The Dunvegan Castle was built at Chittagong in 1819.  Convicts were transported to New South Wales on the Dunvegan Castle on this voyage in 1830 and in 1832.
The prisoners came from counties throughout England and Scotland including Stafford, Gloucester, Manchester, Liverpool, Bedford, Warwick, Edinburgh and Middlesex. Most had been held on prison Hulks before being embarked on the ship. Some of the men were embarked at Woolwich on the 16th; and on the 21st September at Sheerness. One of the convicts died that same evening.
The military guard were embarked on the 11th. The Guard consisted of soldiers of the 17th, 44th, 27th and 63rd regiments., under orders from Lieut. John Grey. Six women and 12 children accompanied the military guard. Select here to find convicts ships bringing detachments of the 63rd and 17th regiments.
Passengers included Mrs. Grey and daughter, Mr. and Mrs. Lipscome Kentish, and Mortimer Lewis, wife Elizabeth nee Clements, three sons and one daughter.
Mortimer Lewis had been appointed assistant surveyor in the office of the surveyor-general Sir Thomas Mitchell. Moritmer Lewis mapped the Dividing Range west of Sydney and later was appointed town surveyor. In 1835 he was appointed colonial architect, a post he held for fifteen years. He designed the Newcastle Court House and assisted in laying the foundation stone of the Maitland Gaol. His son Mortimer Lewis (jun) married Ellen Stacy, daughter of Dr. John Stacy of Newcastle and lived for a time in the Military Barracks at Newcastle
Surgeon Robert Dunn
This was Robert Dunn's second voyage as surgeon superintendent on a convict ship. He was appointed to the Dunvegan Castle on the 8th of September 1829. He kept a medical journal from 8 September 1829 to 10 April 1830. He rejected one of the soldiers and inspected the ships crew in order to prevent any possibility of contagions or infectious diseases being introduced into the ship as had been the case in his last voyage, the Bussorah Merchant in 1828
The Dunvegan Castle became the last convict ship to transport prisoners before the establishment of the Metropolitan Police Force introduced by Sir Robert Peel. Before September 1829 the watchmen, familiarly called 'Charlies,' who guarded the streets of London, were often incompetent and feeble old men, often unfit for their duties. 
The Dunvegan Castle departed Sheerness on 30 September 1829.
This was a particularly long voyage because of contrary winds which resulted in an inrease in number of men requiring medical treatment. Robert Dunn described some of the difficulties of the voyage in his journal......
The weather during September was cold for the season and accompanied with a damp atmosphere and frequent showers and they did not clear the Channel until the 20th October 1829. During October the weather remained cold with constant westerly gales however the prisoners remained healthy at this time except for a few slight cases of Catarrhal. During this time convict William Harris almost had his ear torn off when a cask landed on his head on the 5th October.
In the months of November and December they experienced nothing but light winds and hot sultry weather and were nearly all that time inside the tropics. From light baffling winds they did not pass the Cape of Good Hope till the 4th of January. When they got into high southern latitudes where heavy gales and damp weather could be expected they experienced only light and contrary winds so that instead of making the passage from the Cape to Sydney in six weeks they took eleven weeks to reach Van Diemens Land. The medical comforts were expended by this time and water was running out, so they called at Hobart Town on 13th March and remained there eleven days. Four convicts had died on the passage or in the hospital at Hobart from scurvy -
Isaac Wilson 1 March,
William Caley 7 March,
Thomas Sanson 9 March,
George Dunn on 10 March.
The remaining convicts recovered with fresh beef and vegetables in that time and the ship resumed her voyage to Sydney.
Robert Dunn's general remarks at the end of the voyage - I cannot conclude these remarks without stating for the information of your Honourable Board that the lemon juice was sent on board in casks instead of bottles. This consequence was that it was so thick that it had the appearance of fine soup than anything else I could compare it to and from this circumstance the convicts instead of drinking it with that avidity formerly, loathed it. It was only by standing by that I got them to drink it. I dont consider that it had that anti-scorbutic effect I have often witnessed it to have. Two cases sent on board in bottles which I kept for the use of the hospital and worst cases of scurvy I found it not only checked the disease but many got well under its influence. I mixed it with nectar and I cannot say enough in praise of this last valuable medicine in that loathsome disease.
The Dunvegan Castle arrived in Port Jackson via Hobart on 30 March 1830 with 175 male prisoners. The voyage had taken 181 days.
Prisoners were mustered on board by the Colonial Secretary on 1st April. A total of five had died on the voyage out. The convict indents record each prisoners name, age, education, religion, marital status, family, offence, sentence, native place, date and place of trial, former convictions, physical descriptions and where and to whom the convicts were assigned. There is also occasional information regarding colonial crimes, deaths and pardons.
