs Reef. A obelisk still exists on this site, which may be the original marker, making it potentially one of the oldest European structures on Sydney Harbour.

Up until the 1830s, the majority of ships requiring quarantine were convict transports, and being under government contract, the somewhat informal proclamation of quarantine by the Governor of the day was easy to enforce. One reason for the introduction of formal statutory regulation for quarantine in NSW in 1832 was the increasing rate of free immigrant vessels entering port. In 1831 thirty four immigrant ships had arrived, and this increased to 63 in 1832. The captains of these free vessels were less ready to comply with such informal and ad hoc processes, thus a legislated requirement for all ships entering port to be screened for disease, and quarantined if necessary, was needed.

Another problem with the changing nature of the shipping entering Sydney was the increasing time constraints placed on the captains of commercial vessels, necessitating rapid turn-around in port-time wasted in port, and in quarantine, was income lost. The convict ships, under government contract, could be isolated for the period of quarantine with little added expense, but free commercial carriers sought demurrage from government for any delays it imposed. In part, the disruption to shipping caused by traditional quarantine practices led to the progressive move away from detention-based quarantine in Britain through the middle years of the 19th century.

Following passage of the Quarantine Act, 1832 When the 1832 Quarantine Act was passed in NSW, Viscount Goderich, British Secretary of State for War and Colonies, warned that quarantine was prejudicial to the trade of the kingdom and that the colony should be aware of the importance of "not aggravating by unnecessary restrictions the embarrassment inseparable from a strict quarantine on British Vessels".

The initial quarantine practice of housing the sick on board the vessel in which they arrived, was dispensed with after the experience with the long detention of the Lady Macnaghten in 1837, and the subsequent heavy demurrage claimed for that delay. After that time the sick were removed from their ship and housed ashore, while the ship was fumigated and scoured for return to the owner with the minimum delay. A consequence of this decision was the construction of permanent accommodation and stores buildings at the Quarantine Station at North Head.

The alarming experiences of quarantine in 1837 and 1838 prompted a review in the colony of the organisation and conditions aboard immigrant ships. The final report, arising as a NSW initiative, pricked the sensitivities of the British emigration officials, but nevertheless had positive outcomes. The review indicated that there was insufficient checking of the health of the emigrants before boarding; there was insufficient concern with diet during the voyage, especially for the needs of children; and that the formula of three children equalling one adult when allocating food and berth space aboard required reconsideration, as it led to excessive number of children in cramped spaces, with inadequate food. Finally it indicated that the surgeon-superintendent aboard ship required more authority to regulate and promote good health and good order among the emigrants.

The subsequent reorganisation of the system resulted in interviews and medical checks on would-be emigrants before embarking them; vaccination for smallpox of all emigrants; the signing of undertakings to follow the directions of the surgeon-superintendent on voyage and better definition of his role and powers; improvements in diet and hospital accommodation aboard; and moves to prevent overcrowding.

The rate of mortality improved dramatically. In 1840 the death rate for children fell from one in ten to one in seventeen, and that for adults also fell. With the improved conditions the rate of quarantine declaration of immigrant ships also fell in 1840, from three ships out of 43 in 1839 to one out of 40 in 1840.

Immigration was reduced from 1842 due to the economic recession in the colony, as the decline in land sales had reduced the pool of funds earmarked to support the migration scheme. Immigration was at a standstill from 1842 until 1848, and only one ship was quarantined in this period. The resumption of immigration in 1847-48 led to a review of the adequacy of the Quarantine Station, but no real increase in accommodation resulted.

The arrival of the Beejapore in 1853, with over one thousand passengers, at a time when the Quarantine Station could accommodate 150 persons, triggered a new building phase. As a temporary measure, the hulk Harmony was purchased and moored in Spring Cove as a hospital ship. The Beejapore was an experiment in trying to reduce migration costs by using two-deck vessels, and the outcome was judged not to be a success. Fifty-five people died during the voyage, and a further sixty two died at the Quarantine Station, from the illnesses of measles, scarlet fever and typhus fever. The majority of the passengers and crew had to be housed in tents. The biggest impetus for change came not so much from a concern about poor housing, but rather a concern for the morals of the married women and the "200 single women let loose in the bush" that represented the undeveloped station at that time. The resulting changes to the station, besides the use of the hospital ship, included the construction of a barracks for the single women in the former Sick Ground, surrounded by a double fence with a sentry stationed between them, to prevent communication with the women. Two new buildings were built in the Healthy Ground, each to house sixty people, with verandahs for dining. The original burial ground was levelled and the grave stones removed to the new burial ground, thus further removing the burials from the view of the Healthy Ground. Eight quarters were also built for the Superintendent.

1860s to 1890s The downturn in immigration during the economically stagnant period of the 1860s, triggered by the colonial government cancelling the regulations to provide assisted passage to migrants in 1860, limited the use of the Quarantine Station, and the willingness of the government to spend money on its upkeep. As a result of this downturn between 1860 and 1879 only 138 immigrant vessels arrived [compared with 410 between 1840 and 1859], and of these 33 required cleansing at the Quarantine Station, but few required their passengers to be landed and accommodated. In the same period 29 merchant or naval vessels were quarantined, but again mainly for the cleansing of the ship rather than the landing of diseased crews.

The run-down Quarantine Station had become unsuitable for passenger quarantine, and particularly for first and second class passenger accommodation, by the time the Hero was in need of quarantine for smallpox in 1872. The passengers were kept aboard the ship, because the station could not adequately house them. The inadequacy was further publicised during the quarantine of the Baroda in 1873, when first class passengers had to do their own washing. Well-connected passengers ensured that government attention was focussed on the shortcomings of the Station accommodation. As result, a new group of First Class accommodation buildings were built in the Healthy Ground.
