The Portland was built at Bristol in 1822. She was 385 tons with a length of 107'5'; breadth (below 28' 4'; height (cabin) 6' 1'; quarter, main and forecastle decks; three masts; square stern; ship rig; quarter galleries and bust head. 
The Portland transported convicts to New South Wales in 1832 and 1833.
The Convicts came from counties in England and Scotland - Norfolk, Middlesex, Cambridge, Southampton, London, Wiltshire, Essex, Lancaster, Huntingdon, Hereford, Salop, Sessex, Warwick, Berks, Northampton, Oxford, Surrey, Suffolk, Stafford, Worcestershire, Edinburgh, Jamaica and Gibraltar.
Their crimes included various forms of stealing, robbery, house robbery, forgery, passing base coin, embezzlement, poaching, picking pockets etc., There were few if any violent criminals amongst them. Most of the Swing rioters to New South Wales had been transported on the Eleanor in 1831, however at least three prisoners on the Portland had also been involved in Swing Riots.....
James Baker from Baskingstoke convicted of machine breaking at Reading in December 1831, Job Hatherell from Wiltshire convicted of sending a threatening letter and Robert West from Lynne convicted of machine breaking
There were also two soldiers who had been court-martialled.......
Philip Murray from Co. Tyrone was court martialed for desertion in Jamaica and sentenced to 7 years transportation and Hugh O'Neill from Co. Tyrone was court martialed for desertion in Gibraltar and sentenced to 7 years transportation
The convicts were held in the Captivity, Leviathan and York hulks where they had worked in the Dock-yard from seven o'clock until, twelve, in the mornings, and from a quarter past one o'clock until half past five, in the afternoons.
The Captivity, pictured centre below, had three decks, the under-deck being an additional one, with ports cut to admit light. The officers consisted of an overseer, or captain, three mates, a surgeon, a chaplain, with inferior officers, quarter-masters, and guards, amounting to nineteen in number. Divine service was performed twice, weekly, by the chaplain.
The Captivity, was formerly the Bellerophon man-of-war, of 74 guns, to which ship, when commanded by Captain Maitland, and cruising in Basque Roads, off Rochefort, the Emperor Bonaparte surrendered himself, about six o'clock A.M. on the 15th of July, 1815.* Near the margin, on the left, is the Sheer-hulk, used for fixing the masts and rigging of the vessels in the harbour. The Bellerophon was paid off and converted to a prison ship in 1815, and was renamed Captivity in 1824 to free the name for another ship. Moved to Plymouth in 1826, she continued in service until 1834, when the last convicts left. The Admiralty ordered her to be sold in 1836, and she was broken up.
One hundred and seventy-eight male prisoners were embarked at Spithead on 14 November 1831.
Most of the Portland prisoners were young men in a good state of health with the exception of a few who suffered chronic leg ulcers.
Lieutenant Archer of the 16th regiment commanded the Guard and travelled as a cabin passenger. The Guard consisted of two non-commissioned Officers, 27 Privates of the 4th and 39th regiments, two women and four children who all travelled in steerage.
Surgeon Joseph Cook
Joseph Cook kept a Journal from 21st October 1831 to 11 April 1832. The Portland did not depart Spithead until 27 November 1832 and Joseph Cook reported that during that time the winds and weather were variable. Catarrh appeared as an epidemic during these days and continued to recur during the whole of the voyage, almost all on board having been affected with it more or less, but in the greater number of instances so slight as not to require confinement or medical treatment. The prisoners were also much affected with costiveness induced by sea sickness and change of diet but the general state of health on board during the voyage was good.
The leg ulcers they had suffered with on arrival on the Portland speedily recovered under the surgeon's treatment of adhesive straps and a change of air and better diet.
The Portland was off the coast of Brazil on 14th January 1832. During the voyage the convicts were admitted on deck daily as much as the state of weather and other circumstances permitted, one half taking their meals on deck alternatively. Attention was paid to cleanliness and the between decks kept as dry as possible. The surgeon did not report heavy rain until off the coast of Australia when they also experienced westerly winds. The temperature occasionally reached 89° in the prison at nights while passing through the tropics. 
Joseph Cook was employed as Surgeon Superintendent on the convict ships Phoenix in 1826, Southworth in 1822,Sir Charles Forbes in 1825 (VDL), Louisa in 1827, Mellish in 1829, Forth (11) in 1830 and the Portland in 1832. In all those voyages only four prisoners died under his care.
Those treated by the surgeon during the voyage included:
Bridget Halpin, aged 40, soldier's wife;
Elis Halpin, aged 2 months, soldier's child
Thomas Allcock, aged 20, convict;
G Kendall, aged 24, private, 39th Regiment;
William Jones, aged 54, convict; contusion having accidentally slipped down the main hatch way ladder;
David Hall, aged 53, convict;
James Thomson, aged 17, convict;
David Price, aged 24, convict;
Richard Clough, aged 28, convict; c.
William Toll, aged 38, convict;
Thomas Lucas, aged 21, convict.
The Portland arrived in Port Jackson on 26th March 1832.
A Muster was held on board by the Colonial Secretary on 29th March 1832. There had been no deaths on the voyage and 178 male convicts, the original number, were landed at Sydney on 6th April 1832. All except one, William Toll who had suffered scurvy, were fit for immediate employment.

6). George Green late of Paterson labourer, was indicted for the wilful murder of Diamond an aboriginal near Paterson on 3rd of January 1836. The prisoner was a shepherd in the employ of Mr. Walter Windeyer at the period in question; the country at that time was in a very disturbed state on account of the hostility of the blacks who had committed several murders and robberies in that district; the atrocities at length rose to such a pitch that the shepherds and stockmen refused to go out unless armed; the prisoner was consequently allowed a pistol for his protection. On the day in question while he was driving his sheep, he was set upon from behind by several blacks who pinioned his arms, and others proceeded to drive the sheep together, as was supposed to drive away; the prisoner struggled very much and succeeded in extricating himself and drew his pistol from under his coat and fired at the party and then ran for his life. A few days afterwards the mangled remains of a human body were found near the scene of the contest, which were said to be the remains of Diamond a black who had been missing since the day in question and was reported to have been shot by Green; an inquest was held but the Jury came to no satisfactory conclusion and the matter dropped for many months till raked up by the Crown officers. Mr. Windeyer was called by the prisoner for character and a remark of that gentleman caused a little amusement when he described the prisoner to be moderately honest. The Jury without hesitation returned a verdict of Not Guilty. Sydney Monitor 14 August 1837
